Electrochemical conversion of CO 2 to value-added chemicals is a promising carbon recycling strategy for mitigating CO 2 emissions from fossil fuels and addressing associated environmental challenges. In copper-based catalysts, Cu + species promote the reduction of CO 2 to multi‑carbon products, such as ethylene (C 2 H 4 ). However, under typical electroreduction, Cu + is prone to reduction to Cu 0 , leading to degradation of catalytic performance and poor stability. Herein, we present an interfacial engineering strategy to design a CuI-Cu 2 O composite catalyst with densely packed Cu 2 O nanoparticles on tetrahedral CuI substrates and self-stabilizing Cu + ability for selective CO 2 electroreduction to C 2 H 4 . Density functional theory (DFT) calculations and spectroscopic characterizations demonstrated that the CuI-Cu 2 O catalyst combined the efficient generation of *CO intermediates by Cu 2 O with the efficient C C coupling functionality of CuI, and the iodide ions within the catalyst autonomously modulated the copper oxidation state to stabilize Cu + , collectively enhancing CO 2 -to-C 2 H 4 selectivity. Consequently, the CuI-Cu 2 O catalyst achieved a C 2 H 4 Faradaic efficiency of 62.98 ± 1.05% along with a high current density of 275.16 mA·cm −2 at −0.97 V vs. the reversible hydrogen electrode (RHE). In the stability test, the CuI-Cu 2 O catalyst operated stably for over 16 h at a current density of approximately 279.95 mA·cm −2 . This study provides a catalyst design strategy that simultaneously enhances *CO supply and C C coupling while autonomously modulating the active Cu + state, offering an effective approach for achieving stable and highly selective CO 2 -to-C 2 H 4 conversion.

Electrocatalytic CO 2 reduction to multi‑carbon products offers a sustainable route to fuels and chemicals, yet suffers from sluggish C C coupling and competing hydrogen evolution. Here, we report a rationally engineered Cu 3 N/Cu@C heterostructure catalyst that delivers markedly enhanced CO 2 electroreduction performance. The optimized catalyst achieves a 65.3% Faradaic efficiency toward multi‑carbon products and a half-cell energy efficiency of 35.3% at −1.1 V versus reversible hydrogen electrode. Combined in situ attenuated total reflectance surface enhanced infrared absorption spectroscopy and density functional theory calculations reveal that interfacial charge transfer at the Cu 3 N/Cu junction modulates the electronic structure of Cu sites, elevates local pH, strengthens CO 2 adsorption and activation, and suppresses hydrogen evolution. Importantly, the tailored interface facilitates asymmetric C C coupling between *CO and *COH intermediates, stabilizing the key *OCCOH species and accelerating multi‑carbon products formation. This work underscores heterointerface engineering as a powerful strategy to control reaction microenvironments and C C coupling pathways, guiding the development of high-performance copper-based CO 2 reduction reaction catalysts.

The electrocatalytic formaldehyde oxidation reaction (FOR) offers a unique pathway for simultaneous hydrogen and formate generation at the anode, presenting an energy–efficient alternative to the oxygen evolution reaction for hydrogen production. However, the inherent activity and stability of Cu–based electrocatalysts for FOR are still not satisfactory for practical application, primarily due to the facile oxidation of active Cu 0 sites to inactive Cu + /Cu 2+ species during operation. Herein, we construct a Cu/Ni heterojunction electrode via facile electrodeposition. Experimental and spectroscopic characterizations confirm interfacial electron transfer from Ni to Cu, creating an electron–rich Cu surface that resists oxidative deactivation. This electronic modulation results in exceptional FOR performance, achieving 100 mA·cm –2 at 0.1 V vs. RHE and remarkable stability over 100 h. In situ measurements further reveal that the optimized electronic structure of the Cu/Ni heterojunction electrode enhances the adsorption and conversion of the key H 2 C(OH)O intermediate. A bipolar H 2 production device incorporating a Cu/Ni anode achieves 100 mA·cm –2 at a cell voltage of 0.14 V. This work demonstrates the promise of interfacial electronic engineering in developing efficient catalysts for energy–saving hydrogen production.

A Cu: MoO 3 /g-C 3 N 4 binary heterojunction photocatalyst was synthesized via a hydrothermal method, achieving a light response that covers nearly the entire visible region. The material shows a strong, broad absorption band from 400 to 700 nm, significantly improving its visible-light harvesting and utilization efficiency. Optimization of the g-C 3 N 4 , Cu, and Mo molar ratios further enhanced the catalyst’s redox performance under visible-light irradiation. Through combined XPS, UV–vis, and in situ DRIFTS characterizations, it was verified that the Cu: MoO 3 /g-C 3 N 4 photocatalyst possesses a wide visible-light absorption range and effectively transforms absorbed long-wavelength photons into photogenerated electron-hole pairs, thereby facilitating the separation and transfer of charge carriers. Due to the simultaneous enhancement of broad-spectrum light capture and charge separation/transfer efficiency, this catalyst demonstrates excellent catalytic activity in visible light-driven CO 2 conversion, with a maximum methanol production rate of 102.52 μmol·g −1 ·h −1 . This work verifies the feasibility of efficient visible light-driven CO 2 conversion and provides a viable design approach and reference for constructing multi-metal-based photocatalysts with full visible light response.

Electrode materials typically suffer from an inherent trade-off between arc erosion resistance and electrical conductivity. In this work, Cu-10W composites containing of 0, 0.1, 0.3, and 0.5 wt% graphene (Gr) was fabricated via near-net-shape hot isostatic pressing (HIP), and their microstructures and properties were systematically investigated. Among these composites, the Cu-10W-0.1Gr composite exhibited the most balanced performance, achieving a relative density of 98.57%, tensile strength of 317 MPa, elongation of 22.2%, and electrical conductivity of 87.6%IACS. Microstructural analysis revealed that the mechanical and electrical enhancements mainly originated from the dispersion strengthening induced by nano-sized W particles dispersed within the Cu matrix, combined with the optimization of the conductive network by Gr located at grain boundaries. Benefiting from the high electrical conductivity and low work function of Gr, under a 30 V DC and 35 A test condition, the addition of a 0.5wt.%Gr reduced mass loss and erosion rate by up to 24.0%, decreased average arc energy by up to 47.9%, effectively suppressed welding force, and maintained stable contact resistance. This work mitigates the longstanding strength-conductivity dilemma in Cu-based electrode materials, and provides a viable design strategy for high-performance electrical contact composites.

Aqueous phase reforming of methanol (APRM) provides a promising strategy for in-situ hydrogen production, yet its practical application is hindered by insufficient catalyst activity and stability. Herein, we report a carbon-coated copper catalyst with uniformly dispersed nanoparticles for efficient APRM. The Cu@C catalyst exhibits significantly enhanced performance in the presence of KOH, achieving an average hydrogen productivity of 236.2 μmol H2 /g cat. /s at 220 °C, nearly triple that under alkali-free conditions. Notably, the hydrogen purity reaches 99.99% with negligible CO x and alkane byproducts. Mechanistic studies reveal that methanol reforming proceeds via the methyl formate pathway, while KOH promotes reaction efficiency mainly by in-situ CO 2 capture to form KHCO 3 and by removing poisonous CO species. The synergy between Cu@C and KOH boosts catalytic activity, ensures high-purity hydrogen production, and offers a viable approach for stable and scalable APRM-based hydrogen generation.

Rapid electrification and renewable-energy infrastructure expansion demand copper materials simultaneously achieving high conductivity and robust structural performance. To address this, the study developed a strategy that couples a solution–solid displacement reaction with electrostatic self-assembly to construct hierarchical MXene/Ag@Cu composite powders, thereby achieving dual molecular-level compositing of Ag and MXene. During sintering, the Ag formed a continuous strip-like Ag phase within the Cu matrix, thereby establishing efficient dual pathways for electron and mechanical conduction, as confirmed by both microstructure characterization and finite element simulation. The first-principles analyses further revealed that Ag acts as an interfacial coupling element, effectively bridging self-lubricating MXene nanosheets with the Cu matrix, thereby enhancing electron transport, load-bearing capacity, and tribological performance. Furthermore, the Ag–MXene architecture was shown to construct a robust physicochemical barrier. Thermophysical measurements indicated its role in managing frictional heat, while first-principles simulations revealed its high energy barrier against O diffusion, collectively mitigating oxidative wear. Benefiting from multiscale synergistic reinforcement, the Cu-matrix composite simultaneously achieved high conductivity (96.3% IACS), excellent strength (354.3 MPa), and an ultralow wear rate (1.72 × 10 − 6 mm 3 N -1 m -1 ). These results demonstrate that the hierarchical Ag–MXene architecture successfully overcomes the conventional conductivity–strength–wear-resistance trade-off, offering a promising strategy for next-generation high-performance copper in advanced energy and industrial applications.

Photothermal hydrogenation of CO 2 offers a solar-driven route to multicarbon hydrocarbons, but controlling carbide formation and maintaining reconstructed active sites remain challenging for iron-based catalysts. Here, we develop a trace Al/Rb co-promoted CuFe 2 O 4 catalyst that enables efficient and stable photothermal CO 2 hydrogenation to light olefin under ambient pressure. The optimized catalyst achieves high C 2 -C 4 olefin selectivity of approximately 63%, suppressing CH 4 selectivity and sustaining stable photothermal-catalytic performance for 200 h. Integrated experimental characterizations and theoretical calculations reveal that the CuFe 2 O 4 precursor undergoes reaction-induced reconstruction to form Cu-Fe 5 C 2 interfacial structures. Trace Al/Rb promotion facilitates the formation and stabilization of reconstructed metal–carbide interfaces, with Al regulating the Fe-centered coordination environment and carbide stability, while Rb tunes the interfacial electronic structure and adsorption–hydrogenation balance. This cooperative regulation stabilizes carbide-based interfacial active sites and promotes CO 2 -derived C 1 intermediates toward C–C coupling and C 2 -intermediate stabilization, thereby favoring C 2 -C 4 olefin formation.

The development of lightweight, low-cost, and high-performance non-precious metal electrocatalytic electrodes is critical to advancing the practical implementation of methanol and urea oxidation reactions (MOR and UOR) in next-generation energy conversion systems. Herein, we reported a facile synthesis of a W-Se co-modified porous Ni/Cu paper electrode (W-NiSe/Cup) via synchronous pulse electrodeposition onto filter paper-derived porous Cu foil. The hierarchical porosity and high specific surface area originated from the paper template, while synergistic electronic modulation among Ni, W, and Se enhanced intrinsic catalytic activity. At 0.8 V, the W-NiSe/Cupelectrode delivered current densities of 298 mA·cm−2(MOR) and 305 mA·cm−2(UOR) with a lower-mass loading, representing 1.29-fold and 1.34-fold enhancements over the Ni/Cupelectrode. Furthermore, the electrode exhibited exceptional durability: under chronopotentiometry operation at 100 mA·cm−2in a 6-fold-concentrated electrolyte (6 M KOH + 3.0 M CH3OH + 1.98 M CO(NH2)2), the operating potentials retained 95.74% (MOR) and 118.05% (UOR) of their initial values after 9 h. This study offers a novel strategy for designing lightweight non-precious metal catalytic electrodes for portable energy devices and also verifies the broad potential of biomass templates in constructing advanced energy electrocatalytic materials.

Prostate cancer is a prevalent immune-cold malignancy in which hypoxia and glutathione (GSH) enrichment hinder redox-dependent therapies and cuproptosis. A hyaluronic-acid–coated copper–manganese Prussian blue nanomedicine (Cu/Mn-PB@HA) was developed to remodel the tumor microenvironment (TME) and enhance mitochondria-associated cuproptosis. The multivalent Cu/Mn centers enable catalase-like O 2 generation, GSH-oxidase–like depletion of GSH, and Fenton-like ·OH production, which together enhance chemodynamic therapy (CDT) and create a favorable window for cuproptosis. In acidic and GSH-rich conditions, copper valence cycling initiates cuproptosis, whereas released Mn 2+ enhances CDT and activates the cGAS–STING pathway, thereby promoting dendritic-cell maturation and cytotoxic T-cell responses. The HA shell enables CD44-mediated enrichment, improving tumor accumulation without compromising biosafety. In vitro , the platform elevates ROS, induces mitochondrial depolarization, downregulates HIF-1α, and modulates cuproptosis-related proteins. Concurrently, immunogenic cell-death markers are elevated together with cGAS–STING signaling. In vivo , preferential tumor accumulation and significant tumor inhibition are achieved with favorable serum biochemistry and hepatic/renal histology. By integrating “oxygenation–desensitization–ROS” chemistry with Mn 2+ - enhanced immune activation, Cu/Mn-PB@HA provides a comprehensive strategy for treating immune-cold solid tumors and serves as a versatile platform for theranostic development.

A series of Cu-modified Ni–Al2O3 catalysts with various Cu/Ni ratios (xCu/Ni–Al2O3) were prepared, and systematically characterized using BET, XRD, SEM, H2-TPR, H2-TPD, TG, and XPS. The catalyst exhibited excellent catalytic performance in the selective hydrogenation of N,N-dimethylaniline to N,N-dimethylcyclohexylamine in a continuous fixed-bed reactor. When the Cu/Ni molar ratio was 0.1, the active components were highly dispersed on the Al2O3 support, which possessed a high specific surface area and well-developed porous structure. Furthermore, the catalyst demonstrated strong hydrogen desorption capacity and enhanced thermal stability. Synergistic electronic interactions between Ni and Cu improved the adsorption and activation of both reactant and H2 molecules. The incorporation of Cu near the Ni active sites effectively modulated the selectivity toward the desired product N,N-dimethylcyclohexylamine. Under the optimal reaction conditions: H2 pressure of 5 MPa, reaction temperature of 130 °C, liquid hourly space velocity 0.1 h−1 and hydrogen-amine volume ratio of 5500 : 1, the 0.1Cu/Ni–Al2O3 catalyst achieved superior performance, with a N,N-dimethylaniline conversion rate of 99.5% and a selectivity for N,N-dimethylcyclohexylamine of 97.6%.

Designing multifunctional nanotherapeutic platforms that integrate multiple therapeutic capabilities with enhanced tumor specificity and low systemic toxicity has emerged as a promising strategy for cancer therapy. Herein, we put forward a simple and clear route to construct multifunctional nanoparticles (NPs) integrating chemodynamic therapy (CDT), starvation therapy (ST), and photothermal therapy (PTT) by using polydopamine as a protective layer to coat Cu2+-doped zinc phosphate loaded with glucose oxidase (designated as Cu-ZnP@GOx/PDA/PEG NPs) for optimizing therapeutic efficacy. The obtained Cu-ZnP@GOx/PDA/PEG NPs utilize porous Cu2+-doped ZnP to provide sufficient space for efficient GOx loading, while the PDA shell coated on the surface acts as a “gatekeeper” to prevent enzyme leakage and provides photothermal conversion capabilities. When Cu-ZnP@GOx/PDA/PEG NPs accumulate at tumor sites, the slightly acidic tumor microenvironment triggers the degradation of Cu-ZnP@GOx/PDA/PEG NPs, thereby releasing loaded GOx and doped Cu2+. The released Cu2+ is reduced to Cu+ by glutathione (GSH), subsequently catalyzing H2O2 decomposition to generate highly cytotoxic hydroxyl radicals (•OH) for effective CDT. The released GOx can cut off glucose metabolism in tumor cells to realize ST, and the substances produced during the process of glucose oxidation can improve the microenvironment for better CDT. Under near-infrared irradiation, the generated heat by the photothermal effect of PDA can not only be applied for PTT but also enhance the catalytic efficiency of Fenton-like reactions and the enzymatic activity of GOx, achieving the goal of trimodal synergistic therapy of CDT/ST/PTT. Importantly, in vivo studies using tumor-bearing mice demonstrate that the combined therapy via Cu-ZnP@GOx/PDA/PEG NPs effectively suppresses tumor growth, and no obvious systemic toxicity can be observed. Taken together, the construction of Cu-ZnP@GOx/PDA/PEG NPs can provide a feasible strategy for a safe and efficient cancer therapy.
