Monolithic inverse catalysts were fabricated by optimizing treatment conditions. • O V generation could be significantly promoted by optimizing inverse structure. • Alternating magnetic field could enhance charge transfer across inverse interface. • Magnetocatalytic oxidation required lower temperatures than traditional heating. • Magnetocatalytic purification encompassed demands of intermittent VOCs source. Catalytic oxidation is widely employed in volatile organic compounds (VOCs) degradation. The continuous optimization of catalytic oxidation technology encompasses the materials design and heat sources innovations. Herein, we found that adjusting the temperature and H 2 treatment could regulate inverse structure of CoO x /Ni foam (CoO x /NF) monolithic catalysts, resulting in enhancement of oxygen vacancies generation. This promotional effect could be further amplified by electromagnetic induction heating (EMIH), which was probably ascribed to the acceleration of charge transfer across the inverse interface induced by alternating magnetic field. Consequently, CoO x /NF-300R, as an inverse catalyst synthesized under optimized conditions, could exhibit superior activity for catalytic oxidation of VOCs including benzene, toluene and o -xylene. The demanded temperature for removal of toluene in EMIH mode was reduced by approximately 50°C compared to that in traditional heating mode. Furthermore, the VOCs catalytic oxidation system composed of CoO x /NF-300R and electromagnetic induction could meet the requirements for rapid and efficient purification of multi-species and intermittent pollution sources.

One-step flotation–activation for CGFS-derived catalysts. • Ni- and K-modified catalysts show distinct reforming pathways. • Ni-based catalysts achieve high tar conversion (97.2%) with coke resistance. • K favors CH 4 formation while Ni enhances H 2 -rich syngas production. Efficient and stable catalysts are essential for biomass-tar reforming in sustainable biomass gasification systems that utilize low-cost solid waste feedstocks. In this study, coal gasification fine slag (CGFS) was processed by saline flotation to enrich the residual carbon fraction and remove ash content, yielding a support material with enhanced catalyst surface area and pore volume. Low-concentration saline flotation produced supports with greater specific surface areas (S BET ), while high-concentration saline flotation yielded catalysts with superior catalytic performance. Catalytic performance was primarily determined by the nature of the metal loading. Ni-loaded catalysts (Ni4) achieved higher tar-conversion rates and CO yields than K-loaded counterparts (K4), with substantially greater H 2 production. Conversely, K4 produced higher CH 4 yields than Ni4, attributable to enhanced high-temperature methanation leading to higher CH 4 selectivity, whereas Ni-based catalysts showed superior overall catalytic performance and anti-coking ability, attributable to their unique FeNi 3 alloy active centers. Furthermore, regeneration tests demonstrated that both Ni4 and K4 catalysts retained considerable tar conversion capability after three reaction–regeneration cycles, highlighting their potential for cyclic utilization. These results demonstrate the potential of CGFS as a low-cost tar conversion catalyst. Download: Download high-res image (462KB) Download: Download full-size image

In this work, a binder-free, self-supported Ni–In₂O₃ heterostructured electrode was constructed on three-dimensional Cu foam for the non-enzymatic electrochemical detection of H₂O₂ under near-neutral conditions. In₂O₃ was conformally grown on Cu foam through a solvothermal process followed by calcination, and Ni species were then introduced by electrodeposition to form a Ni-containing/In₂O₃ composite coating with close interfacial contact and a hierarchically rough surface. Owing to its reduced charge-transfer resistance and enlarged electrochemically accessible surface, the Ni–In₂O₃/Cu foam electrode exhibited a sensitive amperometric response toward H₂O₂ reduction in 0.1 M PBS (pH 7.4) at −0.60 V vs. SCE. Two linear ranges were obtained, from 0.6 μM to 1.759 mM and from 2.059 to 9.059 mM, with corresponding sensitivities of 18.492 and 9.799 μA·mM −1 ·cm −2 , respectively, and a detection limit of 0.228 μM (S/N = 3). The sensor also exhibited good anti-interference performance, acceptable repeatability and reproducibility, and stable performance over 25 days. In standard-addition analyses of milk, tap water, and fetal bovine serum, recoveries ranged from 99.3% to 104.7%, with low RSD values (0.07%–3.25%), and Student's t -test revealed no significant difference between the measured and nominal concentrations ( p > 0.05). Moreover, cytocompatibility evaluation and in situ monitoring of H₂O₂ released from PMA-stimulated cells demonstrated its potential applicability in cell-related redox analysis. These results demonstrate that the proposed Ni–In₂O₃/Cu foam electrode is a promising platform for sensitive, reliable, and practical H₂O₂ sensing under near-neutral conditions.

The upcycling of thermoset epoxy resins remains challenging due to their highly cross-linked and chemically inert network structures. Herein, an efficient catalytic hydrodeoxygenation (HDO) route is developed for the direct conversion of bisphenol A-based epoxy resin into aviation-fuel-range cycloalkanes over Ni/HZSM-5 catalyst. Under mild conditions (220 °C, 4 MPa H2), the optimized 15Ni/HZSM-5(360) catalyst achieves a total cycloalkane yield of 92.4%, with the C15 dicycloalkane propane-2,2-diyldicyclohexane accounting for 78.5%. Systematic tuning of Ni loading and support acidity reveals that a balanced interplay between Ni hydrogenation sites and moderated Brønsted acidity is essential for promoting selective C–O bond scission while suppressing excessive C–C bond scission. Time-dependent product analysis suggests C15 cycloalcohols as key intermediates, elucidating a stepwise depolymerization and HDO pathway. Combined techno-economic analysis and life-cycle assessment further demonstrate the economic competitiveness and environmental viability of this catalytic strategy for epoxy resin waste valorization.

Transition metal borides (TMBs) are considered promising electrocatalysts for alkaline hydrogen evolution reaction (HER), but their potential has not been effectively utilized due to their inherent activity and challenges in fine morphology regulation during chemical/electrochemical deposition processes. Here, we prepared Zn incorporated NiB catalyst (NZB) on nickel foam by a simple one-step chemical deposition combined with local dealloying method. It was revealed that Zn incorporation plays a multifunctional role in the activity and stability of NZB catalysts towards alkaline HER. The partial leaching of Zn regulated the microstructure of the NZB, while residual Zn optimized the electronic structure of the NZB catalyst, improving the interaction between the catalyst and HER intermediates, thereby simultaneously increasing the number of active sites and intrinsic activity. Furthermore, we found the introduction of Zn accelerated the completion of surface reconstruction and improved the crystallinity of catalysts, resulting in enhanced chemical and mechanical stability. These findings provide key insights into maximizing the potential of transition metal-based catalysts for HER.

Hydrogenation of pyridines is particularly challenging because their strong coordination to metal sites hinders hydrogen adsorption and can poison the catalysts. Here we show that Ni nanoparticles (NPs) within zeolite crystals can overcome this problem, owing to a network of micropores that features a greater proportion of free Ni sites for hydrogen adsorption even in the presence of pyridines. As a result, a high activity was achieved under mild conditions, substantially outperforming those of the commercial Raney Ni and conventional supported Ni catalysts. In addition, Ni leaching from the Ni NPs within the zeolite crystals was effectively hindered under the reaction conditions, achieving excellent stability. The versatility of the approach was shown by synthesizing Pd NP analogues, which showed improved activity compared with the conventional supported Pd catalysts.

2D-Ga 2 O 3 nanosheets sterically hinder pore entry for targeted Ga distribution. • NiGaSi shows superior activity and drastically reduced carbon deposition. • In-situ DRIFTS identifies carbonyls as key reactive intermediates. • Ga promotes CH 4 activation and inhibits coke formation via isolation effect. Dry reforming of methane (DRM) over Ni-based catalysts suffers from severe coking. We propose a spatially-selective Ga alloying strategy using trace 2D-Ga 2 O 3 to modify external Ni sites. The 2D-Ga 2 O 3 nanosheets, fabricated by air bubbling, are geometrically hindered from entering catalyst pores, enabling targeted surface distribution. After reduction, NiGa alloy forms and dilutes surface Ni ensembles to suppress carbon formation. NiGaSi achieves ∼54% CO 2 and ∼40% CH 4 conversions at 700°C, with only 14.8 wt% coke after 10 h versus 69.8 wt% for NiSi. In-situ DRIFTS identifies carbonyls as reactive intermediates with CH 4 cleavage as the rate-limiting step, while Ga donation promotes CH 4 activation. This morphology-enabled spatial design strategy offers a route for precise catalyst engineering.

Nanoporous high-entropy alloys (HEAs) are emerging as promising electrocatalysts due to their distinctive properties. Surface engineering is an efficient strategy for the further advancement of hydrogen evolution reaction (HER) electrocatalysts. Herein, a maze-like nanoporous CoCrFeNiAl HEA (NPCCF) with fine ligament sizes of ∼17 nm was fabricated using a selective phase dealloying strategy. Compared with commercial thick-ligament porous nickel foam (NF) and as-spun CoCrFeNiAl ribbon, NPCCF, with its nanoscale ligament 3D porosity, possesses a larger electrochemical surface area and exhibits better HER performance. Afterwards, Ni amorphous/crystalline nanoparticles (Ni NPs) with diameters of ∼100 nm were decorated on the NPCCF via a facile electrodeposition method, resulting in a composite electrocatalyst (NPCCF@Ni) designed to boost the HER process. Electrochemical measurements showed that NPCCF@Ni exhibited a low overpotential of 50 mV at a current density of 10 mA cm–2 for HER in 1.0 M KOH. The excellent catalytic activity is attributed to the large active surface area and fast electron transfer ability of the maze-like 3D nanoporous structure decorated with Ni NPs. Theoretical calculations demonstrated that the Ni atoms modified on the CoCrFe model provided a synergistic effect, altering the electronic structure to optimize the adsorption/desorption energy of adsorbed hydrogen (H*) and reduce the reaction energy barrier of the HER process, resulting in lower Gibbs free energy (ΔGH*). This work explores the advantages of nanoporous HEAs as electrocatalysts and provides insights into the design of HER catalysts with excellent performance through surface modification strategies.

Electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) into 2,5-furandicarboxylate (FDCA) has attracted great attention due to its potential for producing degradable plastics. But, HMF electrooxidation still faces challenges such as high overpotentials and sluggish kinetics. Meanwhile, H2 evolution at the cathode is less cost-effective than cathodic reactions producing valuable chemicals. In view of this, a MOF-derived CoFeP cube anchored on rGO-encapsulated nickel foam (NF) via a facile wet-chemical method is reported. The CoFeP–rGO catalyst delivers a low potential of 1.38 V at a current density of 100 mA cm−2 in 1 M KOH containing 10 mM HMF, achieving ∼100% conversion, a 96% yield of FDCA, and 100% Faraday efficiency (FE). It acts as a bifunctional catalyst, demonstrating electrocatalytic reduction of nitrobenzene (NB) at low overpotential with 91% conversion. In the proposed mechanism, the CoFeP–rGO interface is proved to play a crucial role in increasing the catalytic activity via promoting dispersion of the CoFeP nanocrystals on the substrate and accelerating the electron transfer rate across the interface.

This work developed an ultrasonically assisted synthesis of nickel cobaltite (NiCo 2 O 4 ) modified electrode for simultaneous detection of Furazolidone (FRZ) and Metronidazole (MTR) in biological samples. The structural and chemical properties of the as-prepared electrodes were systematically characterized through multiple analytical techniques. The NiCo 2 O 4 -modified glassy carbon electrode (NiCo 2 O 4 /GCE) demonstrated exceptional performance with wide linear ranges of 0.005–200 μM for MTR and 0.01–150 μM for FRZ, with remarkably low detection limits of 2.57 nM and 29.13 nM, respectively. The sensor exhibited excellent selectivity against common interferents, good reproducibility, and maintained > 90 % activity after 30 days. NiCo 2 O 4 /GCE can be used to detect MTR and FRZ in real pharmaceutical and serum samples, achieving excellent recovery rates within the range of 94.0 % to 114.0 %. This work not only presents a superior sensing platform for antibiotic monitoring but also establishes ultrasound-assisted synthesis as an effective strategy for developing advanced bimetallic oxide electrocatalysts.

The direct upgrading of biomass-derived aqueous ethanol to produce long-chain alcohols is important due to the growing demand for value-added sustainable fine chemicals and liquid fuel. In this work, a bimetallic Ni@C catalyst was synthesized by using a facile sol–gel method with bismuth (Bi) doping. The bimetallic NiBi-1/1@C catalyst exhibited distinct advantages in forming C6+ high-carbon alcohols and inhibiting C1 byproducts compared with the monometallic Ni@C. Optimally, an ethanol conversion up to 87.2% with a C6+ alcohol selectivity of 79.9% was demonstrated and the C1 byproduct selectivity was suppressed to 10.1%. The doping of Bi modulates the adsorption of aldehydes on the Ni site, which inhibits the C–C cleavage side reaction, thus realizing the direct and efficient conversion of an ethanol solution to C6+ alcohols. These findings provide a promising strategy for directly converting biomass-derived ethanol to sustainable high-carbon alcohols and biofuel precursors.

Dry reforming of methane (DRM) reaction has attracted much attention due to its important implications for the environment and energy. The nonprecious metallic nickel is a promising active metal in DRM catalysts because of its low price and high activity. However, nickel-based catalysts are prone to deactivation due to sintering and carbon deposition, which is the main factor limiting the industrial application of the DRM reaction. Herein, a highly stable DRM catalyst has been developed, which was a highly dispersed nickel-based catalyst Ni/N-C-DS (Ni supported on N–C support prepared by the double-solvent (DS) method), prepared by impregnating Ni2+ into the cavities of ZIF-8 using the double-solvent method (DS), followed by a one-step carbonization process. The results showed that the Ni/N-C-DS catalyst exhibited smaller metallic Ni nanoparticles, more dispersed Ni species, and richer pore structures. At a reaction temperature of 800 °C, the Ni/N-C-DS catalyst exhibited satisfactory DRM catalytic activity and stability, with CH4 and CO2 conversion rates reaching 82 and 85%, respectively. The H2/CO ratio approached 1, and no deactivation was observed during 300 h of continuous operation. A thorough study of the catalyst’s structure–activity relationship revealed that the high dispersion of Ni0 in the Ni/N-C-DS catalyst was the main source of high activity for the DRM reaction, while the high stability in the later stage (80–300 h) of the DRM reaction was mainly attributed to the synergistic effect between the in situ reduced Ni0 and the initially highly dispersed Ni0.
