The process of Photocatalytic Hydrogen Evolution (PHE) represents a reliable method for addressing the energy crisis. In this work, a self-assembly method was performed to combine 2D NiPS 3 (NPS) nanosheets (Ns) with 2D CN Ns to prepare NPS Ns/CN Ns (NPCN) 2D/2D heterojunctions with intimately interfacial contact between these two components. Compared to CN Ns, NPCN photocatalysts possess wide-spectrum light absorption regions, excellent light-to-thermal energy effect, electron mobility, charges transfer, and abundant surface active site, thus leading to the enhanced PHE performance for NPCN composites in natural seawater and simulated seawater. Meanwhile, the negative effect of the added various ions on the PHE performance was revealed over 2-NPCN using different typical aqueous solutions. The first-principle calculations and experimental analysis were performed to gain a deep understanding of the underlying mechanisms responsible for the exceptional HER activity over NPCN composites. Drawing from the characterization and DFT calculation results, a photothermal-assisted PHE mechanism was proposed over NPCN composites. This work provides a strategy for the design and synthesis of efficient, stable and highly active g-C 3 N 4 -based heterojunctions.

Photothermal-assisted photocatalytic hydrogen production is a very promising way to maximize solar energy utilization to obtain clean energy. Herein, we designed a composite photocatalyst with coating core-shell Fe 3 O 4 @SiO 2 nanoparticles on the surface of ZnIn 2 S 4 micro-flowers for high-efficient photothermal-assisted photocatalytic water/seawater splitting. Experimental results reveal that in the core-shell structure of Fe 3 O 4 @SiO 2 , the addition of the SiO 2 shell in Fe 3 O 4 @SiO 2 not only separates the photothermal and photochemical components, avoiding competition between them, but also further increases the temperature of the core in a manner similar to the greenhouse effect , which was used as a hot core to provide heat to the ZnIn 2 S 4 photocatalyst to increase the surface reaction temperature and enhance the collision chances of photo-generated carriers into causing severe recombination of carriers, thus promoting the hydrogen generation. Significantly, the optimal photocatalytic water/seawater splitting into hydrogen production rates over Fe 3 O 4 @SiO 2 /ZnIn 2 S 4 are up to 1258.5 and 1108.5 μmol g -1 h −1 , which are 11.9 and 14.7 times higher than that of pristine ZnIn 2 S 4 , respectively. This study provides an idea for the design of highly efficient photothermal-assisted photocatalysts.

Photocatalytic water splitting on noble metal-free photocatalysts for H 2 generation is a promising but challenging approach to realize solar-to-chemical energy conversion. In this study, Mo/Mo 2 C nanoparticles anchored carbon layer (Mo/Mo 2 C@C) was obtained by a one-step in-situ phase transition approach and developed for the first time as a photothermal cocatalyst to enhance the activity of ZnIn 2 S 4 photocatalyst. Mo/Mo 2 C@C nanosheet exhibits strong absorption in the full spectrum region and excellent photo-thermal conversion ability, which generates heat to improve the reaction temperature and accelerate the reaction kinetics. Moreover, metallic Mo/Mo 2 C@C couples with ZnIn 2 S 4 to form ZnIn 2 S 4 –Mo/Mo 2 C@C Schottky junction (denoted as ZMM), which prevents the electrons back transfer and restrains the charge recombination. In addition, conductive carbon with strong interfacial interaction serves as a fast charge transport bridge. Consequently, the optimized ZMM-0.2 junction exhibits an H 2 evolution rate of 1031.07 μmol g −1 h −1 , which is 41 and 4.3 times higher than bare ZnIn 2 S 4 and ZnIn 2 S 4 –Mo 2 C, respectively. By designing novel photothermal cocatalysts, our work will provide a new guidance for designing efficient photocatalysts.

A highly permeable thin-film composite (TFC) polyamide membrane with efficient salt rejection is valuable for numerous industrial processes. To achieve this objective, it is essential to innovate the membrane fabrication process to produce an ultrathin polyamide separation layer. In this study, a photothermal-assisted interfacial polymerization (IP) strategy was proposed to fabricate TFC polyamide membranes by incorporating carboxylated carbon nanotubes (CNTs) with exceptional photothermal properties. CNTs absorb solar energy and convert it into heat, significantly elevating the temperature in their microregions, thereby accelerating the reaction between m-phenylenediamine (MPD) and trimesoyl chloride (TMC) during the IP process. Exploiting the self-inhibition characteristics of IP, the preformed polyamide layer suppresses the subsequent diffusion of MPD into the reaction interface, resulting in the formation of an ultrathin polyamide layer. Consequently, the CNTs-modified polyamide membrane with photothermal assistance obtains a thickness of approximately 94 nm, significantly thinner than the control membrane (189 nm). Furthermore, it demonstrates a superior water flux of 54.4 L m–2 h–1, higher than that of the pristine TFC membrane without CNTs and the conventional CNTs-modified membrane, while maintaining a NaCl rejection of ∼96%. The photothermal-assisted IP strategy provides some inspiration for engineering high-performance polyamide membranes available in various advanced separations.

Crude oil spills pose serious challenges due to low fluidity and high viscosity. Researchers are exploring a range of sustainable cleanup solutions, such as using heating components to reduce oil viscosity. Herein, an electroless plating technique was adopted for depositing copper sulfide (CuS) on a polyurethane (PU) sponge by a coordination strategy. Subsequently, a layer of octadecyltrichlorosilane (OTS) was deposited to enhance the surface oil absorption ability. The PU@OTS-CuS sponge has demonstrated superhydrophobicity and remarkable oil absorption capability ranging from 11.5 to 47 g/g for oils with diverse viscosities. Moreover, it has sustained its 22.5 g/g oil absorption capacity for lubricant oils and separation efficiency of over 97% for the n-hexane and dichloromethane–water mixture even after undergoing 10 cycles. The surface temperature of the modified sponge was increased to 74 °C within 180 s under 1 sun irradiation and a sustained crude oil absorption capacity of 20 g/g even after 10 cycles. In continuous crude oil remediation, the modified sponge collected 3.257 g within 15 min at a rate of 0.542 g/min. Additionally, the modified sponge revealed superior stability against immersion in seawater and different pH solutions, exposure to UV light, sand abrasion, mechanical compression, and cyclic photothermal performance. This research presents a new strategy for depositing a photothermal component on sponge surfaces to improve crude oil cleanup.

Advanced oxidation processes (AOPs) based on photo-Fenton reaction has been widely used in refractory organic wastewater treatment . However, the mineralization rate and H 2 O 2 utilization in AOPs is relatively low. Herein, a photothermal-assisted photocatalytic-Fenton-like process with CuO x /γ-Al 2 O 3 catalyst was designed to solve the above issues. The utilization rate of H 2 O 2 and mineralization rate of tetracycline hydrochloride (TC) in the 3%-CuO x /γ-Al 2 O 3 /H 2 O 2 /full spectrum light system were significantly increased to 72.0% and 74.3%, respectively, which were ascribed to the synergy of photothermal effect and photocatalytic-Fenton-like reaction. During the simultaneous removal of TC and Cr(VI), the reaction efficiency of 3%-CuO x /γ-Al 2 O 3 /H 2 O 2 /light system was much higher than that of 3%-CuO x /γ-Al 2 O 3 /H 2 O 2 system. In addition, the 3%-CuO x /γ-Al 2 O 3 /H 2 O 2 /light system was not only active in wider pH range (3–9), but also effective in various organic pollutants and Cr(VI) coexisted solutions as well as different water conditions. More importantly, a possible photothermal-assisted photocatalytic-Fenton-like reaction mechanism for the simultaneous removal of TC and Cr(VI) in the CuO x /γ-Al 2 O 3 /H 2 O 2 /light system was proposed. This work may pave a new way for efficient simultaneous removal of refractory organic pollutants and heavy metals in wastewater.

Frequent oil spills at sea and the large-scale marine fires caused by them seriously jeopardize the marine ecosystem and human health. In this study, the use of multifunctional oil-absorbing materials was expected to solve the problems triggered by marine oil spills. Herein, a multifunctional coated polyurethane foams (FPMA-PUF) were prepared by immersing polyurethane foams (PUF) into a coating containing fluorinated polydimethylsilane (F-PDMS), silica, hydroxylated multi-walled carbon nanotubes (MWCNTs-OH), and ammonium polyphosphate (APP). The results showed that FPMA-PUF exhibited superhydrophobicity, chemical stability, and mechanical durability, which was capable of adsorbing and separating a variety of oils in a stable manner. FPMA-PUF had excellent flame retardancy and self-extinguishing after 65 s of combustion, which could reduce the risk of fire. In addition, FPMA-PUF also had a certain degree of fire resistance in the simulation of marine oil fire. FPMA-PUF could be used in combination with a pump to achieve the recovery of oil within 52 s for fire extinguish. This work provided a new direction for dealing with the adsorption and separation of high-viscosity oils, safety prevention and control of fires caused by marine oils, as well as fire extinguishing treatment, and realizing the benign strategy of extinguishing the fire by pumping the oil strike at the root of the trouble.

Against the backdrop of energy shortage, hydrogen energy has attracted much attention as a green and clean energy source. In order to explore efficient hydrogen production pathways, we designed a composite photocatalyst with carbon-based core-shell photothermal-assisted photocatalytic system (Carbon@ZnIn 2 S 4 , denoted as C@ZIS). The well-designed catalyst C@ZIS composites demonstrated a photocatalytic hydrogen precipitation rate of 2.97 mmol g -1 h −1 even in the absence of the noble metal Pt co-catalyst. The incorporation of carbon-based core-shell photocatalysts into a photocatalytic reaction significantly affects the activity of the reaction by triggering a photothermal effect in the reaction solution. The results of the physicochemical experiments demonstrated that the carbon spheres in C@ZIS composite system could provide a greater number of active sites, thereby accelerating the electron transfer and separation efficiency, and thus enhancing the photocatalytic activity. The study presents an efficacious design concept for the development of efficacious carbon-based core-shell photothermal-assisted photocatalysts, which is anticipated to facilitate the efficient conversion of solar energy to hydrogen energy.

Integrating anodic biomass valorization with carbon dioxide electroreduction (CO2RR) can produce value-added chemicals on both the cathode and anode; however, anodic oxidation still suffers from high overpotential. Herein, a photothermal-assisted method was developed to reduce the potential of 5-hydroxymethyl furfural (HMF) electrooxidation. Capitalizing on the copious oxygen vacancies, defective Co3O4 (D-Co3O4) exhibited a stronger photothermal effect, delivering a local temperature of 175.47 oC under near infrared light illumination. The photothermal assistance decreased the oxidation potential of HMF from 1.7 V over pristine Co3O4 to 1.37 V over D-Co3O4 to achieve a target current density of 30 mA cm-2, with 2,5-furandicarboxylic acid as the primary product. Mechanistic analysis disclosed that the photothermal effect did not change the HMF oxidation route but greatly enhanced the adsorption capacity of HMF. Meanwhile, faster electron transfer for direct HMF oxidation and the surface conversion to cobalt (oxy)hydroxide, which contributed to indirect HMF oxidation, was observed. Thus, rapid HMF conversion was realized, as evidenced by in situ surface-enhanced infrared spectroscopy. Upon coupling cathodic CO2RR with an atomically dispersed Ni-N/C catalyst, the Faradaic efficiencies of CO (cathode) and 2,5-furandicarboxylic acid (FDCA, anode) exceeded 90.0% under a low cell potential of 1.77 V.

Bacteria-driven drug-delivery systems have attracted great attention for their enhanced therapeutic specificity and efficacy in cancer treatment. YB1, a particularly attractive genetically modified safe Salmonella Typhimurium strain, is known to penetrate hypoxic tumor cores with its self-driven properties while remarkably avoiding damage to normal tissues. Herein, nanophotosensitizers (indocyanine green (ICG)-loaded nanoparticles , INPs) were covalently attached to the surface of YB1 with amide bonds to develop a biotic/abiotic cross-linked system (YB1-INPs) for tumor precision therapy. YB1 microswimmer retained its viability after efficiently linking with INPs. This YB1-INPs treatment strategy demonstrated specific hypoxia targeting to solid tumors, perfect photothermal conversion, and efficient fluorescence (FL) imaging properties. Benefited from the combined contribution of tumor tissue destruction and the bacteria-attracting nutrients generation after photothermal treatment, the bioaccumulation of YB1-INPs was significantly improved 14-fold compared to no photothermal intervention. Furthermore, YB1-INPs pervaded throughout the large solid tumor (≥500 mm 3 ). Under near-infrared (NIR) laser irradiation, YB1-INPs exhibited a dependable and highly efficient photothermal killing ability for eradicating the large solid tumor without relapse. This strategy of bacteria-driven hypoxia-targeting delivery has a great value for large solid tumors therapy with low toxicity and high efficiency.

Photocatalysis is appealing in removing trace NO, but its efficacy is often deteriorated by H 2 O, which is ubiquitous in environment, and how to resolve this issue and elucidate the underlying mechanisms at the molecular-level are challenging. Herein, we report a full-spectrum Bi/Bi 4 Ti 3 O 12 catalyst modified with Bi-O vacancy associates via a steam-assisted chemical reduction process. The optimized structure demonstrates NO removal efficiency of 75.5 %, four times over its counterpart, Bi 4 Ti 3 O 12 (37.9 %). Based on positron annihilation spectra and theoretical studies, the enhanced activity is induced by Bi-O vacancy associates, which not only optimizes the photogenerated carrier dynamical behaviors but lowers the energy barriers for photocatalytic oxidation of NO. Importantly, the photothermal activity of the optimal sample exhibited a decline from 76.7 % (0 % RH) to 71.2 % (100 % RH), whereas its photoactivity (20°C) demonstrated a more pronounced decrease, dropping from 60.1 % (0 % RH) to 41.2 % (100 % RH). Therefore, humidity-resistant performance over the optimal sample is attributed to photothermal effect induced by in-situ precipitated Bi and multiple defects. Furthermore, the results of adsorption and desorption behavior of H 2 O and in situ DRIFTS suggest the photothermal-assisted desorption of surface-bound H 2 O can suppress the interactions of H 2 O and stable bidentate nitrate ( bi -NO 3 ⁻) by hydrogen bonds to generate monodentate nitrate ( m -NO 3 ⁻), thereby hindering the photodecomposition of m -NO 3 ⁻ to NO/NO 2 . This work elucidates the significance of photothermal effect in developing efficient photocatalyst for atmospheric NO purification in humid conditions.

Untethered capsules hold clinical potential for the diagnosis and treatment of gastrointestinal diseases. Although considerable progress has been achieved recently in this field, the constraints imposed by the narrow spatial structure of the capsule and complex gastrointestinal tract environment cause many open-ended problems, such as poor active motion and limited medical functions. In this work, we describe the development of small-scale magnetically driven capsules with a distinct magnetic soft valve made of dual-layer ferromagnetic soft composite films. A core technological advancement achieved is the flexible opening and closing of the magnetic soft valve by using the competitive interactions between magnetic gradient force and magnetic torque, laying the foundation for the functional integration of both drug release and sampling. Meanwhile, we propose a magnetic actuation strategy based on multi-frequency response control and demonstrate that it can achieve effective decoupled regulation of the capsule’s global motion and local responses. Finally, through a comprehensive approach encompassing ideal models, animal ex vivo models, and in vivo assessment, we demonstrate the versatility of the developed magnetic capsules and their multiple potential applications in the biomedical field, such as targeted drug delivery and sampling, selective dual-drug release, and light/thermal-assisted therapy.
