Solar-driven flat-panel HO-to-H conversion is an important technology for value-added solar fuel production. However, most frequently used particulate photocatalysts are hard to achieve stable photocatalysis in flat-panel reaction module due to the influence of mechanical shear force. Herein, a highly active CdS@SiO-Pt composite with rapid CdS-to-Pt electron transfer and restrained photoexciton recombination was prepared to process into an organic-inorganic membrane by compounding with polyvinylidene fluoride (PVDF). This PVDF networked organic-inorganic membrane displays high photostability and excellent operability, achieving improved simulated sunlight-driven alkaline HO-to-H conversion activity (213.48 mmol m h) following a 0.68% of solar-to-hydrogen efficiency. No obvious variation in its appearance and micromorphology was observed even being recycled for 50-times, which considerably outperforms the existing membrane photocatalysts. Subsequently, a homemade panel HO-to-H conversion system was fabricated to obtain a 0.05% of solar-to-hydrogen efficiency. In this study, we opens up a prospect for practical application of photocatalysis technology.

To enable highly efficient in situ hydrogen release from methanol/water reforming at lower temperature, the integration of solar-energy offers a promising approach to activate methanol/water and substantially lower the activation energy of this reaction. Herein, we present a novel dual-vacancy defective hollow heterostructure derived from Metal-Organic Frameworks, featuring abundant surface hydroxyl groups and S/O vacancies, for photothermal-promoted methanol solution reforming into hydrogen. The [In2S3-x/In2O3-x](OH)y exhibits exceptional photothermal H2 evolution activity, achieving a production rate of 215.

With growing environmental concerns and the need for sustainable energy, multifunctional materials that can simultaneously address water treatment and clean energy production are in high demand. In this study, we developed a cost-effective method to synthesize zinc oxide (ZnO) nanowires via the anodic oxidation of zinc foil. By carefully controlling the anodization time, we optimized the Zn/ZnO-5 min electrode to achieve impressive dual-function performance in terms of effective photoelectrocatalysis for water splitting and waste water treatment.

Solar-driven photocatalytic water splitting offers a sustainable pathway to produce green hydrogen, yet its practical application encounters several challenges including inefficient photocatalysts, sluggish water oxidation, severe reverse reactions and the necessity of separating produced hydrogen and oxygen gases. Herein, we design and develop a photocatalytic system composed of two separate reaction parts: a hydrogen evolution cell containing halide perovskite photocatalysts (MoSe-loaded CH(NH)PbBrI) and an oxygen evolution cell containing NiFe-layered double hydroxide modified BiVO photocatalysts. These components are bridged by a I/I redox couple to facilitate electron transfer, realizing efficient overall water splitting with a solar-to-hydrogen conversion efficiency of 2.

Efficient charge separation at the semiconductor/cocatalyst interface is crucial for high-performance photoelectrodes, as it directly influences the availability of surface charges for solar water oxidation. However, establishing strong molecular-level connections between these interfaces to achieve superior interfacial quality presents significant challenges. This study introduces an innovative electrochemical etching method that generates a high concentration of oxygen vacancy sites on BiVO surfaces (Ov-BiVO), enabling interactions with the oxygen-rich ligands of MIL-101.

Photocatalytic overall water splitting is a promising approach for a sustainable hydrogen provision using solar energy. For sufficient solar energy utilization, this reaction ought to be operated based on visible-light-active semiconductors, which is very challenging. In this work, an F-expedited nitridation strategy is applied to modify the wide-bandgap semiconductor SrTiO for visible-light-driven photocatalytic overall water splitting.
