Summary: Photocatalytic water splitting for hydrogen production has been explored in energy science, but efficiency is often lacking. This study proposes a controlled synthetic strategy to develop concave gold nanorods (Au NRs) with enhanced photocatalytic performance. The concave Au NRs, synthesized in aqueous solution, exhibit high-index facets and unique plasmon resonance modes. By selectively growing Pt nanoparticles and CdS nanocrystals onto the Au NRs, the photocatalytic H2 production rate reaches as high as 21654.56 μmol•g^-^1•h^-^1, demonstrating the great potential of faceted metal nanostructures for efficient photocatalysis.

Summary: Delaminated 2D Ti3C2 MXene nanosheets were used to decorate P-doped tubular g-C3N4, forming a 1D/2D Schottky heterojunction. The optimized composite showed significantly enhanced photocatalytic activity for hydrogen evolution compared to pristine g-C3N4 and PTCN. The enhancement was attributed to the phosphorus doping, unique structure of the heterojunction, and the separation and inhibition of charge carriers. Metallic Ti3C2 acted as an electron sink and photon collector, while the ultrathin Ti3C2 flake served as a co-catalyst for higher reactivity.

Summary: This study investigates the synthesis and characterization of a p-n junction ZnIn2S4/CoFe2O4 and biochar composite photocatalyst, and its photocatalytic activity towards ciprofloxacin under simulated sunlight. The composite exhibits enhanced charge carrier separation, excellent light absorption intensity, and hierarchical porous morphology. The introduction of biochar prevents the agglomeration of nanoparticles and promotes charge carrier mobility. The synergy between biochar adsorption and p-n junction photocatalytic activity greatly improves pho-todegradation performance. The study also explores the effects of coexisting anions and humic acid on the photocatalytic process, and proposes a possible mechanism. Overall, this study provides new insights into the fabrication of recyclable photocatalysts for environmental purification.

Summary: Photocatalytic hydrogen evolution reaction (PC-HER) provides a solution to energy crisis and environmental pollution. The g-C3N4-based van der Waals homojunctions exhibit outstanding PC-HER rates due to the cooperative effects of various factors, such as shortened bandgap, enlarged specific surface area, matched type II energy band structure, and specific vdW structures.

Summary: A series of novel mixed oxides with honeycomb layered structure, including delafossite-type Na3M2SbO6, were successfully synthesized via a facile method. The increased entropy was found to have a significant impact on the Jahn-Teller distortion effect, as evident from XRD/Rietveld structural analysis. The synthesized oxides showed photocatalytic activity, with a decrease in optical band-gap upon increasing the number of elements.
