Summary: In this study, a near-infrared (NIR) light active heterostructure photocatalyst was constructed by integrating CoP nanorods and CoO nanoplates with a nanosized CdZnS solid solution. The prepared ternary composite exhibited high hydrogen generation activity under real sunlight and high NIR-activity of H2 evolution under single wavelength light of 1020 nm. Various characterizations revealed that the impressive photocatalytic performance was achieved due to the existence of a double heterojunction in this ternary composite. This study provides an idea for constructing efficient photocatalysts with NIR-active performance by employing a photo-thermal antenna and designing appropriate transfer routes for photo-electrons and hot-electrons.

Summary: By pyrolysis of CdZnS solid solution in a polymethyl methacrylate nanoreactor, we successfully constructed a new type of heterostructure consisting of alternate CdS and ZnO grains with good interfaces in the hierarchically periodic macroporous walls. The alternately arranged CdS-ZnO heterojunctions in the macroporous structures led to spatial separation and accumulation of photogenerated electrons and holes, resulting in enhanced carrier utilization. The photocatalytic H2 evolution rate of this CdS-ZnO heterostructure reached 587.8 μmol h-1 without a cocatalyst, demonstrating its high efficiency.

Summary: Integrating a molecular catalyst with a light harvester into a photocatalyst is an effective strategy for solar light conversion. In this study, the heterogenization of a Salen metal complex molecular catalyst into a rigid covalent organic framework (COF) was achieved through covalent linkage with the light-harvesting unit of pyrene for photocatalytic hydrogen evolution. The chemically conjugated bonds between the two units contribute to fast photogenerated electron transfer and promote the proton reduction reaction.

Summary: In this study, a core-shell FeS2@ZnIn2S4 nanomaterial was fabricated with FeS2 as a photothermal substrate to enhance charge migration and reaction system temperature, and the S-scheme interface charge transfer achieved spatial separation of charge carriers. The ZnIn2S4 nanosheet coating on the FeS2 surface effectively prevented heat loss. Under simulated solar irradiation, the optimized H2 production rate of the material reached 5.05 mmol/g/h without the need for Pt as a co-catalyst, which was 47.9 and 53.7 times higher than that of pristine ZnIn2S4 and FeS2, respectively. The hydrogen production tests in simulated seawater demonstrated the excellent environmental adaptability of the material. This study provides a feasible strategy for efficient utilization and conversion of solar energy through a photothermal-assisted S-scheme heterojunction system.

Summary: This study focuses on efficient piezo-photocatalytic hydrogen evolution from water splitting using one-dimensional nanorod-structured CdxZn1-xS solid solutions, simultaneously converting solar and vibration energy. Cd0.4Zn0.6S nanorods exhibit a prominently synergetic piezo-photocatalytic H-2 yield rate under visible light and ultrasound irradiation. The enhanced catalytic activity of Cd0.4Zn0.6S is attributed to strengthened charge separation by piezo-potential, increased strain sensitivity, and optimal combination of piezoelectricity and visible-light response. The research is expected to inspire a new design strategy for efficient renewable fuel production.

Summary: Through ultrafast spectroscopy, it was found that InP/ZnSe/ZnS core/shell/shell quantum dots exhibit better electron transfer capability compared to InP/ZnS quantum dots, as the introduction of ZnSe midshell improves passivation and enhances exciton delocalization. Temperature-dependent PL spectra indicate that the exciton-phonon coupling strength and exciton binding energy of InP/ZnSe/ZnS quantum dots are smaller. Further photocatalytic hydrogen evolution testing shows that InP/ZnSe/ZnS quantum dots have significantly higher photocatalytic activity and improved stability.

Summary: In this study, Cu3SnS4 with S vacancy and different ratios of Cu(I/II) and Sn(II/IV) was designed for photocatalytic CO2 reduction with high selectivity and activity. The conduction band (CB) position dominated by the Sn (II) 5p orbital of Cu3SnS4 could be regulated via controlling the content of Sn(II). The presence of Cu(I) and Sn(IV) in crystal lattice acted as the adsorption sites of CO2 and H2O, promoting further protonation for CH4 generation. The introduction of S vacancy led to the appearance of Cu(I) and Sn(II), inhibiting electron-hole recombination and improving reactivity and selectivity of CH4 production.
