Summary: In this paper, a hybrid photocatalyst (Ni6/g-C3N4) with excellent photocatalytic hydrogen production activity was successfully synthesized by decorating Ni6(SC2H4Ph)12 nanoclusters on g-C3N4 nanosheets at room temperature. The formation of Ni6/g-C3N4 was attributed to the electrostatic interaction between Ni6 and g-C3N4. The hybrid photocatalyst exhibited significantly enhanced hydrogen production activity compared to pure g-C3N4, with a visible-light hydrogen production rate approximately 290 times higher.

Summary: Here, we present SnS/g-C3N4 crystallized and nanostructured photocatalysts for efficient and selective CO2 conversion to CH4. By engineered thermal evaporation and decoration of g-C3N4 through a simple dipping method, the limitations of bulk SnS-based photocatalysts are overcome. The SnS/g-C3N4 nanostructured photocatalysts achieve a superior methane production rate of 387.5 μmol m-2 h-1 (c.a. 122.33 μmol g-1 h-1) with an apparent quantum yield of c.a. 9.7% at 520 nm with engineered lengths. Moreover, they show 100% selective production toward CH4 and stable operation for over 10 hours.

Summary: SnS and SnS2 are two anode materials with excellent theoretical capacity for Sodium ion batteries. However, their electrochemical performance is affected by volume collapse and low electric charge conductivity. The construction of SnS-SnS2 heterostructures improves conductivity, and compounding with Graphene Oxide (GO) prevents volume effects and enhances cyclic stability and initial coulombic efficiency. Experimental and simulation studies show that SnS-SnS2 @GO composites exhibit superior conductivity, cycle stability, and unique nano-flake structure, making them ideal anode materials for sodium ion batteries.

Summary: A single-atom Ce-targeted regulation strategy was proposed for p-SnS/n-SnS2, which can regulate the amount and size of SnS quantum dots on the surface of SnS2 by doping different amounts of Ce. Sn-S-Ce bonds were formed by combining single-atom Ce with SnS, effectively inhibiting the growth and oxidation of SnS quantum dots. Ce-doped SnS quantum dots served as electronic sensitizers, effectively increasing the carrier concentration in SnS2 due to the unique energy band structure of p-SnS and n-SnS2. The gas sensor based on 1% Ce-doped SnS/SnS2 composites exhibited high sensitivity (with a response of 22.1 to 1 ppm NO2), ultralow detection limit (1 ppb), excellent long-term stability at room temperature, and a lower baseline resistance.

Summary: A multilayer SnS2 material with a palm-fiber-like structure was successfully hydrothermally synthesized by anion exchange process. Compared to monolayer SnS2, the multilayer SnS2 exhibited significant photothermal effect and excellent photocatalytic activity under full solar spectrum. The micron- and nanometer-scale structure of the material led to larger electrochemically active surface area and enhanced absorption for full solar spectrum. The combined effect of UV-vis absorption by the nanoscale primary structure and NIR absorption by the secondary micron-structure played an important role in its superior absorption capability and photocatalytic activity. This work provides a foundation for the development of photocatalysts, photodetectors, solar cells, and other solar energy conversion devices with full solar spectrum light response.

Summary: Rational structure design of semiconductor photocatalysts plays a significant role in enhancing their sunlight-driven hydrogen-evolution performance. In this study, Cd1-xZnxS nanopopcorns with zinc blende/wurtzite phase junctions were synthesized using excess thioacetamide (TAA), showing improved visible-light photocatalytic H-2 evolution activity and a high apparent quantum yield. The results indicate that the Cd1-xZnxS samples with excess TAA not only enhance light absorption and hydrophilicity, but also promote the separation and migration of photoinduced electron-hole pairs due to the presence of type-II ZB/WZ phase junctions.
