Summary: Carbon materials with different nanostructures and high surface area have emerging applications in electrocatalytic and photocatalytic CO2 utilization. However, the photocatalytic efficiency of pristine carbon is low, so it is usually combined with other materials to increase CO2 absorption and conversion. Carbon-based materials with transition metals and organometallic complexes are commonly used as photocatalysts for CO2 reduction.

Summary: In this study, the enhanced light penetration and mass transfer efficiency of photocatalytic foams for converting CO2 to CO were reported. A metallic foam with uniformly coated photoactive indium oxide hydroxide nanorods was used to evaluate the photochemical and thermochemical reverse water gas shift reaction. The results showed a significantly higher CO production rate through enhanced light penetration and a remarkably high thermochemical CO production rate. It was also demonstrated that using structured supports is critical in scaling up future photocatalytic processes.

Summary: By using CO2 laser irradiation, we successfully prepared chitin nanopaper and investigated its performance in solar thermal heating. The CO2-laser-carbonized chitin nanopaper showed excellent solar thermal heating performance, with an equilibrium surface temperature of 77.7 degrees C, higher than that of commercial nanocarbon films and conventionally carbonized bionanofiber papers. This study paves the way for the high-speed fabrication of carbonized chitin nanofiber materials and their application in solar thermal heating.

Summary: In this study, ZnO nanoparticles were adsorbed on the surface of GO/ZnIn2S4 to obtain high-performance semiconductor photocatalysts. Through the synergistic effect between GO and ZnO/ZnIn2S4 type-II heterojunction, the recombination rate of photogenerated carriers was reduced, and the light absorption performance of the photocatalyst was improved. Experiment results showed that GO/ZnO/ZnIn2S4 exhibited a 5.4 times higher photocatalytic kinetic coefficient for methylene orange compared to pure ZnO, indicating its superior performance among the samples.

Summary: This study designs a ternary nanomaterial structure containing a quaternary chalcogenide nanocomposite to address the deficiencies in poor semiconductor materials for CO2 reduction. The ternary photocatalyst, AgFeNi2S4-Graphene-ZnO, shows high levels of CO2 reduction to methanol due to the improved charge transfer between the components. The stability and recyclability of the photocatalysts were also determined.
