“…Hydrogen (H 2 ), as one of the most convenient and reliable energy sources, can be produced and consumed in a green manner, making it an ideal candidate for energy applications. The production of green hydrogen mainly involves generating it by splitting water molecules using suitable electrocatalysts, photocatalysts, or photoelectrocatalysts. − These systems, with their own advantages and limitations, demonstrate the feasibility of electrocatalytic H 2 production for large-scale implementation, which is already being practiced worldwide. However, electrocatalytic H 2 production currently accounts for only less than 5–10% of the total hydrogen production worldwide .…”

Semiconductor photocatalysis has attracted a wide attention for its outstanding capacity on water purification and energy conversion. Herein, a noble-metal-free nanoheterojunction by planting zero-dimensional (0D) CdS nanograins with 10-20 nm in size on the surface of 2D SnS2 nanosheets (NSs) has been created using an in-situ chemical bathing deposition process, where SnS2 NSs have the average diameters of 400 nm as well as thicknesses of less than 20 nm. The possible formation mechanism of CdS/SnS2 (CS/SS) heterogeneous nanostructure is elaborated. The catalytic activities over CS/SS nanocomposites for the photodegradation of organic dye and hydrogen evolution from photolysis water splitting are examined under visible light irradiation. The apparent rate constant (k) of the optimal CS/SS-3 composite in decontamination of methylene blue (MB) is up to 3.34 and 1.87 times as high as that of pristine SnS2 and pure CdS counterparts, respectively. Consistently, the optimized CS/SS-3 sample achieves the highest photocatalytic hydrogen production rate, being 10.3 and 5.7 folds higher than that of solo SnS2 and CdS panels, respectively. The boosted photocatalytic capacities of CdS/SnS2 heterostructures is essentially attributed to the formation of the closely interfacial incorporation between CdS and SnS2 semiconductors, resulting in the effective charge transportation and spatial separation for the photoinduced electron-hole pairs. Furthermore, the traditional type-II charge transfer pathway is proposed based on the perfect band structure and the free radical experiment results.

Hydrogen (H2) has emerged as a clean and versatile energy carrier to power a carbon‐neutral economy for the post‐fossil era. Hydrogen generation from low‐cost and renewable biomass by virtually inexhaustible solar energy presents an innovative strategy to process organic solid waste, combat the energy crisis, and achieve carbon neutrality. Herein, the progress and breakthroughs in solar‐powered H2 production from biomass are reviewed. The basic principles of solar‐driven H2 generation from biomass are first introduced for a better understanding of the reaction mechanism. Next, the merits and shortcomings of various semiconductors and cocatalysts are summarized, and the strategies for addressing the related issues are also elaborated. Then, various bio‐based feedstocks for solar‐driven H2 production are reviewed with an emphasis on the effect of photocatalysts and catalytic systems on performance. Of note, the concurrent generation of value‐added chemicals from biomass reforming is emphasized as well. Meanwhile, the emerging photo‐thermal coupling strategy that shows a grand prospect for maximally utilizing the entire solar energy spectrum is also discussed. Further, the direct utilization of hydrogen from biomass as a green reductant for producing value‐added chemicals via organic reactions is also highlighted. Finally, the challenges and perspectives of photoreforming biomass toward hydrogen are envisioned.
