“…4,5 Sometimes, the catalytic effect of the metallic structures can be also advantageous for photocatalytic reactions. 6,7 However, the main topic considering the use of metallic nanostructures in photocatalysis is called plasmonic photocatalysis. The surface plasmon resonance (SPR) phenomenon can be responsible for, e.g., hot charge carrier generation, local electric eld enhancement and, therefore, for the inuence on the photocatalyst's activity.…”

The progress of solar‐driven water‐splitting technology has been impeded by the limited light response capability of semiconductor materials. Despite attempts to leverage nearly 50% of infrared radiation for photothermal synergy and catalytic reaction enhancement, heat loss during liquid phase reactions results in low energy conversion efficiency. Here, the photothermally driven catalytic water‐splitting system, which designs K‐SrTiO3‐loaded TiN silica wool at the water–air interface. Photocatalytic tests and density functional theory calculations demonstrate that the thermal effect transforms liquid water into water vapor, thereby reducing the reaction free energy of catalysts and improving the transmission rate of catalytic products. Hence, the hydrogen evolution rate reaches 275.46 mmol m−2 h−1, and the solar‐to‐hydrogen (STH) efficiency is 1.81% under 1 sun irradiation in this gas–solid system, which is more than twice that of liquid water splitting. This novel photothermal catalytic pathway, which involves a coupled reaction of water evaporation and water splitting, is anticipated to broaden the utilization range of the solar spectrum and significantly enhance the conversion efficiency of STH.

Biomass photoreforming is a promising way of producing sustainable hydrogen thanks to the abundant sources of biomass feedstocks. Solar energy provides the heat and driven force to initial biomass oxidation coupled with H2 evolution. Currently, biomass photoreforming is still far from plant‐scale applications due to the lower solar energy utilization efficiencies, the low H2 yield, and the lack of appropriate photoreactors. The production of H2 from photoreforming of native biomass and platform molecules was summarized and discussed with special attention to the prospects of scaling up the catalysis technology for mass production of hydrogen. The types of photoreforming including photocatalysis and photothermal catalysis were discussed consequently considering the different requirements for photoreactors. We also reviewed the photoreactors that support biomass photoreforming. Numerical simulation methods were implemented for the solid‐liquid two‐phase flow and inter‐particle radiative transfer involved in the reaction process. Developing concentrated photothermal catalytic flowed reactors is beneficial to scale‐up catalytic hydrogen production from biomass.
