In this paper, we provide an overview of the advanced photocatalytic materials prepared so far that can be activated by sunlight, and their efficiency in H 2 production. . Photocatalytic solar power systems primarily rely on utilizing the complete range of solar spectrum. Current photocatalytic systems achieve solar-to-hydrogen conversion efficiencies of only 1-2% under laboratory conditions, with real-world performance further limited by light absorption. . Photocatalytic hydrogen (H 2) production offers a promising solution to energy shortages and environmental challenges by converting solar energy into chemical energy.
