Experts in nano-scale chemistry have made significant progress in the development of sustainable hydrogen generation from water using solar power. A collaborative study led by Flinders University, in partnership with researchers from South Australia, the US, and Germany, has identified a novel solar cell process for photocatalytic water splitting to produce green hydrogen. The research highlights a 'core and shell Sn(II)-perovskite' oxide solar material as a potential catalyst for the oxygen evolution reaction in hydrogen production. Published in a peer-reviewed journal, the study’s results show promise for advancing 'green' hydrogen technologies with efficient electrolysis. Solar-driven processes utilizing sunlight for hydrogen production are seen as a potential alternative for large-scale industrial hydrogen generation. The development of cost-effective, high-performance perovskite generation systems is a key focus in the research. The study sheds light on the importance of stabilizing tin compounds effectively in water for fuel-producing reactions. Overall, the research contributes to the global effort in creating sustainable and efficient methods for hydrogen production.
