In a recent international collaborative study led by Flinders University, experts have made significant progress in the development of sustainable and efficient hydrogen production from water using solar power. The study, conducted in collaboration with experts from South Australia, the US, and Germany, identified a novel solar cell process that could be crucial for future technologies in green hydrogen production. By combining this process with a catalyst developed by US researchers, a new class of stable 'core and shell Sn(II)-perovskite' oxide solar material was found to be a potential catalyst for the oxygen evolution reaction in producing pollution-free hydrogen energy. The research, published in The Journal of Physical Chemistry C, paves the way for advancements in carbon-free hydrogen technologies using environmentally friendly power sources. The study emphasizes the importance of tin compounds in water stabilization and their effectiveness. Solar photovoltaic research worldwide is aiming to develop cost-effective perovskite generation systems as an alternative to traditional silicon panels. The study also highlights the potential of solar-driven processes for industrial-scale hydrogen production. Overall, the research signifies a positive step forward in the quest for sustainable and efficient green hydrogen production.
