An international research team led by Flinders University in Australia has made significant progress in nanoscale chemistry to improve the sustainable generation of hydrogen using solar power. The study discovered a new kinetically stable solar material, 'core and shell Sn(II)-perovskite' oxide, which could serve as a catalyst for the oxygen evolution reaction in producing clean hydrogen energy. Collaborating with Baylor University and Universität Münster, the research aims to drive carbon-free green hydrogen technologies with efficient electrolysis. The study emphasizes the importance of stabilizing tin compounds for effective water splitting and hydrogen production. Published in the ACS Journal of Physical Chemistry C, the research showcases the potential of solar-driven processes in industrial-scale hydrogen generation, offering a greener alternative to traditional methods. The findings open new possibilities for the advancement of high-performance, affordable hydrogen production systems that are environmentally friendly and sustainable.
