An international team of researchers (UK, Japan) has developed a technology that integrates lanthanum- and rhodium-doped SrTiO3 (SrTiO3:La,Rh) and molybdenum-doped BiVO4 (BiVO4:Mo) light absorbers modified by phosphonated Co(II) bis(terpyridine) and RuO2 catalysts onto a gold layer. The monolithic device provides a solar-to-formate conversion efficiency of 0.08 ± 0.01% with a selectivity for formate of 97 ± 3%. It produced almost no by-products. The new technology is more robust and produces clean fuel that is easier to store and shows potential for producing fuel products at scale…read more. TECHNICAL ARTICLE
