Abstract

In this study, a highly air stable and eco-friendly methyl ammonium bismuth iodide (MA₃ Bi₂ I₉ ) perovskite-like material has been prepared. After physiochemical characterizations, the synthesized MA₃ Bi₂ I₉ was utilized as photo-catalyst towards hydrogen production. It is important to design and synthesize lead (Pb)-free perovskite-like material (MA₃ Bi₂ I₉ ) for photo-catalytic hydrogen-production applications. The synthesized MA₃ Bi₂ I₉ exhibits excellent photo-catalytic hydrogen generation with a production rate of 11.43 μmolg^-1 h^-1 . In the presence of a platinum co-catalyst, the hydrogen production rate further increases to 172.44 μmolg^-1 h^-1 . The MA₃ Bi₂ I₉ photo-catalyst also demonstrates excellent cyclic stability.
