Synthesis of platinum decorated bismuth vanadate (Pt-BiVO₄) nanocomposite for photocatalytic hydrogen production

In the past years, bismuth vanadate (BiVO4) has emerged as rising star and gained much attention for various photocatalytic and electrochemical applications. In this study, our group report the precipitation synthesis of BiVO4 and its photocatalytic properties for the generation of hydrogen (H-2). The obtained results demonstrate the H-2 generation of 32.4 mu mol g(-1). Further studies were carried out by employing platinum (Pt) as co-catalyst which dramatically improved the H(2 )generation. The obtained results show that an enhanced 115.7 mu mol g(-1) H-2 was generated using BiVO4 as photocatalyst in presence of Pt co-catalyst. Further studies also exhibit the presence of good stability of the BiVO4 as photocatalyst and suggested its potential for reusability studies.
