Photocatalytic Hydrogen-Generation of Polyoxotungstate Nano-Clusters from Biomass

Article Preview

Abstract:

The photocatalytic reaction of polyoxotungstate, [BW12O40]5- and [SiW12O40]4-, led to the generation of hydrogen gas from biomass such as a sugarcane juice and tapioca starch under irradiation of UV light. These photoreactions were investigated in the pH dependence. The results showed that hydrogen was obtained at 2
