Abstract

The photocatalytic hydrogen production from aqueous methanol solution using titanium dioxide (TiO ) was investigated in the addition of metal particles including copper, lead, tin, and zinc. The results show that only the addition of copper particles enhances the hydrogen production. The copper usage and reaction temperature were further optimized for TiO /Cu photocatalyts. Under the optimal conditions, the hydrogen production using TiO /Cu as photocatalysts is approximately 68 times higher than that obtained with only TiO .
