Ag/Au nanocluster loaded BiO photocatalyst for methyl orange dye photodegradation.

Visible-light-sensitive Ag and Au nanocluster loaded BiO (Ag-BiO and Au-BiO) semiconductor photocatalysts have been synthesized. The composite materials exhibited increased photocatalytic degradation of the azo-dye pollutant, Methyl Orange (MO). In addition, Au-BiO (Au-7% wt) showed the highest MO degradation rate (0.
