Abstract

The photodegradation of Methyl orange (MO) and Congo red (CR) dyes was studied with pure Cu2O and composite gold doped Cu2O (Au/Cu2O) photocatalysts. A novel facile chemical reduction method at a very low temperature was used to prepare the photocatalysts. The Au/Cu2O composite shows excellent photocatalytic activities on both MO and CR, especially CR. Within 90 mins, the degradation efficiency of 99% and 79% was obtained by Au/Cu2O for CR and MO respectively. The doping effectively enhanced the separation of generated charged carriers to increased MO and CR dye degradation.
