A novel Znco.2O_4/Bi_2O_3 heterojunction photocatalyst was prepared, and the formation of the heterojunction was co.firmed via HRTEM. Photocatalytic activity of as-prepared samples was evaluated through photodegradation of malachite green(MG). The degradation results show that the as-prepared13% Znco.2O_4/Bi_2O_3 heterojunction photocatalyst exhibits higher activity than pure Bi_2O_3. The MG degradation rate for the as-prepared catalyst is as high as 94%. The enhanced photocatalytic activity is mainly attributed to the broad photoabsorption and low reco.bination rate of photogenerated electronhole pairs, which is driven by the photogene rated potential difference formed at the Znco.2O_4/Bi_2O_3 heterojunction interface.
