A novel ZnCo₂O₄/Bi₂O₃ heterojunction photocatalyst was prepared, and the formation of the heterojunction was confirmed via HRTEM. Photocatalytic activity of as-prepared samples was evaluated through photodegradation of malachite green (MG). The degradation results show that the as-prepared 13% ZnCo₂O₄/Bi₂O₃ heterojunction photocatalyst exhibits higher activity than pure Bi₂O₃. 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 recombination rate of photogenerated electronhole pairs, which is driven by the photogenerated potential difference formed at the ZnCo₂O₄/Bi₂O₃ heterojunction interface.
