Black Talc-Based TiO2/ZnO Composite for Enhanced UV-Vis Photocatalysis Performance

Herein, using black talc as a carrier, a ternary black talc-TiO2/ZnO composite photocatalyst was prepared by the sol-gel method, and the effect of the black talc on the hetero-structure properties of the TiO2 and ZnO was systematically studied. The prepa...
