| Abstract | |
Semiconductor heterojunctions are interesting strategies for the development of efficient photocatalysts. In this paper we report the synthesis of ZnO:g-C3N4 heterostructures with different percentages of g-C3N4 (15%, 50% and 85%) using an easy and new method: precipitation of ZnO by alkaline solution at room temperature on g-C3N4 surface. The nucleation of ZnO nanoparticles had effective interaction on the g-C3N4 surface, showing good crystallinity and uniformity, which improved the heterostructure stability and the separation of photogenerated charge carriers, consequently increasing the photo-catalytic efficiency for both the degradation of the amiloride (AML) drug and the conversion of CO2 into products such as CO, CH4 and C2H4.
