A Ternary Photocatalyst with Double Heterojunctionsfor Efficient Diesel Oil Degradation

摘要

The photodegradation is a potential technology to solve environmental issues such as the diesel oil pollution. The titanium dioxide/graphitic carbon nitride (TiO2/g-C3N4) photo- catalyst is widely used for the photodegradation of pollutants. However, the performances of this binary photocatalyst such as the degradation efficiency and cyclic stability are still unsat- isfactory for real applications. In our work, we introduce a p- type NiO semiconductor into the binary TiO2/g-C3N4 (98: 2) photocatalyst by a simple dipping method.
