Abstract:
Photocatalysis is a promising technology to solve the environment problems. Charge separation efficiency and oxidation capability are both vital factor determining the performance of photocatalysts. In this work, 2D g‐C 3 N 4 is applied to modify Bi 2 MoO 6 via an in situ hydrothermal method to design visible‐light‐driven Z‐scheme catalyst. The principle of this structure is to use the opposite surface charge of each component, maintaining the strong redox ability of photogenerated electrons and holes, preventing the recombination of photogenerated carrier effectively. As expected, the photodegradation performance of as‐prepared composites enhances dramatically compared with the pure Bi 2 MoO 6 . Afterward, kinetics and probable reaction mechanism are investigated and analyzed. It is proved that photogenerated carrier can be separated rapidly by tightly all‐solid‐state Z‐scheme junction. This work can provide a sight for finding controllable synthesis route of obtaining newly efficient visible‐light‐driven Z‐scheme photocatalysts.
