Abstract
- Objective: A highly active and stable composite photocatalyst which can be used in practical environmental remediation was developed. Methods: g‐C3N4/SnO2/BiPO4 ternary composites (CN/SO/BPO) were synthesised via simple impregnation, and their texture structure, morphology, and surface composition were deeply characterized. Results: In just 25 min under visible‐light radiation, CN/SO/BPO almost eliminated rhodamine B, and the observed rate constant for the reaction was almost 36 and 3 times higher in comparison to that of CN/BPO and SO/BPO, respectively. Conclusions: On the basis of experimental outcomes and DFT calculation, the direct Z‐type structure of CN/SO/BPO lead to the improved photogenerated charge separation efficiency, as confirmed by surface photovoltage spectroscopy, electrochemical impedance spectroscopy, and transient photocurrent responses.
