Highly efficient photoelectrocatalytic degradation of 2,4-dichlorophenol using Mo-doped BiVO4 photoanode

Efficient removal of organic pollutants is of great significance for the sustainable development of aquatic ecosystems. Herein, an effective integrated ternary photoanode, NiFe-LDHs/Mo-doped BiVO 4 , was designed by a simple two-step electrodeposition method. The designed ternary photoanode showed a significant negative shift of onset potential compared to pristine BiVO 4 photoanode, and its photocurrent density was approximately 4.5 times higher than that of pure BiVO 4 . Moreover, the photoelectrocatalytic removal ability of 2,4-dichlorophenol (2,4-DCP) was investigated under simulated sunlight irradiation. The prepared composite achieved a degradation efficiency of 92.0% in 180 min and showed good reusability. This study provides a promising strategy for the treatment of organic pollutants wastewater with photocatalysts.
