Preparation of MoP/C nanocomposites and its photocatalytic performance for the degradation of organic dye

MoP as an important transition metal phosphide material, has been widely used in catalysis field due to its excellent catalytic performance and chemical stability. Combining MoP with carbon material can effectively enhance its dispersibility and stability, as well as the carrier transport rate, thereby further improving its photocatalytic performance. In this study, MoP/C nan-osheets were prepared by the sodium chloride template method, and its photocatalytic ability to degrade methylene blue was studied by adjusting the amount of MoP/C added. The results showed that MoP was uniformly distributed on the surface of the carbon nano-sheets to form the composites. The highest removal efficiency of MB (20 mg/L, 200 mL) was observed when 5 mg of MoP/C was added and reacted for 4 h under 6 °C light, reaching 70.7%, At the same time, this study systematically investigated the active substances produced during the photocatalytic degradation of methylene blue, and found that ·OH and ·O 2 − play a key role in the photocatalytic process. Furthermore, MoP/C also used to photocatalytic degradation of tetracycline hydrochloride and diplayed good photocatalytic performance. This study provides new ideas for the application of transition metal phosphides as photocatalyst in the environmental and energy fields.
