A method for preparing N-doped BiVO 4 ‑OVs/GO nanocomposite structure photocatalytic material and application thereof. The preparation method comprises: dissolving a certain molar amount of Bi(NO 3 ) 3 .5 H 2 O in glycerol; A certain molar amount of NaVO 3 ·2 H 2 O was dissolved in deionized water; the aforementioned solutions were mixed; a certain amount of NaN 3 was added, and a certain mass fraction of graphene oxide (GO) was added, and the mixture was transferred to the PTFE lining The solvothermal synthesis product was centrifuged at 10,000 rpm, washed with deionized water and ethanol, and dried at 60 °C for 4 h to obtain N-doped BiVO 4 ‑OVs/GO nanocomposite structure photocatalysis. Material. The invention has the advantages of narrow band gap, wide light response range, high electron-hole separation rate and strong catalytic ability, and significantly improves the utilization efficiency of solar energy. |
