▎ 摘  要

NOVELTY - Bismuth vanadate quantum dot/reduced graphene oxide (RGO)/graphite phase carbon nitride ternary composite photocatalyst is composed of bismuth vanadium oxide (BiVO4) quantum dots, reduced graphene oxide and graphite phase carbon nitride (g-C3N4). USE - Bismuth vanadate quantum dot/RGO/graphite phase carbon nitride ternary composite photocatalyst. ADVANTAGE - The photocatalyst can realize the effective separation of photogenerated carriers, improving the photocatalytic performance, and realizing the high-efficiency degradation of organic matter, bacteria and other pollutants. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the bismuth vanadate quantum dot/RGO/graphite phase carbon nitride ternary composite photocatalyst, which involves: (A) using bismuth nitrate pentahydrate (Bi(NO3)3.5H2O) as the bismuth source, ammonium vanadium oxide (NH4VO3) as the vanadium source, sodium oleate as the surfactant, and graphene oxide as the matrix; (B) synthesizing BiVO4 quantum dot/RGO composite material of BiVO4 quantum dot modified two-dimensional flake RGO by hydrothermal method; (C) using melamine as the precursor to heat-treat to prepare block g-C3N4, and then peeling off to obtain layered nano g-C3N4; (D) using ethanol as the solvent, and self-assembling and compounding the BiVO4 quantum dot/RGO composite material and the layered nano g-C3N4 by immersion and stirring, and (E) obtaining target product BiVO4 quantum dot/RGO/g-C3N4 ternary composite photocatalyst is obtained.
