摘要

In order to dynamically degrade toluene, g-C3N4/Bi2WO6/ACF composites were compounded by immersing g-C3N4/Bi2WO6 prepared via one-step hydrothermal method in the ACF which with various load in this paper. The effects of Bi2WO6 /ACF loading capacity, toluene concentration, light intensity and wavelength on the degradation rate of toluene were investigated respectively. The results show that 40 g-C3N4/Bi2WO6 photocatalyst prepared by water thermal method is evenly covered on ACF, forming a thin film and no agglomeration is produced. Under the condition of toluene concentration of 500 mg/m(3 )and the light intensity of 24 w, the removal effect of gas phase toluene is the highest when the mole ratio of g-C3N4/Bi2WO6 is 40, which is 1.83 times higher than Bi2WO6. The possible photocatalytic degradation pathways and mechanisms of toluene are proposed. Hence, the g-C3N4/Bi2WO6/ACF composite material has an excellent removal effect and application potential in removing organic pollutants (toluene) in the atmosphere.
