Factors affecting photocatalytic performance through the evolution of the properties due to the phase transition from NaBiO3·2H2O to BiO2-x
文献摘要：
The phase transition process of a photocataly-tic system from NaBiO3·2H2O to BiO2-x has been investigated to understand the important factors that affect photocatalytic performance in a composite system.It is found that a proper amount of BiO2-x on the surface of NaBiO3·2H2O could effectively suppress the electron/hole recombination and increase the exposed reactive sites for photocatalytic reaction.A fully covered BiO2-x on NaBiO3·2H2O results in a dramatical decrease of photo-catalytic degradation of dye.An over long hydrothermal process can result in BiO2-x with reduced oxygen vacancies,which degrades the photocatalytic activity.Furthermore,the photocatalytic reduction ability of CO2 conversion has been investigated,indicating that the surface activity to different reactants also directly affects the catalytic performance.The investigation of the gradient phase transition process presents a clear guidance to construct a desired photocatalytic system,in addition to selecting gradient materials with suitable bandgap struc-ture and a morphology with different fraction and distribution of each component.The defect evolution of each component during construction of a composite is also an important factor that should be optimized and considered in making a composite to achieve high photocatalytic efficiency.
