摘要
We prepared CdS@CS/PVA inverse opal (IO) films by the colloidal photonic crystal (CPC) template method. The photonic structure of the CdS@CS/PVA IO films consists of three-dimensional periodic macropores interconnected by CS/PVA polymers. The as-prepared CdS@CS/PVA IO films were utilized as photocatalysts for the degradation of methylene blue dyes. The degradation rate of methylene blue by the CdS@CS/PVA IO film catalyst was 92%, while that of the CdS@CS/PVA film catalyst was 55% for 6 h. The photocatalytic degradation effect of the CdS@CS/PVA IO film catalyst on methylene blue is [Formula: see text]1.7 times higher than that of the CdS@CS/PVA film catalyst, which proves that the introduction of the inverse opal structure into the photocatalyst is beneficial to improve the efficiency of the photocatalyst for degrading dyes.
