硫化镉-二氧化钛/分子筛复合光催化材料制备及性能研究

Abstract

Abstract:

The TiO₂ prepared by hydrothermal synthesis was loaded on the molecular sieve and compounded with CdS to prepare the CdS-TiO₂/zeolite composite.The phase composition,microstructure,morphology and spectral properties of the composites were characterized.The photocatalytic activity of the composite material was evaluated by photo-catalytic degradation of methylene blue as the probe reaction under visible light irradiation.The results showed that the TiO₂/zeolite composite catalysts had faster photo-catalytic activity than that of pure TiO₂ powders.Compared with the TiO₂/zeolite and CdS/zeolite, the CdS-TiO₂/zeolite composite catalysts had the best photo-catalytic activity.The optimal conditions of producing CdS-TiO₂/zeolitewere as follows: the mass concentration of CdS was 2.0 g/L,the water bath temperature was 80 ℃ and the reaction time was 4 h.

Key words: CdS-TiO₂-zeolite composite, catalyst, photo-catalytic activity
