A facile approach to synthesize CdS-attapulgite as a photocatalyst for reduction reactions in water.

ABSTRACT: At room temperature, a facile approach has been utilized for preparing novel CdS-attapulgite (CdS-ATP) composites and the composites were applied in photocatalytic reduction of p-nitrophenol and Cr(vi). The effect of ATP on the photocatalytic activity of the CdS-ATP composites were studied by controlling the mass ratio of attapulgite. The results showed that the CdS-20%ATP composite has an excellent photocatalytic activity. In order to figure out the key to improve the photocatalytic efficiency, the prepared composites were characterized by Brunauer-Emmett-Teller (BET) specific surface area, UV-vis diffuse reflectance spectroscopy (DRS) and electrochemical impedance spectroscopy (EIS). The superior photocatalytic performance of the CdS-20%ATP composite can be ascribed to the existen
