Abstract

Attapulgite clay-supported CdS composites were synthesized via hydrothermal approach and applied to remove Rhodamine B (RhB). The structural, morphological, and physicochemical properties of the materials were systematically characterized by XRD, TEM, XPS, BET and UV-Vis DRS. The combination of CdS and attapulgite could enhance active site availability and surface area, thereby boosting photocatalytic activity.The optimized CdS/attapulgite composite demonstrated remarkable photocatalytic efficiency under visible-light illumination. In addition, a potential photocatalytic degradation mechanism by the composites was proposed.
