Insights into the relationship between the color and photocatalytic property of attapulgite/CdS nanocomposites

Attapulgite/CdS (APT/CdS) nanocomposites were fabricated by hydrothermal decomposition of the cadmium-thiourea complex in the presence of APT. The incorporating of APT not only adjusted the color of APT/CdS nanocomposites and controlled the growth of CdS nanoparticles on the surface of APT without the free agglomeration, but also changed the band-gap energy of nanocomposites to affect their photocatalytic property for degradation of organic dyes. Interestingly, there was a close relationship between the color and the photocatalytic property of APT/CdS nanocomposites. The as-prepared nanocomposites with the optimal color properties exhibited the optimal photocatalytic performance for degradation of methylene blue, methyl violet and congo red within 70?min. The key bridge between the color and the photocatalytic activity was mainly band-gap energy. Therefore, it was presumed that the photocatalytic activity of APT/CdS nanocomposites could be evaluated directly from their color property.
