摘要

A novel ternary sepiolite/Cu_2O/Cu(SCC) nanocomposite was successfully synthesized by a facile one-pot method. The Cu_2O/Cu nanoparticles in the SCC nanocomposite are well dispersed on the sepiolite surface. It exhibited enhanced photocatalytic performance in the degradation of congo red(CR), remarkably superior to that of Cu_2O or Cu_2O/Cu nanoparticles. Elemental copper in the SCC serves as a good electron acceptor to promote the transfer of photo-generated electrons in Cu_2O and suppress the recombination of the photo-generated electrons and holes of the composite. The enhanced photocatalytic efficiency is attributed to the synergistic effect of sepiolite and Cu_2O/Cu. This type of SCC nanocomposites is a promising candidate as photocatalytic material for environmental protection.
