Abstract

With carbon cloth (CC) as a substrate, the composite of CC/TiO₂/Ag@AgCl was successfully prepared via a successive chemically coupled method, in-situ deposition method and the followed photogenic reduction method. The adsorption-photocatalytic degradation activities and the photoelectric properties of CC/TiO 2/Ag@AgCl were further studied. The results indicated that 96. 9% of RhB could be captured and degraded in the presence of CC/TiO₂/Ag@AgCl composites under 120 min UV-vis irradiation, which was higher than those of pure TiO₂(83. 8%) and Ag@AgCl (78. 6%). It was verified that CC/TiO₂/Ag@AgCl catalyst broadened the light absorption range and showed more efficient photocarrier separation and transfer efficiency, which was beneficial to inhibit the electron-hole pair recombination and the improvement of photocatalytic activity. The capture of active pieces experiments indicated that the free ·OH radicals and ·O₂^- radicals were the main active oxidizing species involved in the RhB photoreaction process of CC/TiO₂/Ag@AgCl.
