摘要: 以活化的碳布（CC）为基底材料，依次通过化学偶联法、原位沉积法和光致还原法制备CC/TiO₂/Ag@AgCl复合材料，并对其吸附-光催化降解性能、光电性能等进行研究.结果表明：CC/TiO₂/Ag@AgCl复合材料在紫外-可见光照射120 min条件下对罗丹明B（RhB）的降解率可达96.9%，高于TiO₂（83.8%）和Ag@AgCl（78.6%），优异的光催化降解性能归因于CC/TiO₂/Ag@AgCl复合材料可以更有效地拓宽光吸收范围，促进光生电子-空穴对的分离和电子转移效率，抑制光生载流子的复合；羟基自由基（·OH）和超氧阴离子自由基（·O₂^-）是复合材料光催化降解RhB过程中的主要活性物质.

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.
