Core/shell structured CdS/polydopamine/TiO (CdS/PDA/TiO) ternary hybrids were fabricated by sequentially coating of PDA and TiO on CdS nanospheres through dopamine self-polymerization and TBOT hydrolysis and hydrothermal processes. The reaction rate constants of CdS/PDA/TiO ternary hybrids toward the degradation of RhB, MB and phenol were more than 3 times higher than those of CdS/TiO hybrids. The remarkably improved photocatalytic activity was attributed to enhanced light absorption and charge carrier separation efficiency associated with the introduction of PDA.
核壳结构的 CdS/聚多巴胺/二氧化钛（CdS/PDA/TiO）三元杂化物是通过多巴胺自聚合和 TBOT 水解及水热过程，将 PDA 和 TiO 依次包覆在 CdS 纳米球上制备的。CdS/PDA/TiO 三元杂化物对 RhB、MB 和苯酚的降解反应速率常数比 CdS/TiO 杂化物高 3 倍以上。显著提高的光催化活性归因于引入 PDA 后增强的光吸收和载流子分离效率。
