采用原位生成溶剂热法成功制备了一种新型的异质结光催化剂，该异质结光催化剂在Co掺杂g-C3 N4上具有良好的分散性.在模拟太阳光照射下，以Cr 6+存在下的苯酚溶液为降解对象，考察了所制备的TiO 2/Co-g-C3 N4催化剂的光催化性能。与普通TiO 2/g-C3 N4催化剂相比，该催化剂对苯酚的光催化降解活性明显提高，但对Cr 6+的光催化还原活性明显降低。提出了这种光催化性能的机理。
A novel heterojunction photocatalyst with well-dispersed TiO2nanoparticles on Co-Doped g-C3N4has been successfully fabricated by an in situ generation solvothermal method. The photocatalytic performance of the as-prepared TiO2/Co-g-C3N4catalyst was evaluated by the degradation of phenol in the presence of Cr6 +under simulated sunlight irradiation. The catalyst exhibited markedly enhanced photocatalytic activity for degradation of phenol but obviously decreased photocatalytic activity for reduction of Cr6 +compared with common TiO2/g-C3N4catalyst. The mechanism for this photocatalytic performance was proposed.
