Method for photocatalytic coupling of ether compounds

The invention relates to a method for photocatalytic coupling of ether compounds. According to the method, an ether compound is adopted as a substrate, a bimolecular C-C coupled product is prepared under the action of a titanium dioxide semiconductor photocatalyst loaded with noble metal and under the irradiation of an ultraviolet lamp, meanwhile, along with the generation of hydrogen, the reacted catalyst is easy to separate and recover, the selectivity of the bimolecular C-C coupled product is greater than 90%, and the yield is greater than 70%. The catalyst prepared by the method is high in catalytic activity, long in service life and easy to prepare, the production cost can be greatly reduced, and potential application prospects are achieved. 本发明涉及一种光催化偶联醚类化合物的方法。该方法采用醚类化合物作为底物，在负载贵金属的二氧化钛半导体光催化剂的作用下，在紫外灯照射下制备双分子C-C偶联的产物，同时伴随着氢气的产生，反应后的催化剂易于分离回收，双分子C-C偶联产物的选择性大于90％，产率大于70％。该方法催化剂催化活性高，寿命长，易于制备，可大幅降低生产成本，有潜在的应用前景。
