Photocatalytic 2-iodoethanol (IEO) reductive coupling to 1,4-butanediol (BDO) over semiconductors is kinetically slow and shows low selectivity because of the negative reduction potential of IEO and competitive side reactions of the βHE radical intermediate. A molecular Ni catalyst rapidly extracts electrons from TiO₂ and thereby promotes photocatalytic reduction of IEO selectively.

TiO2 和催化镍络合物介导的光催化 2-碘乙醇偶联生产 1,4-丁二醇

由于 IEO 的负还原电位和β HE 自由基中间体的竞争性副反应，光催化 2-碘乙醇 (IEO) 与 1,4-丁二醇 (BDO) 的还原耦合在半导体上动力学缓慢且选择性较低。分子Ni催化剂快速从TiO ₂中提取电子，从而选择性地促进IEO的光催化还原。
