A new catalytic route for the lactonization of diols was developed by using a metal-loaded TiO₂ photocatalyst. In particular, Pt-loaded rutile TiO₂ exhibited a high photocatalytic activity with high selectivity. In addition, it was found that a heterogeneous acid catalyst can accelerate this photocatalytic lactonization.

负载铂的二氧化钛光催化剂对二醇进行脱氢内酯化†

通过使用负载金属的TiO ₂光催化剂，开发了一种新的二醇内酯化的催化途径。特别地，负载Pt的金红石TiO ₂表现出高的光催化活性和高的选择性。另外，发现异质酸催化剂可以加速该光催化内酯化。
