MOFs-Derived Fusiform In2O3 Mesoporous Nanorods Anchored with Ultrafine CdZnS Nanoparticles for Boosting Visible-Light Photocatalytic Hydrogen Evolution

The development of efficient visible-light-driven photocatalysts is one of the critically important issues for solar hydrogen production. Herein, high-efficiency visible-light-driven In 2 O 3 /CdZnS hybrid photocatalysts are explored by a facile oil-bath method, in which ultrafine CdZnS nanoparticles are anchored on NH 2 -MIL-68-derived fusiform In 2 O 3 mesoporous nanorods. It is disclosed that the as-prepared In 2 O 3 /CdZnS hybrid photocatalysts exhibit enhanced visible-light harvesting, improves charges transfer and separation as well as abundant active sites. Correspondingly, their visible-light-driven H 2 production rate is significantly enhanced for more than 185 times to that of pristine In 2 O 3 nanorods, and superior to most of In 2 O 3 -based photocatalysts ever reported, representing their promising applications in advanced photocatalysts.
