Monolithic nickel foam supported macro-catalyst: Manipulation of charge transfer for enhancement of photo-activity

The dimensions and structure of conventional photocatalysts severely limit their industrial applications. In view of this, a novel monolithic supported macroscopic catalysts (SMCs) was successfully designed and developed for the first time. The visible-light responsive and reusable Zn 0.95 Fe 0.05 S@TiO 2 /nickel foam (ZFS@TiO 2 /NF) SMCs was assembled with ZFS particle catalyst as a light responder that was protected by defective TiO 2 as a carriers capture layer, the multihole and flexile nickel foam material was induced into photocatalytic system with the function of supporting and charge storage. This integrated material exhibited an unprecedentedly high utilization of carriers by a new set of unique “generation-capture-migration-utilization” path, which was attributed to the key properties of the integration of three independent materials. Furthermore, the loading operation can maximum exert dimensions and interfaces optimization of ZFS and TiO 2 . This work proposes a novel mechanism of charge transfer for rational design of macro photocatalysts.
