Abstract

Herein, novel synchronous illumination X-ray photoelectron spectroscopy combined with an angle-resolved technique (AR-SI-XPS) was employed for the first time to identify the interatomic electron transfer and interface bond changes on Pt/TiO₂ photocatalysts, which could promote overall water splitting while restraining undesirable hydrogen back-oxidation.
