Tuning Oxygen Vacancy Density in TiO2 Hosts for Stabilizing Nanoscale Pt Species and Enhancing Hydrogen Evolution
Developing efficient electrocatalysts for the hydrogen evolution reaction (HER) with improved noble‐metal utilization is essential for sustainable hydrogen production. Here, defect‐engineered TiO2−x supports were developed to stabilize dispersed Pt nanoparticles (∼5 nm) and regulate metal–support interactions. Oxygen v...
