Reversed Charge Transfer and Enhanced Hydrogen Spillover in Platinum Nanoclusters Anchored on Titanium Oxide with Rich Oxygen Vacancies Boost Hydrogen Evolution Reaction

Zhen-Wei Wei et al.

Summary: The study demonstrates that Pt nanoclusters supported on porous TiO2 nanosheets with rich oxygen vacancies exhibit significantly higher catalytic activity for the HER compared to those supported on TiO2 with deficient oxygen vacancies. This is attributed to the ability of the TiO2 support with rich oxygen vacancies to facilitate reversed charge transfer and enhanced hydrogen spillover, promoting proton reduction and hydrogen desorption at Pt catalytic sites. This work provides a new strategy for the rational design of highly efficient HER catalysts.
