Vacancy engineering of TiO2 with low Pt content for efficient hydrogen generation

Chem. Commun., 2025, Advance Article DOI: 10.1039/D5CC02554K, Communication Jianyang Gao, Yuanzong Shen, Jinxiao Gao, Liantao Xin, Weiping Xiao, Guangrui Xu, Dehong Chen, Lei Wang, Fusheng Liu, Zexing Wu An ultrafast (70 s) microwave quasi-solid approach is applied to design black TiO2-supported low content Pt (Pt/TiO2). The metal–support interactions of Pt and TiO2 endow the prepared catalyst with exceptional HER performance in acidic electrolytes.
