Abstract | Improving the platinum (Pt) mass activity for low-cost electrochemical hydrogen evolution is an important and arduous task. Here, a selective etching-reducing fluidized bed reactor technique is reported to create Ti vacancies and firmly anchor single Pt atoms on the active {100} facets of titanium carbide (TiC) to increase the Pt utilization efficiency and improve catalytic activity significantly by a synergistic effect between Ti vacancies and Pt atoms. The generated Ti vacancies are negatively charged and stabilize Pt atoms by forming covalent Pt-C bonds, showing excellent long-term durability. Pt single atoms (ultralow load of 1.2 mu g cm(-2)) on the defective TiC {100} show remarkable activity (24.9 mV at 10 mA cm(-2)) and a mass activity (49.69 A mg(-1)) approximate to 190 times that of the state-of-the-art Pt-C catalyst and nearly double the previously reported best values. The developed cation defect engineering exhibits excellent potential for fabricating next-generation advanced single-atom catalysts for large-scale hydrogen evolution at a low cost. |
