Universal synthesis of single-atom electrocatalysts <i>via in situ</i> fluoride ion etching for hydrogen evolution.

ABSTRACT: Single-atom catalysts (SACs) have attracted considerable interest in the field of electrocatalysis due to their high efficiency of metal utilization and catalytic activity. However, traditional methods of SACs fabrication are often complex and time-consuming. Herein, F-Ru@TiO _x N _y was synthesized using a straightforward and universal approach via in situ surface etching and heteroatoms immobilization on a vacancies-rich hierarchical TiO _x N _y nanorods array. The fluorine ion-etched TiO _x N _y nanorods could produce abundant oxygen vacancies and F-Ti/F-C bonds, which could capture and stabilize Ru heteroatoms by strong host-guest electronic interactions. Due to the synergistic
