Abstract:
Herein, 2D siloxene terminated by surface functional groups of Si-H and Si-OH is demonstrated to be an effective support for the spontaneous deposition of iridium nanoparticles (Ir NPs) to promote HER electrocatalysis. With ultra-low Ir loading, the obtained Ir NPs/siloxene electrocatalyst shows superior electrocatalytic activity toward the HER.
