Boron doping activate strong metal-support interaction for electrocatalytic hydrogen evolution reaction in full pH range

Developing rhodium-based electrocatalysts with strong metal-support interaction (SMSI) is crucial for hydrogen evolution reaction (HER) in full pH range, but it is still challenging. In this work, a boron doping strategy is proposed to activate the SMSI of ultra-small Rh nanoparticles encapsulated by N-doped carbon matrix ([email protected]). Density functional theory (DFT) reveals that boron doping can regulate the electronic structure and the water adsorption energy, further boosting the HER activity. Consequently, the as-prepared [email protected] nanospheres possess Pt-like activity for HER with low overpotentials in 1.0?M KOH (?10 = 26?mV), 0.5?M?H2SO4 (?10 = 43?mV), and 1.0?M PBS (?10 = 70?mV), as well as outstanding stability. This work opens up a new way to construct remarkable pH-universal electrocatalysts.
