Colloidal synthesis of porous red phosphorus nanoparticles as a metal-free electrocatalyst for the hydrogen evolution reaction†
Abstract
Porous red phosphorus nanoparticles, P-RPNPs, were synthesized via a new colloidal approach and used as metal-free electrocatalysts in the hydrogen evolution reaction (HER). P-RPNPs were highly efficient in acidic media, required an overpotential of only 218 mV to reach 10 mA cm−2, and exhibited superior long-term durability.
