摘要：Commercial nickel nanoparticles (Ni NPs) were directly converted to efficient electrocatalysts for CO(2)reduction by urea-Ni solid powder pyrolysis, in which a Ni, N-co-doped graphite carbon shell wraps the Ni NPsin situ. 98.3% CO selectivity was realized with a current density of -20.2 mA cm(-2)and an overpotential of 0.69 V.
