| Abstract |
Reduction of CO2 has been receiving increasingly considerable interest in terms of environmental and long term energy-security. An essential requirement for CO2 reduction is to energy-driven flow of electrons with multiple-electron chemical processes that can make C–H and C–C bonds and can cleave C–O bonds. Such processes require a highly efficient catalyst, among which novel metal nanostructures have been regarded as a potential candidate. Here, Au, Ag, and Cu nanoparticles embedded on nitrogen-doped graphitized nanodiamonds (ND) were synthesized as efficient electrocatalysts for the CO2 reduction reaction. The NDs were transformed into the graphitized onion-like form by laser-induced reaction in ethanol, were doped with the N atoms by the thermal annealing under NH3 gas. The metal nanoparticles were directly grown on the graphitized N-doped NDs. We proposed that the efficient performance of these hybrid nanostructures is credited to a synergic effect of the active metal nanoparticles and the pyrrolic-like N electronic structures of NDs. This finding may lead to a new strategy developing cost-effective electrocatalysts for reducing CO2 and converting it into useful chemicals. |
