Abstract |
Reduction of CO2 has been receiving increasingly considerable interest in terms of environmental and long-term energy security. Here, we report that ZnO nanowire array deposited with metal-nanoparticles (Au, Ag, Pt) was synthesized as efficient electrocatalysts and photoelectrocatalysts for CO2 reduction reaction. Vertically aligned ZnO nanowires were synthesized by the chemical vapor deposition (CVD) on indium tin oxide (ITO) substrates. A successive ion layer adsorption (SILAR) method was developed to deposit the metal nanoparticles. We proposed that these nanowire array are credited to a synergic effect of excellent efficiency and high selectivity of CO2 reduction to CO. This finding may lead to a new strategy for developing cost-effective electrocatalysts and photoelectrocatalysts for reducing CO2.
