英文摘要: The construction of an efficient and robust catalyst for the electrochemical reduction of carbon dioxide into energy-rich products has recently received considerable attention. Herein, a Cu/TiO2 nanoparticles modified nitrogen-doped graphene (Cu/TiO2/NG) carbon material is fabricated for the selective reduction of CO2 into different alcohols. We found the Cu/TiO2/NG nanocomposite across a range of potentials for the electroreduction of CO2 exhibits dual catalytic ability, possessing an outstanding ability to produce methanol (reaching a maximum faradaic efficiency of 19.5% at a potential of −0.20 V vs. the reversible hydrogen electrode (RHE)) and a capability to produce ethanol (with a high faradaic efficiency up to 43.6% at −0.75 V vs. RHE). In addition, the Cu/TiO2/NG composite shows remarkable stability and reusability at both reductive potentials in the electrochemical process. The designed Cu/TiO2/NG composite may offer a new simple method based on earth-abundant metals to construct robust electrocatalysts for CO2 reduction. © 2018 Elsevier Ltd Citation statistics:
