英文摘要: Pd/C catalysts facilitate CO2 electroreduction to formate with high Faradaic efficiency at low overpotentials. However, they are prone to deactivation due to CO poisoning. In this work, three carbon-supported Pd-Pt catalysts with different metal deposition sequences are prepared and their efficacy towards formate production over the Pd surface is studied. X-ray photoelectron spectroscopy and X-ray absorption spectroscopy results show that the surface composition and coordination number of Pd-Pd in carbon-supported Pd-Pt catalysts are greatly influenced by the order in which Pd and Pt nanoparticles (NPs) are deposited. The deposition of Pt NPs prior to Pd NPs on the carbon support gives the best results for formate production with high Faradaic efficiency. (C) 2017 Elsevier B.V. All rights reserved.
