| 英文摘要 | Clarifying the reaction mechanism of electrocatalytic hydrodechlorination (EHDC) and identifying the catalytically favorable surface structure on Pd were crucial to maximize its power in remediating the chlorinated phenol pollutants. Herein, a study of the Pd facet-dependent EHDC performance toward 2,4-dichlorophenol (2,4-DCP) revealed the EHDC efficiency was governed by the H* yield on Pd at the potential above-0.80 V vs. Ag/AgCl, the phenol desorption at-0.80--0.90 V and the intensity of the electrostatic field-induced repulsive force between 2,4-DCP and the cathode at the potential beyond-0.95 V. Further rationalization of the facet effect with the surface electronic/geometric structure of Pd demonstrated the density of active sites for H* generation and the d band center were two key struc-tural properties. The Pd (110) with large density of active sites and the Pd (111) with a low d band center were the ideal facet to facilitate H* generation and phenol desorption, respectively. (c) 2020 Elsevier Inc.
