摘要: Pd-based bimetallic materials have been widely studied for the effective hydrodechlorination (HDC) of aqueous chloroorganic compounds. However, reaction functions metal substrates and mechanism responsible changes in reactivity not fully elucidated. Here, we synthesized bimetals with Mg, Al, Mn, Zn, Fe, Sn, Cu to explore influence on HDC 2-chlorobiphenyl (2-PCB). Bimetals exhibited disparate toward 2-PCB acidic solution. Among these bimetals, Pd/Al particles presented highest stability relatively high remove 2-PCB. The maintenance regeneration Al substrate are attributed its particular corrosion properties which provide an efficient recycling between element oxide layer. fresh reacted samples were characterized by ICP-OES, SEM, XRD, BET. investigation pH effect further revealed behaviour surface. Pd loading amount indicated that optimal content terms catalytic activity was related dispersion degree. Finally, a surface proposed.
