Abstract

Nanoscale Pd/Fe particles were fabricated on glassy carbon substrates by electrodeposition of Fe and the subsequently underwent galvanic replacement with Pd. Heterostructure was found by various characterizations of Pd/Fe particles. The process of electrochemical reduction of chlorobenzene on Pd/Fe particles were studied by cyclic voltammetry and constant-potential electrolysis. The removal rate of chlorobenzene on Pd/Fe particles reaches up to 90% within 120min using electrolysis at −0.1V in 0.1M H2SO4. Consequently, it shows that nanoscale Pd/Fe particles exhibited higher catalytic activity than bulk Pd for chlorobenzene reduction.
