Reductive removal of the organochlorine herbicide alachlor on Ni-coated graphite felt modified with Ag nanoparticles (Ag/Ni@GF) was studied. Ag/Ni@GF was prepared by spontaneous deposition of silver onto Ni-coated graphite felt (Ni@GF), which was previously obtained by electrodeposition of Ni onto graphite felt (GF). Interestingly, Ag/Ni@GF exhibited a high specific surface area of 26 m 2 g -1 determined by the Brunauer-Emmett-Teller
