Abstract

Supported nano Cu/Fe bimetal was prepared by using KBH₄ as the reducing agent when micro-scale graphite as a support material. This supported nano bimetal showed the well reductive chlorination to trichloroethylene(TCE) in the solution. The nano Cu/Fe with spherical particle and spherical nanocluster structure were synthesized in the H₂O and ethanol/H₂O system respectively. The size of spherical nano Cu/Fe was non-uniformly when the Fe²⁺ concentration was 0.02mol/L during the synthesizing. And the Cu/Fe with spherical nanocluster had the uniformly sphere shape while the Fe²⁺ concentration was 0.05mol/L. When the Fe²⁺ concentration was 0.2mol/L, bimetal had the nano whisker shape. The experiment results showed that the nano Cu/Fe bimetals which were synthesized in the ethanol/H₂O system and the Fe²⁺ concentration was 0.05mol/L had the fastest dechlorination rate on TCE.
