Catalytic Dechlorination of Monochloroacetic Acid by Film–Supported Pd/Fe Bimetallic Nanoparticles

Abstract:

Three novel kinds of support film, including PVDF-PAA film, PVDF·TiO2–PAA film and PVDF–g–AA film, were synthesized and used to immobilize the Pd/Fe bimetallic nanoparticles (NPs). The immobilized Pd/Fe bimetallic NPs systems were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, contact angle analysis, and X-ray photoelectron spectroscopy. The dechlorination efficiency of the immobilized bimetallic NPs systems were tested and discussed by dechlorinating monochloroacetic acid (MCAA). Comparing with free suspended Pd/Fe NPs, bimetallic NPs with support films appeared better catalytic dechlorination efficiency, and the dechlorination efficiencies of 10 mg/L MCAA in 120 min by Pd/Fe NPs immobilized in PVDF–PAA film, PVDF·TiO2–PAA film and PVDF–g–AA film were 56.33%, 71.01% and 75.51%, respectively.
