Synthesis and characterizations of CoPt nanoparticles supported on poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) functionalized multi-walled carbon nanotubes with superior activity for NaBH_4 hydrolysis

摘要

We present here a facile strategy for synthesis of CoPt nanoparticles supported on poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) functionalized multi-walled carbon nanotubes (MWCNTs).The as-prepared CoPt-PEDOT:PSS/MWCNT catalyst was characterized with UV-vis spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron. The well-supported and low-Pt-content nanostructure catalyst exhibits superior catalytic activity for the NaBH_4 hydrolysis reaction with a 47.3 kJ mol~(-1) of activation energy. The maximum hydrogen generation rate is 6900 mL min~(-1) g~(-1) at 298 K.
