英文摘要： In electrocatalysis,enhancement of the mass transfer and loading capacity of the carriers as well as control over the size and distribution of noble metal nanoparticles on the carriers is of great significance to enhance the electrocatalytic properties of the materials. Starting from the electrocatalytic properties of noble metal nanoparticles and using conducting polymers as both the reducing agents and carriers, in situ growth of metal nanoparticles on conducitng polymer 1D nanomaterials and membranes and preparation of conducting polymer-noble metal nanocomposites through one-step interfacial polymerization will be conducted in this project. In situ modulation of the size, density and distribution of Au, Pt and Pd nanoparticles on conducting polymer carriers will be realized. The as-prepared conducting polymer-noble metal nanocomposites will be applied in electrocatalysis studies. Through comparative analysis of the electrocatalytic properties in different systems, the internal relations between the size, density, distribution of metal nanoparticles, charge transfer between conducting polymer and metal, and electrocatalytic properties will be interpreted.Through this project, we strive to a deeper understanding of the chemical reduction properties of conducting polymers, and a new way to prepare stable noble
