摘要：

In this work, polyvinyl alcohol sponge filled with polystyrene nanoparticles was used as template to guide the polymerization of pyrrole monomer with PdCl2 as oxidant. After calcination, Pd@nitrogendoped carbon nanocapsules (NCCs) were synthesized on the networked carbon microfibers (NCFs). Pd@NCC/NCF has combined the advantages of one-dimensional carbon microfibers and zero-dimensional nanocapsules together, which not only provided numerous channels for mass diffusion, but also possessed high surface area. In catalytic reduction of 4-nitrophenol, it displayed better catalytic activity than corresponding counterparts prepared without filling polystyrene nanoparticles. (C) 2018 Elsevier B.V.
