摘要

报道了一种制备银多孔碳纳米纤维的简单方法。采用静电纺丝和高温煅烧法制备了银多孔碳纳米纤维。该工艺以AgNO3-PMMA/PAN溶液为静电纺丝的前驱体溶液,通过高温煅烧制备银纳米颗粒和孔。通过苯乙烯环氧化反应证实了银多孔碳纳米纤维的催化活性。在催化过程中,苯乙烯的转化率为71%,苯乙烯氧化物的选择性为83%。

Synthesis of Ag Porous Carbon Nanofiber by Electrospinning and Their Use as Catalyst for Styrene Epoxidation
A simple method to prepare the Ag porous carbon nanofiber is reported. Ag porous carbon nanofiber was prepared by electrospinning and high temperature calcination. In this process, AgNO3-PMMA/PAN solution was the precursor solution of electrospinning, and Ag nanoparticles and pores were made by high temperature calcination. The catalytic activity of the Ag porous carbon nanofibers was confirmed by the styrene epoxidation. In the catalytic process, the conversation of styrene was 71% and the selectivity of styrene oxide was 83%.
