以硼氢化钠为还原剂，聚乙烯吡咯烷酮为分散剂，通过简单的吸附-还原法制备了胍基化聚（2，6-二甲基-1，4-苯醚）（GPPO）中空纤维膜（HFM）负载Au纳米粒子。该多相催化剂在室温下对多种芳香硝基化合物的还原反应表现出很高的催化活性，并可重复使用多次，如硝基苯的还原反应，10次循环后收率仍高达92%，表明GPPO HFM作为催化剂载体材料在可持续化学中具有潜在的应用前景。© 2014 Wiley Periodicals，Inc. J.应用聚合物Sci. 2015年，132，41268
Guanidylated poly(2,6-dimethyl-1,4-phenylene oxide) (GPPO) hollow fiber membrane (HFM) supported Au nanoparticles are prepared by a simple adsorption-reduction of Au3+ with sodium borohydride as a reducing agent and polyvinyl pyrrolidone as a dispersant. The novel heterogeneous catalyst shows high catalytic activity for the reduction of various aromatic nitro compounds in an aqueous medium at room temperature and can be easily reused for several runs, for example, for the reduction of nitrobenzene, the yield reaches up to 92% even after 10 cycles, indicating the potential application of GPPO HFM as a catalysts support material for sustainable chemistry. © 2014 Wiley Periodicals, Inc.
