摘要
用电纺丝技术和加热交联技术制备了聚乙烯吡咯烷酮(PVP)负载纳米钯的纳米丝状催化剂PVP-Pd,并对所制备的催化剂进行了SEM,TEM,UV和TG的表征。利用PVP-Pd对烯烃和硝基苯的催化氢化反应研究了所制备催化剂的催化性能,结果表明纳米纤维态PVP-Pd催化剂在室温、氢气条件下催化氢化α-辛烯和环己烯的转化率可以达到100%,对硝基苯也有很好的催化活性。
Catalytic palladium nanoparticles fibrous mophology via electrospinning and on polyvinylpyrrolidone were prepared bearing a nano-heat cross-linking technique, the title catalyst was characterized by SEM, TEM, UV and TG. The catalytic property was evaluated by hydrogenation of α-octene, cyclohexene and nitrobenzene in ethanol and the yield of octane and cyclohexane reached up to 100% at normal temperature and under hydrogen pressure.
