摘要: 杂多酸基纳米复合材料在光电催化、生物传感器件等方面有较好的应用前景,其合成方法简单、环保,催化性能良好。利用杂多酸同时作为包覆剂、还原剂和链接剂制备银纳米粒子@多酸-碳纳米管三元纳米复合材料,该材料可以提高修饰电极的抗甲醇干扰性,且具有很高的电催化氧气还原反应(ORR)活性。利用原位还原方法同时还原金属离子与氧化石墨,制备出包括金、铂、钯纳米粒子等贵金属纳米粒子@多酸-石墨烯以及银纳米网@多酸-石墨烯三元纳米复合材料,可作为良好的生物传感材料和燃料电池电极材料。利用高温NH3 处理制备银纳米粒子@多酸-氮掺杂石墨炔三元纳米复合材料,可实现无金属高活性ORR电催化。

Abstract: The heteropolyacid nano enviromental composite materials have good application prospect in photoelectric catalysis and biosensor domain. The synthesis method is simple,enviromental,and has good catalytic performance. With solely polyoxometalates(POMs) as reducing,bridging and encapsulating molecules, obtained Ag nanoparticles NPs- decorated carbon nanotubes (CNTs).The modified electrode resisted the methanol interference,and had very high electrocatalytic oxygen reduction activity;The synthesis of metal nanostructures Au NPs,Pt NPs,Pd NPs and Ag nanonet(NN)- decorated graphene nanosheets(GNSs) have been reported,they can be used as good biological sensing materials and fuel cell electrode materials. Under high temperature with NH3,Ag nanoparticles(NPs) @POMs-decorated graphdiyne was prepared,realized non-metal high electrocatalytic oxygen reduction activity.

Key words: photoelectrocatalysis, nanohybrids, polyoxometalates, noble metal, graphene, graphdiyne
