以不同碳源和不同金属硝酸盐为原料,采用膨胀法分别制备了不同碳源的不同金属纳米颗粒/多孔碳纳米复合材料。重点对不同碳源的银纳米颗粒/多孔碳复合材料的微观形貌、结构、组成等进行了表征;同时,对不同碳源的银纳米颗粒/多孔碳复合材料进行了无酶H₂O₂电化学传感器的性能研究,讨论了其作为无酶H₂O₂电化学传感器的可行性。在此基础上,对通用型金属/多孔碳复合材料的性能进行了研究。

Different metal nanoparticles/porous carbon nanocomposites with different carbon sources and metal nitrates are prepared via the expansion method.The microstructure,structure,and composition of silver nanoparticles/porous carbon composites with different carbon sources are characterized.Meanwhile,the performance of enzyme-free H₂O₂ electrochemical sensors is studied upon silver nanoparticles/porous carbon composite materials with different carbon sources,and the feasibility of using them as enzyme-free H₂O₂ electrochemical sensors is discussed.On this basis,the performance of universal metal/porous carbon composites is studied.
