摘要
利用二氧化锰(MnO2)纳米材料新颖的化学、物理特性,研究其对三联吡啶钌(Ru(bpy)3^2+的电致化学发光(ECL)的催化作用,结果发现,纳米MnO2材料在温和的条件且较正的电位(+O.4V(VS.Ag/AgCl))下可以催化Ru(bpy)33^2+产生阴极ECL。同时推导了其催化机理,为制备一种新型的高灵敏度的ECLSensor奠定了理论基础。
MnO2 nanomaterials showed novel chemical and physical properties because of their special structure, and the corresponding chemiluminescence (ECL) catalysis of Terpyridine ruthenium were investigated. The results indicate that a novel cathodic ECL of Ru(bpy)33^2+ would be appeared at positive potential of +0.4V(vs. Ag/AgCl) and mild conditions. In this paper, catalytic mechanism of MnO2 nanomaterials was deduced and a theoretical basis for preparing novel ECL Sensor with high sensitivity was provided.
