One pot synthesis of Ru(bpy)32+ doped graphene oxide–silica composite film for constructing high performance solid-state electrochemiluminescent sensor

The Ru(bpy)32+ doped graphene oxide–silica composite film (Ru/GO-SiCF) was synthesized by one pot hydrolysis and condensation of tetraethylorthosilicate (TEOS) in the water–alcohol solution of graphene oxide and Ru(bpy)32+ at room temperature. The prepared Ru/GO-SiCF modified glassy carbon electrode (GCE) showed excellent electrochemiluminescence (ECL) behavior for the determination of tripropylamine (TPA) with high sensitivity and good stability. We expected this simple and novel material will find further application in construction of other targets sensors.
