Abstract
AbstractThe novel nanoparticles, [Ru(bpy)3]2SiW12O40⋅2 H2O, were firstly synthesized and characterized by elemental analysis, IR, and TEM. The nanoparticles were used to fabricate a chemically modified carbon paste electrode (CPE) by dispersing nanoparticles and graphite powder in silicone grease. Thus‐prepared CPE shows bifunctional electrocatalytic activities towards the reduction of nitrite and the oxidation of oxalate, and exhibits sensitive electrochemiluminescence (ECL). The modified CPE has high stability and excellent repeatability owing to the insolubility and homogeneous disperses of the nanoparticles. The nanoparticles modified CPE may open a way to be used as solid electrochemical sensor for both ECL and electrocatalysis in practical applications.
