Abstract
The electrochemistry and electrochemiluminescence (ECL) of novel three-dimensional nanostructured Ru(bpy)32+/Ni(OH)2 microspheres were investigated for the first time. The negatively charged porous Ni(OH)2 microspheres composed of Ni(OH)2 nanowires were specifically designed to interact with Ru(bpy)32+. The large surface area and porous structure of Ni(OH)2 microspheres enhance loading of Ru(bpy)32+ and mass transport of the model analyte, tripropylamine (TPA). Excellent ECL performance of the presented sensor was achieved including good stability and wide linear range from 7.7 × 10−10 to 3.8 × 10−3 M with the detection limit of 2.6 × 10−10 M to TPA.
