One pot synthesis of CeO2 nanoparticles on a carbon surface for the practical determination of paracetamol content in real samples

摘要

Using the effect of interactions between metal oxides and carbon materials is considered an attractive way to make novel composites for electrochemical sensor applications. Both metal oxides and carbon materials have good electrocatalytic properties that can be used for the sensing of different components such as organic/inorganic pollutants, drugs and molecules. These sugar base-derived carbon decorated with CeO2 nanoparticles (CeO2-C) was prepared using a one pot synthesis and used for the electrochemical sensing of paracetamol (PA). The as-prepared CeO2-C was characterized using different techniques and electrochemical studies. The resulting calculated values of sensitivity, linear range and limit of detection were 262 mu A mM(-1) cm(-2), 1 mu M to 1.2 mM and 0.07 mu M, respectively. Eventually, CeO2-C is predicted to be a suitably active material for practical applications.
