Ultrathin CdSe nanosheets: Synthesis and application in simultaneous determination of catechol and hydroquinone

Ultrathin crystalline CdSe nanosheets have been synthesized through a facile solution processes. Their application to simultaneous electrochemical determination of catechol and hydroquinone is demonstrated. The few-layer single crystalline CdSe modified electrode exhibits strong electrocatalytic activity toward the oxidation of a mixture of catechol and hydroquinone. The excellent analytical performance makes the ultrathin CdSe nanomaterials promising for the development of electrochemical sensors for potential applications in medicine, biotechnology and environmental chemistry.
