摘要：
CuO nanoparticles with leaf-like microstructure have been obtained by cetyltrimethylammonium bromide-assisted microwave synthesis. They have been characterized by powder X-ray and selected area electron diffractions, scanning and transmission electron microscopies and energy dispersive X-ray and electrochemical impedance spectroscopies. The synthesized leaf-like CuO deposited on graphite electrode nonenzymatically senses glucose efficiently. Cyclic voltammetic and chronoamperometric studies reveal the excellent electrocatalytic activity of leaf-like CuO towards direct glucose oxidation. The leaf-like CuO exhibits very high sensitivity (17.3 mu A mu M-1 cm(-2)) towards amperonnetric determination of glucose and glucose as low as 2 mu M could be estimated.
