摘要：
The synthesis of polyaniline/platinum microelectrodes (PPME) have been achieved for the first time by using the controlled electrochemical reduction of PtCl62-. First, the PANI film was electrochemical prepared on the glass carbon electrode (GCE) surface by using the method of CV. It was found that the PANI film is composed of 100-200 nm diameter rods. Then, the electrochemical reduction of PtCl62- on the PANI modified surface was carried out and Pt particle was about 300-600 nm in diameter on the end of PANI membranes. Electrochemical experiments show that the microelectrodes have superior catalytic performance toward formaldehyde and methanol electrochemical oxidation. (C) 2013 Elsevier Ltd. All rights reserved.
