Preparation of Pt Colloids via a Wet-Chemical Method for Methanol Sensor

Abstract:

Article Preview

Pt colloids were synthesized by a wet-chemical method. The Pt colloids were modified on the glassy carbon electrode (GCE). The electrochemical behavior and electrocatalyst for methanol of the colloidal Pt-modified electrode in H2SO4 medium were investigated. The results show that the as-prepared Pt colloids are good electrocatalysts for methanol oxidation and the oxidation current increases with methanol concentration in the range of 0.002 to 0.5 M. The colloidal Pt-modified electrode is simple, easy-to-use and reusable, showing promising applications in the electrocatalyst and determination of methanol.
