甲醛在聚苯胺载铂电极上的电催化氧化
Electrocatalytic Oxidation of Formaldehyde on Platinum Load on Polyaniline Electrode
摘要
Abstract
Polyaniline (PAn)was loaded on Ti-based metal electrode and platinum was loaded on polyaniline,and Pt/PAn/Ti was prepared by cyclic voltammetry (CV)and was characterized by SEM and CV.Electrocatalytic oxidation of formaldehyde on platinum load on polyaniline electrode was investigated by reseaching the electrocatalytic oxidation of formaldehyde on Pt/PAn/Ti electrode.The result shows that electrocatalytic oxidation of formaldehyde was related with the quantity of platinum microparticles. Platinum microparticles were dispersed better, showing bigger effective area. Compared with that of the Pt/Ti electrode with the same quantity of platinum deposited,the peak current of formaldehyde in the positive scanning was increased 2.3 times and oxidation potential was negatively shifted by about 40 mV on Pt/PAn/Ti electrode.The peak current of formaldehyde in the negative scanning was increased about 5 times and oxidation potential was negatively shifted by about 30 mV.At the same time,the result shows,too that the oxidation peak in the positive scanning was controlled by liquid phase mass transfer process and the oxidation peak in the negative scanning was controlled by adsorption behavior.关键词
