[EMIM][BF4]离子液体电解质中nano-TiO2/Ti电催化还原CO2性能的研究
Research of Nano-TiO2/Ti Electrode for Electrochemical Reduction of CO2 in Ionic Liquid [EMIM4 ][BF4 ]System
摘要
Abstract
In this paper,the highly pure Ti plate was used as the electrode substrate.Nano-TiO2/Ti thin film electrode was prepared by anodic oxidation and high temperature treatment technology.X-ray diffraction (XRD),scanning electron microscopy (SEM) and other physical characterization results show that nano-TiO2 is anatase crystal,morphology is presented as a nanotube array with uniform diameter,the diameter of the tube is about 100 nm,and the wall thickness is about 5 nm.In the ionic liquid water mixing system ([EMIM][BF4 ]-H2O),cyclic voltammetry (CV) was used to characterize the electrocatalytic performance of nano-TiO2/Ti electrode for electrocatalytic reduction of CO2 .The test results show that nano-TiO2 has a high catalytic activity for electrocatalytic reduction of CO2 presumably to HCOOH,CH3OH and other small molecular organic compounds.关键词
