用伏安电荷容量表征了聚合前驱体法制备的Ti/TiO2电极的热分解温度和热分解时间对电极电催化活性的影响,用XRD,ESEM,TEM 对所制电极的表面结构、形貌及TiO2的粒径进行了表征。实验结果表明:热分解温度和热分解时间对Ti/TiO2 电极的伏安电荷容量有显著的影响,在热分解温度低于500℃时,延长热分解时间有利于提高电极的电催化活性。热分解反应温度大于500℃后,增长热分解时间,电极的电催化活性减小。不同热分解温度和热分解时间下所形成的不同的电极表面结构和形貌影响了Ti/TiO2电极的电催化活性。
The effect of thermal decomposition temperature and thermal decomposition time on the electrocatalytic activity of Ti / TiO2 electrode was characterized by voltammetric charge capacity. The surface structure, morphology and morphology of the electrode were characterized by XRD, ESEM and TEM. The particle size of TiO2 was characterized. The experimental results show that the thermal decomposition temperature and thermal decomposition time have a significant effect on the voltammetric charge capacity of Ti / TiO2 electrode. When the thermal decomposition temperature is below 500 ℃, prolonging the thermal decomposition time is beneficial to improve the electrocatalytic activity of the electrode. Thermal decomposition reaction temperature is greater than 500 ℃, the thermal decomposition time increases, the electrode electrocatalytic activity decreases. Different electrode surface structures and morphology formed under different thermal decomposition temperature and thermal decomposition time affected the electrocatalytic activity of Ti / TiO2 electrode.
