| 摘 要： | 在旋涂有球状纳米TiO2薄膜的导电玻璃(ITO)基底上采用循环伏安法(CV)电沉积RuO2作为电催化还原CO2的阴极.采用场发射扫描电子显微镜(FE-SEM)表征了RuO2/TiO2纳米薄膜的形貌,并应用近稳态电位扫描法和计时电流法(i～t)研究了薄膜的电催化CO2性能.结果表明所构建的RuO2/TiO2薄膜中纳米粒子大小均匀、排列致密,且较传统热分解法所得催化剂有更好的电催化性能.

| Abstract: | RuO_2 electrodeposited on spherical-TiO_2 nanoparticles-spin-coated ITO substrate by using cyclic voltammetry (CV) was used as the cathode for electrocatalytic reduction of CO_2. The surface morphology of the as-prepared film was characterized by field emission scanning electron microscopy (FE-SEM) and its electrocatalytic performance was assessed by quasi-steady-state potentiodynamics and chronoamperometry (i～t). The results show that the as-prepared RuO_2/TiO_2 nanofilm consists of uniform and compact nanoparticles, exhibiting superior electrocatalytic activity and stability for electrochemical reduction of CO_2 as compared to that prepared by traditional thermal decomposition. |
