铋酞菁的制备及电催化CO2还原性能研究

Preparation of Phthalocyanine-ruthenium Catalyst and its Electrocatalytic Performance for CO2 Reduction

采用溶剂热法合成了铋酞菁催化剂,用扫描电子显微镜(SEM)、X射线衍射(XRD)对制备的催化剂进行表征。将铋酞菁修饰在玻碳电极上作为电催化还原CO2的电催化剂,还原产物HCOO-在-0.8~1.3V的电势范围内(vs RHE),具有较高的浓度和法拉第效率(FE);在低电位-0.8V(vs RHE)下电解6h,FE高达81%。

Catalyst was an important component of electrocatalytic reduction of CO2.Lanthanum phthalocyanine was a catalyst with high selectivity for CO2 reduction products.The phthalocyanine ruthenium material was synthesized by solvothermal method and characterized by scanning electron microscopy(SEM).The phthalocyanine ruthenium was supported on the glassy carbon electrode by the dropping method,and it was found by electrochemical performance test that when the synthesized phthalocyanine ruthenium material was used as the catalytic active site,the CO2 reduction product HCOO-was in a wide potential range-0.8 V^1.3V(vs RHE)had a higher concentration and Faraday efficiency(FE).And at a low potential of-0.8V(vs RHE),electrolysis for 6h,FE was up to 82%.
