摘　　要：采用溶胶凝胶法制备了多孔Ti/SnO_(2)-Sb-Ni电极,并研究了所制备电极的电催化产臭氧性能。采用SEM与XRD等方法对电极涂层的表面形貌及结构进行了表征;考察了不同电极基体条件对电催化产臭氧性能的影响。实验结果表明:多孔Ti/SnO_(2)-Sb-Ni电极表面呈现为密集粗糙颗粒状结构;当电极涂层中Sn∶Sb∶Ni摩尔比为500∶8∶5、泡沫钛基体孔径为20μm时,制备出的电极有最佳的电催化产臭氧性能。多孔Ti/SnO_(2)-Sb-Ni电极可为新型电化学生成臭氧技术的研究和应用提供支撑。Porous Ti/SnO_(2)-Sb-Ni electrodes were prepared by sol-gel method,and their electrocatalytic ozonation performance was investigated.The surface morphology and structure of the electrode coating were characterized by SEM and XRD.The effects of different electrode matrix conditions on ozone production by electrocatalysis were investigated.The results show that the porous Ti/SnO_(2)-Sb-Ni electrode surface presents a dense coarse granular structure.When the molar ratio of Sn:Sb:Ni in electrode coating is 500∶8∶5 and the pore size of titanium foam matrix is 20μm,the electrode has the best electrocatalytic ozone production performance.The porous Ti/SnO_(2)-Sb-Ni electrode in this paper can provide support for the research and application of novel electrochemical ozone generation technology.
