Abstract Among nano polyaniline materials, polyaniline nanofibers are the most important. The low conductivity and poor processability have become the biggest obstacles to the application of polyaniline as a practical material. The excellent characteristics of new polyaniline nanofiber materials can just overcome the shortcomings of Polyaniline in forming and processing. In this study, a new polyaniline nanofiber was prepared by chemical oxidation, its structure was characterized, the mechanism of improving its conductivity was studied, and its superior electrocatalytic activity was evaluated by Electrochemical performance test. The results show that the diameter of polyaniline nanofibers is 20nm ~ 50nm and the fiber length is 2µm ~ 5µm. The structure is uniform and the conductivity can reach 13.5 S/cm. he electrocatalytic activity of polyaniline nanofibers for oxygen evolution and chlorine evolution was systematically tested. It was found that the electrocatalytic activity of polyaniline nanofibers for oxygen evolution was higher than that of polyaniline nanofibers. The electrocatalytic activity of carbon paper electrode prepared by β-PbO2 nano powder is superior to that of traditional chlorine evolution anode Ti/RuO2.

Combinatorial synthesis combined with high throughput electrochemistry enabled discovery of 29 ternary oxide photoanodes, 14 with visible light response for oxygen evolution. Y3Fe5O12 and trigonal V2CoO6 emerge as particularly promising candidates due to their photorepsonse at sub-2.4 eV illumination.
