Abstract: The present disclosure discloses an ABO3 type high-entropy perovskite Bax(FeCoNiZrY)0.2O3-δ electrocatalytic material and a preparation method thereof, belonging to the technical field of electrocatalytic materials. The electrocatalytic material is prepared by taking hydrated cobalt nitrate, hydrated ferric nitrate, hydrated nickel nitrate, barium nitrate, hydrated yttrium nitrate, hydrated zirconium nitrate and polyacrylonitrile staple fibers as raw materials through processes of liquid phase chelation, gelation, calcination, etc. The prepared high-entropy perovskite Bax(FeCoNiZrY)0.2O3-δ electrocatalytic material can release more electrochemical active sites due to its special nanostructure, thus showing better electrocatalytic activity. Meanwhile, by adjusting the stoichiometric ratio of A/B-site metals, the electronic structure change of five metals in a catalytic center and the change of an oxygen vacancy content are realized, and the purpose of adjusting and optimizing the nitrogen reduction performance is achieved, so that the electrocatalytic material has excellent electrocatalytic conversion of nitrogen gas into ammonia gas.

Abstract: Electrosynthesis of oxirane can include contacting a halide electrolyte with an anode and cathode respectively located in anodic and cathodic compartments; supplying olefin reactants into the electrolyte in the anodic compartment, such that the anode generates ethylene chlorohydrin; withdrawing a loaded anodic solution comprising ethylene halohydrin from the anodic compartment, and a loaded cathodic solution comprising OH- ions from the cathodic compartment; and mixing the loaded anodic solution with the loaded cathodic solution under conditions to react ethylene halohydrin with OH- to produce oxirane. The electrocatalyst can include iridium oxide on a titanium substrate, with the iridium oxide provided as nanoparticles on a titanium mesh, and the electrolyte can be aqueous KCl. The electrocatalyst can define an extended heterogenous:homogenous interface with halide ions acting as a reservoir for positive charges, thereby storing and redistributing positive charges to promote selective generation of ethylene halohydrins.
