摘要： An electrode for gas evolution in electrolytic processes and a method for the production of such an electrode, the electrode having a metal substrate and a coating formed on the substrate, wherein the coating has at least a highly porous catalytic outer layer containing nickel oxide and nickel hydroxide, the porous outer layer having a surface area of at least 40 m2/g (BET). The catalytic layer is prepared from a Ni oxide/V oxide initial coating with subsequent leaching of V.

摘要： A method for making an electrocatalyst containing manganese oxide nanoparticles present on carbon obtained from Albizia procera (MnOxNPs-C) for electrochemical water oxidation. The method includes a thermal decomposition and forms a product with specific morphological variations, including crystalline structure, elemental composition, and chemical compatibility. The manganese oxide nanoparticles are well dispersed over the carbon. The amount of manganese oxide nanoparticles increases by increasing the amount of precursor. Single-phase formation of the Mn3O4, and Mn3O4 along with MnO phase occurs at low and high amount of the precursor materials, respectively. The electrocatalyst can be used for the purpose electrolytic water splitting.

摘要： A method of forming a hydrocarbon product and hydrogen gas comprises introducing CH4 to a positive electrode of an electrochemical cell comprising the positive electrode, a negative electrode, and a proton-conducting membrane between the positive electrode and the negative electrode. The proton-conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10−2 S/cm at one or more temperatures within a range of from about 150° C. to about 600° C. A potential difference is applied between the positive electrode and the negative electrode of the electrochemical cell to produce the hydrocarbon product and the hydrogen gas. A CH4 activation system and an electrochemical cell are also described.
