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 making a supercapacitor including mixing aniline and an acid to form a solution, contacting a reference electrode, a counter electrode, and a steel substrate with the solution to form an electrodeposition system, applying a potential of from greater than 0 to about 2 volts (V) to the electrodeposition system, and depositing particles of polyaniline on a surface of the steel substrate to form a polyaniline electrode. The particles of the polyaniline have an oval sheet morphology with an average length of 100-300 nanometers (nm) and an average width of 50-150 nm. The method includes assembling two of the polyaniline electrodes in a symmetrical layered configuration with the surfaces having the particles of the polyaniline facing each other. An electrolyte is present between the two polyaniline electrodes to form the supercapacitor.

摘要： An asymmetric nanocomposite supercapacitor and a method of making the asymmetric nanocomposite supercapacitor. The asymmetric nanocomposite supercapacitor includes a negative electrode with monoclinic tungsten oxide (m-WO3) nanoplates, and a binding compound coated on one face of a substrate, and a positive electrode with a carbonaceous material and a binding compound coated on one face of a substrate. Where the face of the positive electrode and the face of the negative electrode coated with the carbonaceous material and m-WO3 nanoplates, respectively, are separated by and in direct contact with a porous separator.
