Latest Patents

Ohkuni holds a patent for a "Porous carbon and method of manufacturing same." This invention provides a method to inhibit the oxidation of metal particles while maintaining their effectiveness over time. The process involves mixing a polyamic acid resin varnish as a carbon precursor, magnesium oxide as template particles, and chloroplatinic acid as a metal salt. The mixture is then heat-treated in a nitrogen atmosphere at 1000°C for one hour, which reduces the chloroplatinic acid into platinum and thermally decomposes the polyamic acid resin to prepare carbon containing platinum particles. Finally, the resulting carbon is washed with a sulfuric acid solution to completely dissolve the magnesium oxide.
