专利号:WO-2024224841-A1 优先权日:2023-04-27 标 题 :Method for manufacturing anode for fluorine gas electrolytic synthesis 发明人:FUKUCHI Yohsuke; TO KATSUAKI; KOBAYASHI HIROSHI; OGURO Shinya 权利人:RESONAC CORP 摘要:Provided is a method for manufacturing an anode in which an anode effect does not easily occur, even if used when electrolyzing an electrolytic solution containing hydrogen fluoride and a metal fluoride to electrolytically synthesize fluorine gas. The method for manufacturing an anode for electrolytic synthesis of fluorine gas comprises a positive polarization treatment step. In the positive polarization treatment step, an anode base material having a carbon material is immersed as an anode (21) in a mixed liquid (10) for anode production, the mixed liquid (10) containing hydrogen fluoride, a metal fluoride, and potassium hexafluoronickelate(IV) together with immersing a cathode (22) therein, a current is passed between the anode (21) and the cathode (22) to subject the anode base material to a positive polarization treatment, and nickel fluoride is caused to adhere to the surface of the anode base material.
专利号:US-2020269323-A1 优先权日:2016-06-02 标题 :Synthesis of ultra-thin metal nanowires using organic free radicals 发明人:YANG PEIDONG; CUI FAN; DOU LETIAN; NIU ZHIQIANG 权利人:UNIV CALIFORNIA 摘要:Provided are methods for synthesizing metal nanowires in solution using an organic reducing agent. A reaction mixture can be provided in solution with a metal salt, the organic reducing agent, and a solvent, where the solvent includes a surface ligand or consists of a surface ligand. The organic reducing agent, such as benzoin, can be decomposed in the reaction mixture to form organic free radicals that reduce metal ions of the metal salt into metal. The surface ligand of the solvent can coordinate with the metal in a manner so that metal nanowires are formed in solution. The diameter and morphology of the nanowires, reaction speed, reaction yield, and other features may be tunable by adjusting parameters such as reaction temperature and chemistry of the reducing agent.
