Abstract:
1. A method for electrolytic synthesis of a fluorine-containing material using a conductive diamond electrode structure with a fluoride ion-containing molten salt electrolytic bath, which conductive diamond electrode structure comprises: a conductive electrode feeder; and a conductive diamond catalyst carrier comprising a conductive substrate and a conductive diamond film carried on a surface thereof, wherein the conductive electrode feeder is exposed at an upper portion, not to be immersed in the electrolytic bath, to a gas zone containing a fluorine gas or a fluoride gas generated by performing electrolysis, wherein the conductive diamond catalyst carrier is detachably attached to the conductive electrode feeder at a lower portion, to be immersed in the electrolytic bath, wherein the conductive electrode feeder comprises any one of a conductive carbonaceous material, nickel and a nickel-copper alloy, wherein the conductive diamond catalyst carrier is detachably attached to the conductive electrode feeder with a screw or with a bolt and a nut, and wherein the screw or the bolt and nut comprises any one of a conductive carbonaceous material, nickel and a nickel-copper alloy, said method comprising: holding the conductive diamond electrode structure so that at the portion to be immersed of the conductive electrode feeder, the conductive diamond catalyst carrier is immersed in a fluoride ion-containing molten salt electrolytic bath while an upper portion of the conductive electrode feeder remains exposed to the gas zone containing a fluorine gas or a fluoride gas generated by performing electrolysis, and performing electrolysis, thereby electrolytically synthesizing a fluorine-containing material.
