Summary: | The invention discloses a coal liquefaction residue electrode as well as a preparation method and application thereof. The preparation method of the coal liquefaction residue electrode comprises the following steps: (1) mixing 1-7 parts by weight of coal liquefaction residue coke, 1-4 parts by weight of graphite and 1-4 parts by weight of coal liquefaction residue to form a mixture; wherein the coal liquefaction residue coke is obtained by deashing coal liquefaction residues and treating the coal liquefaction residues with an additive; (2) carrying out hot press molding on the mixture at 100-500 DEG C to obtain an electrode green body; and (3) pyrolyzing the green body in an inert atmosphere at a temperature range of 500-1300 DEG C to obtain the coal liquefaction residue electrode. According to the method, the coal liquefaction residues are structurally regulated and controlled by a proper modification method, a dual-function electrode for producing CO through carbon-water reaction of an anode and producing H |
