NOVELTY - Preparing iron (II) molybdate/graphene oxide catalytic electrode comprises (i) dissolving ferrous tetrachloride and thiourea in a molar ratio of 0.2-1:1 in deionized water, stirring to obtain a clear and transparent mixed solution a, (ii) adding ammonium molybdate into the above mixed solution and mixing to obtain mixed solution b, where molar ratio between ammonium molybdate and thiourea is 0.2:1, (iii) adding graphene oxide into the mixed solution b and stirring to obtain mixed solution c, where mass ratio between graphene oxide and thiourea is 7-30 x 10-3:1, (iv) crimping the carbon fiber cloth into a high pressure closed reactor, pouring mixed solution c into the high pressure closed reactor and sealing high pressure closed reactor, (v) heating high-pressure closed reactor at 120-240 degrees C for 6-24 hours, naturally cooling, and (vi) rinsing prepared catalytic conductive film with deionized water and then drying to obtain final product. USE - The method is useful for preparing iron (II) molybdate/graphene oxide catalytic electrode. ADVANTAGE - The electrode: has high efficiently degradating persistent organic pollutant.
