The invention relates to a graphene aerogel electrode material loaded with copper ions. The diffraction angle 2 theta of the crystal form has diffraction peaks at 29.689 +/- 0.2 degrees, 36.547 +/- 0.2 degrees, 42.484 +/- 0.2 degrees, 52.686 +/- 0.2 degrees, 61.646 +/- 0.2 degrees, 73.858 +/- 0.2 degrees and 77.738 +/- 0.2 degrees. The graphene aerogel electrode material provided by the invention has ultrahigh adsorption capacity to organic dyestuff wastewater, is capable of assisting in promoting electricity-fenton reaction efficiency and is capable of effectively avoiding iron sludge generation; the graphene aerogel electrode material loaded with copper ions applied to the electricity-fenton system not only can keep high degradation rate under the condition of pH equal to 3 but also can keep higher degradation rate under the condition of pH equal to 7; the excellent electrical conductivity of the graphene aerogel can effectively increase the transfer rate of the electrons on the surface of the graphene aerogel electrode material loaded with copper ions and can further accelerate the continuous in-situ generation of H2O2 at cathode; H2O2 also reacts with an electrode-loaded copper ionic catalyst so as to generate. OH, so that stable high efficiency in the electricity-fenton process can be kept.
