The invention discloses an activated (Cu-Fe-Ce) / Al2O3 nanoparticle electrode. The activated (Cu-Fe-Ce) / Al2O3 nanoparticle electrode is prepared with an impregnation method, then reduced with 10% sodium borohydride, so that a primary battery like structure is formed on the surface of an activated Al2O3 carrier, electron transfer and capture are accelerated under the action of an external electric field, so that a catalytic oxidation reaction of organic pollutants on the surface of the nanoparticle electrode is enhanced. The nanoparticle electrode utilizes the high specific surface area (280-360m<2> / g) of activated Al2O3, the capacity of active components in the nanoparticle electrode is increased, and the catalytic oxidation activity of the nanoparticle electrode is improved. The inventionalso discloses a preparation method of the nanoparticle electrode.

Description

technical field [0001] The invention relates to the technical field of electrochemical catalytic oxidation, in particular to an activated (Cu-Fe-Ce) / Al 2 o 3 Preparation and application of nanoparticle electrodes. Background technique [0002] Electroplating is a process that uses electrochemical methods to decorate, protect and obtain certain new properties on metal and non-metal surfaces. In order to ensure the quality of electroplating products, the metal coating has a smooth and good appearance and is firmly bonded to the substrate. In combination, the dirt (oil, rust, scale, etc.) on the surface of the plated parts must be thoroughly cleaned before plating, and the adhesion liquid on the surface of the plated parts must be cleaned after plating. Therefore, a large amount of waste water must be discharged in the general electroplating production process. Electroplating wastewater, especially comprehensive electroplating wastewater, has the characteristics of many type...

Problems solved by technology

However, the traditional electrocatalytic catalytic oxidation technology has two defects: first, when two-dimensional electrodes are used, the current efficiency is low, the chemical reaction is slow, and the power consumption is high, so it is not suitable for electroplating wastewater tail water treatment with relatively low budget cost; The second is the existing improved technology. Generally, the anode is made into a three-dimensional structure to improve the catalytic activity of the reaction, but the manufacturing cost is high, and the surface of the electrode is easily blocked by pollutants, resulting in the failure of catalytic activity.
