Problems solved by technology

Therefore, the type of surface material and the preparation process have a decisive effect on the catalytic activity of the three-dimensional electrocatalytic electrode; at the same time, because the connection effect between the carrier and the surface material is difficult to control, the catalytic effect of the formed three-dimensional electrocatalytic electrode is likely to be unstable. , and the catalytic lifetime is not long enough

Embodiment 1

[0046] Embodiment 1: a grid type electrocatalytic oxidation catalytic material, prepared by the following steps:

[0047] S1, the clinoptilolite raw material is screened, washed, wet-milled, precipitated, air-dried, calcined in a muffle furnace at 400° C. for 2 hours, and cooled to obtain clinoptilolite powder;

[0048] S2, the clinoptilolite powder obtained in step S1 is fully immersed in a sodium chloride solution with a concentration of 1.0 mol / L, mechanically stirred for 5 hours in a water bath at 70°C, filtered and washed with pure water until no chloride ions are present Detected, placed in an oven and dried at a temperature of 108 ° C to obtain activated clinoptilolite powder;

[0049] S3, the Ce (NO 3 ) 3 ·6H 2 O, 4.4-10.9 parts of FeCl 3 , 0.87-2.77 parts of SnC l4 , dissolved in 100mL of pure water, and mixed thoroughly to form an immersion solution;

[0050] S4, take 100 parts of the activated clinoptilolite powder obtained in step S2 and add it to the immersi...

Embodiment 2

[0052] Example 2: A grid-type electrocatalytic oxidation catalytic material, the difference from Example 1 is that, in step S1, the clinoptilolite raw material is calcined in a muffle furnace at a temperature of 300°C and a calcination time of 3h.

Embodiment 3

[0053] Example 3: A grid-type electrocatalytic oxidation catalytic material, the difference from Example 1 is that in step S1, the temperature of calcining the clinoptilolite raw material in a muffle furnace is 100°C, and the calcining time is 4h.

Abstract

The invention discloses a grid-type electrocatalytic oxidation catalytic material and a preparation process thereof. The grid-type electrocatalytic oxidation catalytic material comprises clinoptilolite and a metal oxide coated on the outer surface of the clinoptilolite. The parts by weight of clinoptilolite are 100 parts; the metal oxides include the following parts by parts by weight: 3.5-7.2 parts of cerium oxide; 1.5-3.8 parts of ferric oxide; 0.5-1.6 parts of tin dioxide. The invention has the advantages of high catalytic activity, good stability and reproducibility.

Description

technical field [0001] The invention relates to the technical field of electrocatalytic catalyst fillers, and more particularly, to a grid-type electrocatalytic oxidation catalytic material and a preparation process thereof. Background technique [0002] Wastewater usually contains a large amount of organic substances that are difficult to be degraded. Using electrocatalytic oxidation technology, under the action of an electric field, the modifiers existing on the electrode surface or in the solution phase can promote or inhibit the electron transfer reaction that occurs on the electrode. The modification itself does not change on the surface or in the solution phase, thereby degrading the organic matter in the wastewater. Catalytic electrodes are mainly divided into two-dimensional electrocatalytic electrodes and three-dimensional electrocatalytic electrodes. [0003] Traditional two-dimensional electrocatalytic electrodes have a certain effect on the treatment of toxic, h...
