Embodiment 1

[0030] Embodiment 1 of the present invention is: a method for preparing a copper-cerium bimetallic Fenton-like catalytic material, comprising the following steps:

[0031] 1) Precursor preparation: disperse soluble copper salt (97.5at%) and cerium salt (2.5at%) in about 80ml of water, stir evenly; add 4mol / L sodium hydroxide solution, adjust the pH of the system to 7.0, add 20ml of 0.15 The g / ml glucose solution partially reduced the metal ions, and continued stirring for 1 h to obtain a blue precursor.

[0032] 2) Hydrothermal reaction: Place the obtained precursor in a hydrothermal reaction kettle and keep it at a constant temperature of 100°C for 15 hours; after cooling to room temperature, centrifuge to obtain a precipitate, wash it with water three times, and dry it under vacuum at 65°C overnight to obtain a copper-cerium bimetallic oxide catalyst materials. The material was characterized by scanning electron microscopy, and the results were as follows: figure 1 shown, ...

Abstract

The invention discloses a preparation method of a copper-cerium bimetallic Fenton-like catalytic material, the prepared catalytic material and application of the catalytic material. The preparation method comprises the following steps: S1, preparing a precursor: adding a precipitant into a solution containing copper ions and cerium ions, adjusting the pH value of the system to be higher than 7, adding a glucose solution, and continuously stirring to obtain a blue precursor; and S2, carrying out hydrothermal reaction: putting the blue precursor prepared in the step S1 into a hydrothermal reaction kettle, carrying out solid-liquid separation on a product after the reaction is finished, and collecting a solid-phase part to obtain the catalytic material. According to the scheme, the catalyticmaterial is high in catalytic activity and can rapidly catalyze Fenton reaction to degrade organic pollutants in water, especially azole antifungal drugs.

Description

technical field [0001] The invention relates to the technical field of Fenton-like catalysts, in particular to a preparation method of a copper-cerium bimetallic Fenton-like catalytic material, the prepared catalytic material and applications thereof. Background technique [0002] With the increasing clinical application of immunosuppressants, the incidence of fungal infection is also increasing year by year. Azole drugs (including imidazoles and triazole derivatives) are a class with good prospects in antifungal drugs. Has been widely used. In addition, this class of drugs is also widely used in agricultural production and personal care products. However, because this kind of drug is difficult to be degraded, it has been regarded as a new class of environmental pollutants in recent years. However, since most conventional wastewater treatment plants do not consider how to remove such emerging pollutants, a large amount of undegraded azole antifungal drugs may be directly d...
