Abstract

The invention discloses a preparation method of a novel flower-like basic copper chloride catalyst. The preparation method comprises the following steps: preparing a sodium hydroxide aqueous solution, namely preparing the sodium hydroxide aqueous solution with the concentration being 0.32-0.8mol / L; dissolving at the room temperature: adding copper chloride and 30% hydrogen peroxide to the sodium hydroxide aqueous solution to prepare a mixed solution with a copper chloride concentration being 0.154-0.164mol / L, and with the ratio of the additive amount of the 30% hydrogen peroxide to the volume of the sodium hydroxide aqueous solution being 1:(1-25); and carrying out hydrothermal reaction, namely adding the mixed solution to a polytetrafluoroethylene lining, carrying out hydrothermal reaction at the constant temperature of 80-140 DEG C for 18-24 hours, centrifuging, washing and drying. The method is simple and feasible, and easy to promote, compared with methods reported by documents, the method has the advantages that the flower-like basic copper chloride catalyst with high activity can be prepared, and can be used for catalytic degradation of organic pollutants.

Description

technical field [0001] The invention relates to the field of catalyst preparation, in particular to a preparation method of a novel flower-shaped basic copper chloride catalyst. Background technique [0002] In 1893, chemist Fenton HJ discovered that hydrogen peroxide (H 2 o 2 ) and ferrous ions have strong oxidizing properties, and can oxidize many known organic compounds such as carboxylic acids, alcohols, and esters to inorganic states at that time, and the oxidation effect is very significant. However, for more than half a century since then, this oxidizing agent has not received much attention because of its strong oxidizing properties. Entering the 1970s, Fenton's reagent found its place in environmental chemistry. Fenton's reagent, which has a high ability to remove refractory organic pollutants, has been widely used in the treatment of printing and dyeing wastewater, oily wastewater, phenolic wastewater, coking wastewater, nitrobenzene-containing wastewater, and d...
