Embodiment 1

[0050] The added mixed solution contains a concentration of 0.5mol L -1 Hydrogen peroxide, the pH value of the solution is 3.85, and the catalyst is YMn 2 o 5 , for hydrogen peroxide catalysis, the dosage is 50mg, the solution volume is 50ml, and the reaction temperature is 25°C. The decomposition performance of hydrogen peroxide is expressed by the ratio of the real-time concentration of hydrogen peroxide to its initial concentration. The test results are shown in image 3 . The results showed that 100% decomposition of hydrogen peroxide could be achieved within 1 hour under the same conditions.

Embodiment 2

[0052] In order to illustrate the effect of the catalyst on the decomposition of hydrogen peroxide, a blank experiment was done without adding the catalyst. The added mixed solution contains a concentration of 0.5mol L -1 Hydrogen peroxide, the pH value of the solution is 3.85, used for the self-decomposition of hydrogen peroxide, the solution volume is 50ml, the reaction temperature is 25°C, the decomposition performance of hydrogen peroxide is expressed by the ratio of the real-time concentration of hydrogen peroxide to its initial concentration, see test results Figure 4 . The results showed that the degradation effect of hydrogen peroxide itself was negligible within 3 hours at room temperature.

Embodiment 3

[0054] In order to explore the influence of the carrier on the catalytic performance of hydrogen peroxide, the YMn 2 o 5 Loaded on TiO with the carrier according to the mass ratio of 1:1 2 and Al 2 o 3 Above, composite catalysts 1 and 2 were obtained for hydrogen peroxide catalysis, the dosages of composite catalysts 1 and 2 were both 50 mg, and the concentration of hydrogen peroxide was 0.5mol L -1 , the pH value of the solution is 3.85, the solution volume is 50ml, and the reaction temperature is 25°C. The conversion rate of hydrogen peroxide is represented by the consumption rate of hydrogen peroxide. Each test lasts at least 3 hours. The test results are shown in Table 1. The results showed that both the catalyst and TiO 2 The composite catalyst 1 obtained by loading is still with Al 2 o 3 With the obtained composite catalyst 2 loaded, the purification efficiency of hydrogen peroxide remained at 100% under the experimental conditions.

Abstract

The invention provides an application of a compound with a general formula AM2O5-x in catalyzing hydrogen peroxide at room temperature, a catalyst provided by the invention is mullite type composite oxide AM2O5-x, A is any one or more of lanthanide series metal elements, Sm, Bi and Y, M is any one or more of first transition series transition metal elements, and x is between 0 and 1. The compound with the general formula AM2O5-x has an excellent effect of catalytically decomposing gas-phase and / or liquid-phase hydrogen peroxide at room temperature; the catalyst has two coordination units taking transition metals as centers, and the coordination oxygen activity is higher, so that the catalyst has extremely high stability when being used for treating gas-phase and / or liquid-phase hydrogen peroxide at room temperature, and the service life is very long; the AM2O5-x compound does not contain noble metal, so that the cost is relatively low; meanwhile, the preparation method of the compound is relatively mature and simple in the prior art, so that mass production can be performed for large-scale hydrogen peroxide decomposition treatment; furthermore, through experimental verification, the device can be suitable for hydrogen peroxide treatment in different industries and under various environmental conditions.

Description

technical field [0001] The present invention relates to the technical field of hydrogen peroxide treatment, in particular to a general formula AM 2 o 5-x Application of the compound as a catalyst for the catalytic decomposition of hydrogen peroxide at room temperature. Background technique [0002] Pure hydrogen peroxide is a light blue viscous liquid with weak reducing and strong oxidizing properties. Its decomposition products are water and oxygen. It is non-toxic and harmless and will not introduce impurities into the system. Therefore, hydrogen peroxide, as a chemical product with diversified applications, has applications in pulp bleaching, textile fields, electronics industry, food industry and environmental protection fields. The growth of demand for hydrogen peroxide in various industries has stimulated the improvement of hydrogen peroxide production process, resulting in overcapacity and a significant reduction in price. The application of hydrogen peroxide has gr...
