The usage of zeolite mcm-41(1)
Ordered mesopore of MCM41, which is a new type of nanosecture material. Compared with other zeolites, the skeletal Al species of MCM-41 exhibited poor thermal stability against short circuit. As a special mesoporous molecular sieve, it has been widely used in many fields, such as chemical industry, environmental protection and so on. The MCM41 load products have more new roles. M41S is a good catalyst carrier because of its ordered pore arrangement, narrow pore distribution, large specific surface area and thermal stability against short circuit.
1. Environmental Protection Field - Organic Pollution Degrade by TiO2MCM41
Advanced oxidation is an effective method for the thorough and extensive degradation of organic pollutants and bacterial substances. The use of Ti O2 as an Acidifying agent for the advanced degradation of gas and water is the most effective measure in all published chemical literature in recent years. However, Ti O2 itself has some limitations for the reaction. It has no pore channels, so it shows a low adsorption performance, especially for non-polar compounds. However, the adsorption step is an extremely important preliminary step for the reaction.
The pores of the MCM41 are between 1.87-2.25 nm. The tiO2 is supported on the MCM41, Compared with the bare TiO2, the reactivity of the catalyst is greatly improved, because the specific surface area of the supported TiO2 is increased, so that organic pollutants can accumulate on the surface of the catalyst, and the electron holes on the catalyst surface can be reduced. Related experiments have achieved some results, although the actual results are far from ideal, but researchers are still persevering in the study.
