1. Product Description
The skeleton composition of MCM-41 is not limited to silicoaluminates, but can also be phosphates, silicon oxides, transition metals, and even semiconductors. In addition, B, Ti, Fe, Mn, Ga, V, Zr, Co, and La plasma can be added through doping to obtain certain physical and chemical properties. Therefore, the chemical composition of MCM-41 has the characteristics of diversity and controllability.
MCM-41 is an ordered mesoporous material and a typical representative of the M41S group. At the nanoscale, MCM-41 exhibits an ordered "honeycomb like" porous structure, which is an array of one-dimensional linear channels with hexagonal dense clusters. Its pore size can be continuously adjusted in the range of 2-10nm, with the most typical pore size being 4nm. During electron microscopy observation, it was found that the pores could penetrate the entire molecular sieve.
2. Applicaiton
MCM-41 molecular sieve, as a highly ordered mesoporous material, has a large and uniform pore size, a large specific surface area, a large adsorption capacity, and high thermal stability (over 900 ℃). The morphology of MCM-41 particles exhibits various peculiar geometric shapes, such as hexagonal shape, spherical shape, solid fiber sphere, hollow tube shape, iron cake shape, wheel shape, etc., making it suitable for loading organic ligands and transition metals under harsh reaction conditions. This mesoporous material has not only received considerable attention in adsorption, drug transport systems, extraction, and catalytic applications, but can also be regarded as a good hydrogen storage medium. It is also widely used in the fields of catalysis and petrochemicals, such as residue catalytic cracking, heavy oil hydrogenation, lubricant hydrogenation, alkylation, olefin polymerization, and separation of CO2 and CH4 in acid catalysis. In addition, MCM-41 molecular sieve also has high application value in environmental applications, multiphase catalysis, ion exchange, guest chemistry, sensing technology, and optoelectronic devices. Sieve particles with a pore wall thickness generally around 1nm.
