Molecular sieve manufacturer explains the structural chemistry of zeolite molecular sieve

Zeolite molecular sieve is a three-dimensional framework structure formed by silica tetrahedron and alumina tetrahedron. It has a complex structure formed by a sufficiently large pore size and cage structure, which can allow some super large cations and molecules with size less than 1 nm to adsorb and desorb on the surface. Their physical and chemical properties are directly determined by the structure of molecular sieves, so molecular sieves have a lot of applications in the field of ion exchange, separation and catalysis. Today, molecular sieve manufacturers will explain the structural chemistry of zeolite molecular sieve.
Zeolite molecular sieves originated from silica-aluminum minerals. Zeolite molecular sieves can be used to meet different catalytic effects by adjusting different components. Hunan Tianyi New Material Co., Ltd. is a molecular sieve manufacturer specializing in the production of NaY molecular sieve, Y-type molecular sieve, ZSM-5 molecular sieve, USY molecular sieve, REY molecular sieve and other main products.
In the past 20 years, scientists in the world have made a lot of efforts in the field of synthesis of molecular sieves with new structure (mainly used for adsorbents and catalysts). People have focused on the exploration of using complex alkyl cations as synthesis templates, and have obtained some molecular sieves with high or pure silicon. In addition to silicon and aluminum, the introduction of other heteroatoms increases the number of molecular sieves with new structures. In addition, a large number of false molecular sieve structures may exist, which has prompted more and more people to focus on the research of new structural materials. The appearance of some landmark molecular sieves with new structure makes people realize that the structural characteristics of new molecular sieves are still very novel and have potential important value: the increasingly complex crystal morphology makes the new molecular sieves combine in pore size, size and connection mode; The combination of different skeleton elements with four coordination; Chiral and mesoporous combination; Synthesis of ordered defect samples; Synthesis of layered precursor samples.
From 1993, when the structure of the natural mineral sodalite was first clarified, to today, natural ores have given zeolite chemists a lot of inspiration. At present, many commercially important zeolites can be regarded as mineral zeolites. These zeolites have been synthesized in the laboratory, and these materials are very suitable for single crystal diffraction. For the scientists of zeolite synthesis, they hope to observe the molecular sieves with mineral zeolite structure, which can show that their combination should be feasible. Hunan Providence New Materials Co., Ltd is a professional molecular sieve manufacturer which can provide USY zeolite, NaY zeolite, REY zeolite, ZSM-5 zeolite, welcome to consult.
