INTRODUCTION

The organization of the microporous region in zeolites is examined. A sodalite cage, a supercage, a tertiary building unit, a primary building unit, and secondary building units-or building polyhedral are the components of a new step-by-step model that explains the principles of organizing the hierarchy of microporous space at the stage of assembling zeolites from components of minimal size. Zeolites with both small and large micropores of sodalite (SOD), zeolites of types A (LTA), X, and Y (FAU), and type BETA (the largest diameter of a sphere that can enter the pores is 0.67 nm) have been chosen as the model materials.

We think this approach will be helpful in developing strategies to produce complex zeolite compositions for particular applications like catalysis, where computer modelling can play a significant predictive role and the size of the molecules entering the voids is determined by the geometry of the pores. This work examines specific aspects of using the heat desorption method to study mesoporous materials using a BETA zeolite as an example. The results of experimental research into the properties of the porous structure of hierarchically structured zeolite materials (specific surface area 180-380 m²/g, external surface area 120-200 m²/g, and micropore volume 0.001 mL/g-0.1 mL/g) are presented.

Description

Materials science has advanced quickly in recent years. The concept that point defects within a homogenous area may be regulated to define the material properties was the foundation of materials physics and chemistry in the past hardness, charge carrier concentration in semiconductors, etc. The statement “From classical thermodynamics, where it was necessary to set the temperature and obtain the material, to ensure additional conditions, in particular the component pressures of one of the elements (if it is a binary compound), to stabilize the number of point defects in the crystal structure,” was regarded as a generalization in the field of materials science. When materials science began studying nanoparticles, this formula got more difficult because the properties of materials also depend on the size and shape of the nano-object.

After the absorption procedure is finished, the ampule containing the sample is taken out of the cryogenic storage and heated to about 100 K. (the upper red line). The desorption process starts at the same time as a more distinct desorption spike, represented by the blue line. All ensuing calculations are made using the graph’s size below the desorption curve as a starting point. The black dashed line shows variations in the adsorbent gas pressure when the pressure is set before each cycle of measurement. Despite a number of disadvantages, such as the requirement of employing models, the mistakes included in the BET approach, and the labor- intensive nature, the TDM is a unique method that is capable of studying very small pores (referred to as micropores).

Conclusion

The production of new items by materials scientists with novel properties, particularly in the context of atomic and molecular design and nanoarchitecture. Creating cross-disciplinary linkages between topics like “Nanomaterial science,” “Nanotechnology,” and “Descriptive geometry, engineering, and computer graphics” in order to improve students’ ability to depict space and think geometrically. Building zeolite structures and models through the use of geometrical simulation can actively promote the idea of cross-disciplinary interaction, which is in many ways the cornerstone of contemporary educational standards and is in line with the strategic directions of contemporary scientific research.
