The application of quasicrystals to a catalyst is one of the most important and promising methods for improving the catalytic activity and selectivity of various catalysts. Quasicrystals are materials with an aperiodically ordered structure that has a number of unique physical and chemical properties.
The use of quasicrystals as nanocatalytic materials opens up new opportunities for rational control of the mechanisms of chemical reactions. Certain chemical properties of quasicrystals make it possible to effectively control the activity of the catalyst, increasing its efficiency and selectivity when performing various chemical transformations.
One of the main methods for depositing quasicrystals on a catalyst is the method of physical deposition from the gas phase. In this process, the use of suitable reagents and optimal deposition modes makes it possible to obtain a uniform and stable coating of the catalyst surface with quasicrystals. This coating helps to increase the active surface of the catalyst and improve the reaction kinetics.
Quasicrystalline coatings obtained on various types of catalysts demonstrate high catalytic activity and stability in many chemical reactions. This opens up new prospects for their use in industry, especially in catalysts for organic synthesis processes and the neutralization of harmful emissions.
Despite significant advances in the field of deposition of quasicrystals on catalysts, many aspects of this process remain the subject of active research. Optimization of reaction conditions, design of new synthesis gas mixtures and development of new catalysts with increased stability and selectivity are important areas for further research.
Thus, the deposition of quasicrystals on catalysts is a significant method for improving the catalytic activity of various types of catalysts. Further research in this area will contribute to the development of new effective technologies in the field of catalytic chemistry and industry.
