Under the background of environmental protection, there are opportunities for the development of nanocatalyst industry

Nanocatalyst refers to a catalyst whose active component particle size is less than 100.0nm. As the particle size of nanoparticles gradually shrinks, their surface smoothness will become worse, and the contact surface for chemical reactions will increase significantly, making them the basic conditions for acting as a catalyst.

There are many types of nanocatalysts, including five categories: nanosolid superacid catalysts, nanosemiconductor particle photocatalysts, nanometal particle catalysts, nanoimmobilized heteropolyacid catalysts, and nanometal oxide catalysts. Among them, nanosemiconductor particle photocatalysts are nanocatalysts. The most widely used segmented products. Titanium dioxide and zinc oxide have the advantages of corrosion resistance and light radiation resistance, and are highly practical nano-semiconductor particle photocatalyst raw materials. At present, titanium dioxide nanocatalysts have been widely used in sewage treatment, exhaust gas treatment and other fields.

Nanocatalyst preparation methods include microwave synthesis, hydrolysis, sol-gel, ion exchange, inert gas evaporation, impregnation, etc. The microwave synthesis method is mainly used to prepare nano-semiconductor particle photocatalysts. It uses urea as the nitrogen source and water as the solvent. The original solution is decomposed under the action of microwave radiation to generate highly active nano-catalysts. The use of microwave synthesis method can accurately control the particle size and particle size distribution of nanoparticles and improve the reaction speed of the product. It is the best method for preparing nanocatalysts.

Nanocatalysts have a wide range of applications, including environmental protection, power supply, petrochemical industry, etc. In the field of environmental protection, nanocatalysts can effectively decompose indoor and outdoor organic pollutants, including various types of odors and sulfides, and have the advantages of low operating costs and low secondary pollution. In the field of power supply, nanocatalysts can be used as battery electrodes, which have the advantages of improving battery efficiency and reducing weight.

According to the “2022-2027 China Nanocatalyst Industry Market In-depth Research and Development Prospects Forecast Report released by Synopsys Industrial Research Center , At present, my country’s nanocatalyst industry is still in its infancy, and stability issues have become an important bottleneck in its industrialization. Production companies and research institutions such as the Academy of Petroleum and Chemical Engineering, the Institute of Chemistry of the Chinese Academy of Sciences, PetroChina, Sinopec, Shenhua Group, and Shanxi Coal Chemical Institute have begun research on nanocatalyst technology. In 2021, Professor Li Weixue’s team at the University of Science and Technology of China established a general theory of nanocatalyst growth kinetics, which will lay a scientific foundation for the development of my country’s nanocatalyst industry.

Industry analysts said that driven by the “double carbon” goal, nanocatalysts can be used to solve environmental problems and achieve efficient chemical production and other chemical industries. products will have broad development prospects. At present, my country’s nanocatalysts are still in their infancy, and there are still many bottlenecks in industry development. However, driven by the rapid development of nanoscience and technology, nanocatalysts are expected to be widely used in the industrial field, which will bring opportunities for industry development.
