Note: One of the catalytic systems is nanoreactors. One of the applications of nanoreactors is in the electronic conduction of porous materials whose dimensions are smaller than 0.11 nanometers.
Nanoreactors are very diverse. Simple or complex, organic and inorganic materials with electrical conductivity, volume and pore structures are used as nanoreactors. Unlike microreactors, the reaction space inside nanoreactors greatly affects the mobility and interactions between molecules inside it. Therefore, a nanoreactor is not just a simple storage container and plays an important role in the electrochemical process. Nanoreactors are relatively new materials, but in nature, various processes have long been using nanoreactors. Carrying out electrochemical reactions in confined spaces with nanometer dimensions and micrometer volumes leads to changes in the kinetics and path of the entire process. Such confined spaces used to carry out specific electrochemical reactions are called nanoreactors . Nanoreactors are very small containers with nanometer dimensions that have great potential for improving electrochemical conversions by protecting catalysts from environmental effects and confining reactants and catalysts in a small space for a long time . In fact, nanoreactors are porous materials with one of their dimensions being on the nanoscale.

The countless and simultaneous reactions in the cells of living organisms are also based on this principle. Therefore, various biological and chemical structures that have the characteristics of a nanoreactor are used. Reason and advantages of using a reactor and nanoreactors On a macroscopic scale, a chemical reactor is a chamber that allows the reaction to take place in a specific volume. One of the advantages of using a reactor is the ability to precisely control the reaction conditions such as solvent, temperature, and stirring speed. On a micro and nano scale, chambers can also be created that separate a specific volume of the reaction mixture from the bulk medium . If a chemical reaction is confined within such a chamber, then this chamber is considered a nanoreactor. The advantages of using nanoreactors include greater control over the reaction, selectivity, separation of porous materials, and electronic conductivity of nanomaterials from the bulk medium, followed by a reduction in system toxicity or an increase in catalyst stability, and their ideality in electrochemical processes due to their small size.

Conclusion :
In general, nanostructured materials with specific size, shape, and geometry have unique and different properties from bulk materials. By using reaction environments with nanometer and micrometer dimensions, they can produce new nanomaterials with interesting and remarkable properties. In general, nanoreactors are containers with nanometer dimensions in which chemical reactions can be carried out. Of course, nanoreactors are also considered part of the reaction in some way, and this is their main difference from microreactors. One of the useful solutions for achieving the nanoreactor environment is the use of porous materials, so due to the importance of the subject of nanoreactors, porous silicate and zeolite structures are among the most prominent and widely used compounds in this group .
