Many people have a very limited understanding of organic germanium, but today we first put down this and three (dimethylaminopropyl) amines, organic germanium, test long tail words, and the like, and let us take a look at the catalytic role of catalysts. How to classify what is the working principle of the catalyst", I hope you have more understanding

Catalytic effect can be divided into the following types: 1 homogeneous catalysis. Both the catalyst and the resonator are in the same phase of catalytic effect, such as homogeneous acid-base catalysis, homogeneous complexation catalysis, and the like. Homogeneous catalysis is mostly carried out in the liquid phase. The homogenous catalysts have relatively homogeneous active centers, high selectivity, and few side reactions, but the catalysts are difficult to separate, recover, and regenerate.

2 Heterogeneous catalysis. Onset of catalytic effect at the two-phase interface. In general, the catalyst is a porous solid, and the reaction substance is liquid or gas. In the heterogeneous catalysis response, the solid catalyst has a chemisorption effect on the reactivator molecules, activates the reactivator molecules, lowers the activation energy of the reverberation, and accelerates the reverberation rate. The appearance of the solid catalyst is non-uniform, as long as part of the point chemisorption of the reverberant molecules is called the active center. Most of the catalytic effects in industrial production are attributed to heterogeneous catalysis.

3 Biocatalysis. The catalysis response under the effect of living body enzymes. The catalytic effect of the enzyme has the characteristics of high selectivity, high catalytic activity, mild reaction conditions and other characteristics, but is affected by temperature, pH value in the solution, ionic strength and other factors.

4 active catalysis. Reactive products' self-catalytic effect. In some reactions, some of the products or intermediates that are affected have catalytic catalytic catalysis. The categorization of how the catalysis of the catalyst is catalyzed will greatly accelerate the response after a period of induction. The autocatalytic effect is one of the necessary conditions for the onset of chemical vibration.
