Explanation

It is abbreviated as catalysis. The general term for the role and related phenomena of catalysts in chemical reactions. Catalyst refers to the substance that can increase the reaction rate and speed up the process of reaching chemical equilibrium, but does not consume itself at the end of the reaction. In the catalytic reaction, the catalyst and reactants react chemically, changing the reaction path, thus reducing the activation or conditioning energy of the reaction. There are two types of catalysis, homogeneous and heterogeneous. The former is that the catalyst and reactant are in the same phase, such as the catalysis of organometallic compounds in solution; The latter refers to the catalysis in which the catalyst and reactants are in different phases, such as the gas-phase or liquid-phase reactants and solid catalysts form the gas-phase or liquid-solid interface.
