How does the use of pseudo-boehmite as a catalyst produce a chemical reaction?

When pseudo-boehmite co-catalysts are a small amount of substances added to the catalyst and are auxiliary components of the catalyst, they have no activity or little activity, but after they are added to the catalyst, they can change the chemical composition, chemical structure, Ion valence state, lattice structure, surface structure, pore structure, dispersion state, mechanical strength, etc., thereby improving the activity, selectivity, stability and life of the catalyst

Catalytic reactions have four basic characteristics:

(1) Catalysts can only accelerate reactions that can be carried out thermodynamically. When asked to develop a catalyst for a new chemical reaction, the first step is to perform a thermodynamic analysis of the reaction to see if it is a thermodynamically feasible reaction.

(2) The catalyst can only accelerate the reaction to equilibrium, and cannot change the equilibrium position of the reaction.

(3) The catalyst has selectivity for the reaction. When the reaction may have more than one different direction, pseudo-boehmite as a catalyst only accelerates one of them, and the reaction rate and selectivity are unified.

(4) The life of the catalyst. A catalyst can change the rate of a chemical reaction without itself entering the reaction, and ideally the catalyst is not changed by the reaction. However, in the actual reaction process, some irreversible physical and chemical changes will also occur when the catalyst is heated and chemically acted for a long time.

Summary: Pseudo-boehmite is used as a catalyst to react in chemical rate and change physical properties, it changes the way of the reaction, so that pseudo-boehmite is added as a catalyst and acts as a catalyst carrier.
