The catalyst is added to a small amount of material in the catalyst, the catalyst is the auxiliary components, which itself has no activity or activity is very small, but they added to the catalyst, can change the chemical composition of the catalysts, chemical structure, ion valence, pH, lattice structure, surface structure, pore structure, dispersion state, the mechanical strength, so as to improve the catalyst activity, selectivity, stability and life.
