What is the active ingredient in melamine catalysts?

May I ask: What is the active ingredient in melamine catalysts?
It’s not entirely clear whether it’s Y–Al2O3
Many catalysts contain aluminum oxide, but it generally serves as a carrier. The active ingredient in melamine can’t be aluminum oxide, right?
The most ideal catalyst for melamine at present is coarse-pore microspherical silica gel; therefore, silicon and resin, as well as silica, should be the main components
It also contains SiO2 and Fe2O3; I’m not sure if that’s the case.
They are silica or silicoalumina particles; silica is pure white, while silicoalumina is slightly yellowish.
For silica gel catalysts, their main component is SiO2.
It should be silicon and resin, silica I guess
Based on the explanations provided by the experts in the conference hall, is silica the active component of melamine catalysts?
The catalysts for melamine include (all of which can be used in the same apparatus, depending on the company’s preferences and operational practices*): coarse-pored silica gel (the most commonly used), silicoalumina gel, and alumina
I would like to ask an expert: Among the three catalysts you mentioned, is the coarse-pored silica gel, which is the most widely used, the main trend for future development? What are its main advantages?
