Guide you to a detailed understanding of platinum catalysts
Platinum catalyst is a general term for catalysts made with platinum metal as the main active component. Platinum metal mesh, platinum black, or platinum supported on alumina or other carriers can also contain metal rhenium as a co catalyst component. Mainly used for processes such as ammonia oxida

The influence of catalyst pore structure on catalytic reactions
In the production of chemical industry, the reactant molecules participating in catalytic reactions need to be dispersed through the pores to reach the interior of the catalyst, so the pore structure will be affected by internal diffusion to varying degrees. The diffusion of reactant molecules withi
