摘要
Advantageous doping: Theoretical calculations reveal that the amine-doped H-ZSM-5 zeolite is intrinsically more activated than the full oxygen H-ZSM-5 zeolite for the ethene protonation reaction, which is evidenced by the considerable decrease of activation barrier and the remarkable acceleration of reaction rate for the acid-base bifunctional reaction.
