Abstract:Constructing zeolite catalysts with excellent mass transfer and active site accessibility is the key to improving their catalytic efficiencies. Herein, a zeolite subcrystal catalyst with high short-range ordering but X-ray amorphism is prepared to minimize the existing molecular mass-transfer barrier of conventional zeolite catalysts. Various characterizations confirm its size of smaller than 10 nm, definite MFI framework, complete opened micropore channel, and abundant accessible acid sites. Moreover, physica… Show more
