Nanosheet HZSM‐5 film vertically grown on the substrate with the tailorable macro‐ and meso‐pores between the layers of nanosheets is hydrothermally synthesized by seed‐assisted secondary growth method. The as‐prepared nanosheet HZSM‐5 film exhibits reaction rate enhancement up to 312% in catalytic cracking of n‐dodecane as well as twice light olefins selectivity, ascribed to the better mass transfer of reactants in the hierarchical porous structure and the ultra‐thin b‐axis pores of nanosheets. © 2018 American Institute of Chemical Engineers AIChE J, 64: 1923–1927, 2018

垂直二次生长可控制的纳米片HZSM-5薄膜的制备和催化性能

通过种子辅助二次生长法水热合成在基材上垂直生长的纳米片材HZSM-5薄膜，纳米片层之间具有可定制的大孔和中孔。制备的纳米片HZSM-5膜在正十二烷的催化裂化中显示出高达312％的反应速率，并且轻烯烃的选择性提高了两倍，这归因于反应物在分级多孔结构中的更好的质量转移和超薄纳米片的b轴孔。©2018美国化学工程师学会AIChE J，64：1923–1927，2018
