Significance

Multilayer b-orientated HZSM-5 catalytic coating is controllably synthesized by repeated growth of zeolite layer on Ti[BOND]OH-modified surface of sublayer. The as-prepared zeolite coating shows performance enhancement up to 110% in catalytic cracking of n-dodecane ascribed to enhanced mass transfer in its straight and short pathway along the b-axis. © 2014 American Institute of Chemical Engineers AIChE J, 60: 1964–1968, 2014
