Synthesis of b-oriented TS-1 zeolite membranes with high performance in the oxyfunctionalization of n-hexane

The b-oriented TS-1 zeolite membranes were synthesized with higher reproducibility by a simple secondary growth method, in which the membranes grew from b-oriented seed layers obtained by ultrasonication–electrostatic adsorption. The membranes demonstrated excellent catalytic performance in the oxyfunctionalization of n-hexane with a high average reaction rate of 1423 mol m− 3 h− 1.
