Preparation and Catalytic Properties of Zn-HMS Molecular Sieves

Abstract:

Znic-containing mesoporous HMS (Zn-HMS) with various znic contents were synthesized by using netural dodecylamine(DDA) as template at ambient temperature and characterized by means of XRD, FT-IR and TEM. The catalytic performance of Zn-HMS was evaluated by the oxidation of thiophene, and the influences of the zinc content and zinc source on the catalytic performances of the samples were studied. It was observed that a limited content of zinc can be incorporated into the siliciate framework of HMS and appropriate amount of zinc incorporated would promote the formation of the typical wormhole-like structure of HMS and exhibited high catalytic properties while excessive zinc incorporated would destroy the structure. Besides, for all the zinc sources, the samples synthesized from Zn(NO3) 2 have better catalytic effect, and it is benefical for zinc incorporating.
