Abstract

The invention discloses a preparation method of mesoporous SO4<2-> / ZrO2. According to the preparation method, in-suit introduction of a sulfur-containing compound into a synthesis system of a zirconium-based MOFs material is carried out, and the sulfur-containing zirconium-based MOFs material is roasted in an oxygen-containing atmosphere at a certain temperature to prepare mesoporous SO4<2-> / ZrO2. The preparation method is simple and convenient; the prepared mesoporous SO4<2-> / ZrO2 possesses a uniform mesoporous structure, large specific surface, and specific morphology characteristics; and stability of loaded sulfur obtained via the preparation method is high, leaching is not easily caused, and the preparation method is an effective method used for preparing mesoporous SO4<2-> / ZrO2.

Description

technical field

[0001] The present invention relates to mesoporous SO 4 2- / ZrO 2 The preparation method, especially involving the introduction of sulfur-containing compounds in the synthesis system of zirconium-based MOFs materials, and the preparation of mesoporous SO with sulfur-containing zirconium-based MOFs materials 4 2- / ZrO 2 Methods. Background technique

[0002] SO 4 2- / ZrO 2 It is a potential heterogeneous solid acid catalyst, because of its high acid strength and the synergistic effect of acid centers (Bronsted acid and Lewis acid), it can be used in esterification reaction, etherification reaction, hydration-dehydration reaction, cracking reaction and hydrocracking and other chemical reactions [B. M. Reddy and M. K. Patil, Chem. Rev., 2009, 109, 2185–2208; G. D. Yadav and J. J. Nair, Micropor. Mesopor. Mater., 1999, 33 , 1-48].

[0003] SO 4 2- / ZrO 2 The preparation of ZrO usually adopts the following method: first, the precipitation method is us...
