Abstract

The invention discloses a method for synthesizing mesoporous molybdenum disulphide by taking a mesoporous silica molecular sieve as a hard template. The method comprises the following steps of: firstly, preparing a hydrochloric acid solution of alcohol amine; secondly, adding ammonium tetrathiomolybdate, standing at room temperature after stirred reaction, filtering, cleaning and drying in vacuumto obtain a precursor; thirdly, dissolving the precursor into water and absolute methanol, adding the mesoporous silica molecular sieve, and carrying out ultrasonography after stirred reaction to obtain a solid and liquid mixture; fourthly, placing the solid and liquid mixture into a muffle furnace after filtering, cleaning and drying, raising the temperature to 400-450 DEG C under the protectionof hydrogen, then, preserving the temperature for 1-2h, and cooling to the room temperature to obtain mesoporous molybdenum disulphide powder containing the mesoporous silica molecular sieve; and fifthly, cleaning 1-5 times by using an HF (Hydrogen Fluoride) aqueous solution and drying to obtain the mesoporous molybdenum disulphide. The mesoporous molybdenum disulphide synthesized by using the method provided by the invention is high in catalytic activity, the yield of tar obtained in coal pyrolysis reaction is high, and the using amount of catalysts is small, and no assistant is needed.

Description

technical field

[0001] The invention belongs to the technical field of inorganic porous materials, and in particular relates to a method for synthesizing mesoporous molybdenum disulfide by using mesoporous silica molecular sieve as a hard template. Background technique

[0002] Compared with the increasingly scarce petroleum resources and the scarce natural gas resources, coal is not only the main energy resource in my country, but also the source of many important chemical raw materials and chemicals. At present, the utilization efficiency of coal in my country is very low. Therefore, how to comprehensively utilize coal resources more reasonably, efficiently and cleanly is not only a major concern of the country, but also of the majority of scientific researchers and related enterprises.

[0003] Through coal pyrolysis, the composition and structural characteristics of coal are used to prepare high value-added chemicals and substitute oil and gas products, and the directio...
