Abstract

The invention discloses a preparation method and application of a copper sulphide / molybdenum sulfide composite. According to the preparation method, raw materials, namely (NH4)6Mo7O24.4H2O, Cu(CH3COO)2 and 1,3-di(thioacetic acid-S-n-propyl)imidazolium bromide are subjected to one-pot synthesis by a hydrothermal process to obtain the copper sulphide / molybdenum sulfide composite; preparation condition of the composite is evaluated according to the catalytic hydrogenation effect to naphthalene, and reaction temperature and time and proportion of raw materials in preparation of the composite are optimized; particularly, on the optimized reaction conditions that the mass ratio of Mo, Cu to S of (NH4)6Mo7O24.4H2O, Cu(CH3COO)2 and 1,3-di(thioacetic acid-S-n-propyl)imidazolium bromide is 1:1: 2.5,the reaction temperature is 160 DEG C and the reaction time is 8 hours, the catalytic hydrogenation conversion rate of the copper sulphide / molybdenum sulfide composite prepared by the method to naphthalene is up to 55.6%. In the reaction process, 1,3-di(thioacetic acid-S-n-propyl)imidazolium bromide functional ionic liquid can serve as not only a sulfur source but a surfactant, and thus use of raw materials and cost are both reduced.

Description

technical field

[0001] The invention relates to the technical field of preparation methods of two-dimensional molybdenum disulfide, in particular to a preparation method and application of a copper sulfide / molybdenum sulfide composite material. Background technique

[0002] With the research and development of various nanomaterials, the preparation and application of molybdenum disulfide nanomaterials have gradually entered the field of vision of scientists. In 1995, Israeli scientist R. Tenne et al. synthesized molybdenum disulfide nanomaterials with fullerene structure for the first time. After particles and nanotubes, nanorods, nanoflowers, nanowires and nanosheets of molybdenum disulfide have gradually become the research hotspots in the scientific community; in the early stage of research on molybdenum disulfide nanomaterials, due to the good friction Therefore, the material has been developed into various excellent lubricants and is widely used in the industrial field;...
