Abstract

The invention belongs to the technical field of aerogel preparation. It discloses a preparation method of three-dimensional graphene / molybdenum disulfide aerogel doped with ethyl orthosilicate. It breaks through the traditional method of obtaining aerogel by freeze-drying and innovatively Introducing ethyl orthosilicate and realizing the preparation of three-dimensional graphene / molybdenum disulfide aerogel through silicide filling, the best stable preparation process is established; no chemical cross-linking agent is needed, it is simple and highly controllable; it is easy to use Ray diffraction, infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and Raman spectroscopic detection and analysis showed that the prepared 3D‑MoS 2 / G sample has the characteristics of low density, high porosity, high mechanical strength and high stability. Compared with other existing methods, this preparation process has better stability and repeatability, and can provide reference for the construction of other metal sulfide and graphene assembly composites and their application research.

Description

technical field [0001] The invention belongs to the technical field of airgel preparation, and in particular relates to a method for preparing a three-dimensional graphene / molybdenum disulfide airgel doped with ethyl orthosilicate. Background technique [0002] Coal gasification technology is playing an increasingly important role in industrial production, and the desulfurization link to improve the production efficiency of this technology is a key component of the system. Carbon-based materials have excellent stability and adsorption properties, and have been widely used as support materials in the preparation of supported noble metal catalysts. So after a lot of research, it was found that MoS 2 Composite materials combined with graphene exhibit superior electrocatalytic activity compared with traditional noble metal catalysts. The three-dimensional graphene assembly can often repair the conjugated structure of the carbon crystal plane during the formation process, and t...
