Abstract

The invention relates to a piece of novel graphene-like molybdenum disulfide-based self-cleaning ecological glass and a preparation method thereof. A molybdenum disulfide material is directly grown onthe common glass surface by chemical vapor deposition (CVD), and the composition of the material is MoS2, and a molybdenum disulfide film has a photocatalytic degradation function to achieve the self-cleaning purpose. In the growth process of the material on the glass surface, the surface morphology of the growth direction of molybdenum disulfide is controlled by changing the vulcanization temperature to improve the photocatalytic degradation capability of organic matters. Moreover, the molybdenum disulfide is directly grown on the glass and is more stable than the film formed by the 'transfer technique'. After eight cycles, no loss of activity or shedding occurs, and the stability is still strong. The preparation of the novel graphene-like molybdenum disulfide self-cleaning glass furtherpromotes development and application of the self-cleaning glass preparation technology.

Description

technical field [0001] The invention belongs to the field of functional materials and glass processing, and relates to a novel graphene-like molybdenum disulfide-based self-cleaning ecological glass and a preparation method thereof. Background technique [0002] Self-cleaning glass is an eco-friendly "green glass" with self-cleaning function. It has the functions of cleaning, sterilizing and mildew-proof, removing formaldehyde, deodorizing, deodorizing, surrounding air and environmental purification, and can be widely used in various Building materials, glass curtain walls and other living glass products. Self-cleaning glass forms a photocatalytic film of nano-scale particles and nano-scale microporous structure on the glass surface, uses sunlight to generate photocatalytic reaction, and decomposes the pollution adsorbed on the glass surface due to external environmental pollution to achieve self-cleaning effect. At present, the research focus of self-cleaning glass is main...
