Abstract

The invention relates to a hydro-thermal synthesis method for a molybdenum-sulphur co-doped mesoporous nano titanium dioxide visible-light-driven photocatalyst. The method comprises the following steps: preparing an ethylene glycol titaniumprecursor by adopting a known technical method in prior art, mixing the precursor, sodium molybdate, thiourea and water according to a certain ratio to prepare a solution, and implementing a simple hydro-thermal synthesis method to obtain the molybdenum-sulphur co-doped mesoporous nano titanium dioxide visible-light-driven photocatalyst. Shown from an XRD spectrogram, the prepared molybdenum-sulphur co-doped mesoporous nano titanium dioxide visible-light-driven photocatalyst is in a typical anatase structure and has the good crystallinity. The co-doping of molybdenum and sulphur can be proved by the XRD spectrogram. Visible-light-driven photocatalyzing results show that the molybdenum-sulphur co-doped mesoporous nano titanium dioxide visible-light-driven photocatalyst prepared by adopting the method disclosed by the invention has an excellent visible-light-driven photocatalyzing performance, can be used for effectively solving problems of environment pollution and the like, and has potential application prospects in fields of energy and the like.

Description

technical field

[0001] The invention relates to a preparation method of titanium dioxide nanometer material, in particular to a hydrothermal synthesis method of molybdenum and sulfur co-doped mesoporous titanium dioxide nanometer visible light catalyst. Background technique

[0002] Photocatalytic technology is an environmentally friendly catalytic technology. Due to its clean energy utilization, low energy consumption, mild reaction conditions, no secondary pollution, and easy operation, it has become a research hotspot in the field of environmental governance and energy regeneration. Titanium dioxide, one of the most famous and widely used photocatalysts, has many excellent properties as a photocatalyst, such as: high photoelectric conversion efficiency, chemical stability and non-toxic and harmless. However, only ultraviolet light can excite titanium dioxide to produce interband electronic transitions, so a lot of work and measures are trying to further expand its light-a...
