Titanium carbide sheet layer/molybdenum sulfide nanosheet/titanium dioxide nanosheet composite and preparing method thereof

Abstract

The invention relates to a titanium carbide sheet layer / molybdenum sulfide nanosheet / titanium dioxide nanosheet composite and a preparing method thereof. The method includes the steps of conducting the mixing reaction on titanium aluminum carbon and hydrofluoric acid, conducting the hydrothermal reaction on an obtained precipitate A, adding a molybdate thiopolybdate solution to a precipitate C obtained through the hydrothermal reaction, and conducting the photo-reduction reaction to obtain the titanium carbide sheet layer / molybdenum sulfide nanosheet / titanium dioxide nanosheet composite. The composite is applied as a photocatalyst in water photocatalytic decomposition. The composite is an efficient photodecomposition water catalyst with a precious-metal-free double-aid catalyst, and the photocatalysis effect is remarkably improved.

Description

technical field

[0001] The invention belongs to the technical field of catalyst material preparation, and in particular relates to a titanium carbide sheet / molybdenum sulfide nanosheet / titanium dioxide nanosheet composite material and a preparation method thereof. Background technique

[0002] With the rapid consumption of global fossil energy and the deterioration of the environment, the development of environmentally friendly, low-cost, and resource-rich renewable energy has become an urgent problem facing mankind. As an environmentally friendly energy source, hydrogen has a high calorific value, is easy to transport, and is renewable. Therefore, converting solar energy into hydrogen energy is one of the most ideal ways to develop new energy sources. Hydrogen production by photolysis of water can directly use solar energy to decompose water to produce hydrogen, does not consume other energy sources, and has no pollution to the environment. It has attracted extensive attent...
