Compared with the traditional technology, the energy source of the photocatalysis technology is solar energy, and the photocatalysis technology is clean and almost infinite energy. The photocatalysis technology is used for treating organic pollutants in water or air, and is probably one of the technologies suitable for treating the future environmental pollution.
Research on photocatalytic degradation of organic pollutants in water has been developed for decades, and many types of photocatalysts effective in organic matter degradation are reported, wherein a titanium dioxide photocatalyst has the obvious advantages of low price, large storage capacity, simple preparation method, no toxicity and the like, but has the defects of only absorbing ultraviolet light, fast recombination of photogenerated electron holes and the like. In the current research, most of the catalysts used in the degradation process are fine powder particles, and after the degradation is finished, the catalysts need to be separated from the reaction liquid by using a centrifugal or filtering method, but in the actual operation, the centrifugal separation method is long in time consumption and high in energy consumption. Fine catalyst particles easily block the filter during filtration, so that the separation effect is poor, and the industrial application prospects of the two methods are not good.
How to prepare the catalyst with higher activity and can effectively and simply separate the catalyst and the treated liquid with low energy consumption when degrading organic pollutants, and the catalyst can be reused, and the treated liquid can meet the discharge requirements of environmental protection departments and can even be recycled is the problem which needs to be researched and solved at present.

The invention provides a Ti3C2@TiO2The photo-thermal catalyst, the preparation method thereof and the method for degrading organic pollutants have the beneficial effects that:
in the preparation of Ti3C2@TiO2When the photo-thermal catalyst is used, the photo-absorption capacity of the photo-thermal catalyst is increased through a nano technology, photo-generated electrons and holes of the photo-thermal catalyst are quickly separated, the recombination probability is reduced, and the photo-catalytic efficiency is greatly improved. Secondly, when organic pollutants are degraded, through a photo-thermal conversion technology, water molecules after degradation are evaporated and separated by solar energy while the organic pollutants are subjected to photocatalytic reaction, so that the catalyst and the treated liquid do not need to be additionally separated, and the catalyst can be repeatedly used and still can keep catalytic activity.
