Titanium dioxide will replace the broad application of graphene

China University of Science and Technology revealed the catalytic activity and microscopic reaction mechanism of titanium dioxide (commonly known as "titanium dioxide") in an anatase structure, which is expected to be applied to the preparation of organic solar cells and the conversion of solar energy into environmentally friendly chemical energy. The use of titanium dioxide for high-end applications is not alone. Overseas media even pointed out that: multi-purpose titanium dioxide will replace the wide range of graphene applications, becoming the "world's most useful material."

An agency official told the Shanghai Daily that the traditional downstream of titanium dioxide, such as coatings, textiles, and paper, will hardly see rapid growth in the medium term, but the use of new materials in the fields of environmental protection, new energy, high-end equipment, and medical applications will become the cause of titanium dioxide. Traditionally, there is a short cut to high-end transformation.

Breakthroughs in the use of titanium dioxide in the near future, in new energy, environmental protection, high-end equipment, medical and other new material breakthroughs in almost all areas, can find the figure of titanium dioxide. According to people from domestic institutions, the so-called excess capacity is only a bottleneck in the development of traditional fields. Once breakthroughs are made in new technologies and new materials, the future development of titanium dioxide is limitless.

The latest research results of the China University of Science and Technology team have incorporated titanium dioxide into the new energy development map. The scientific team of the University of Science and Technology recently pointed out in the paper that titanium dioxide, as an oxide semiconductor, is an important material system in the research of solar energy conversion. It is expected to be applied in the preparation of organic solar cells, conversion of solar energy into environmentally friendly chemical energy, and bright prospects for the photocatalytic decomposition of water to hydrogen and artificial photosynthesis.

A few days ago in the research of the Australian National University supercapacitor, titanium dioxide plays the leading role again. In the process of manufacturing supercapacitors, Australia discovered a kind of insulating material that can store more electric energy and consume less loss: rutile (titanium dioxide) with a bismuth-indium composite coating. Rutile is a relatively pure titanium dioxide, but also the best raw material for the production of rutile titanium dioxide.

In the field of environmental protection, titanium dioxide is transformed into a versatile flexible filter membrane. It is understood that this versatile flexible filter film can be used to improve battery life, purify water, and manufacture antimicrobial medical materials. The use of titanium dioxide in the field of environmental protection has also extended to the prevention of air pollution. In the Netherlands, scientists are studying the mixing of titanium dioxide with asphalt or concrete to eliminate 25% to 45% of nitrogen oxides in vehicle emissions and reduce pollutants in the air.

The study of titanium dioxide to convert nanomaterials has reached the stage of setting standards. Two international standard new projects led by China Academy of Inspection and Quarantine, ISO/TS11931 "characterization and measurement of nano calcium carbonate part 1" and ISO/TS11937 "characterization and measurement of nano titanium dioxide part 1", by ISO/TC229 international nanotechnology Approved by the committee, it was officially released in December 2012.
