Problems solved by technology

Although titanium silicide was used as the precursor, titanium dioxide nanowires or nanobelts were not obtained after hydrothermal, pickling, and calcination.
Therefore, the preparation method of sea urchin-shaped rutile nano-titanium oxide with simple preparation process, easy control and low cost, which is titanium silicide as the precursor, has not been reported yet.

Abstract

The invention relates to the field of environmental protection and clean energy, particularly to a preparation method of urchin-like rutile type nano titanium oxide. According to the method, titanium silicide is taken as a precursor, urchin-like rutile type titanium oxide with the relatively uniform shape and good dispersity can be obtained through a hydrothermal reaction at the temperature of 180-210 DEG C, the single particle size is about 2 microns, and the urchin-like rutile type nano titanium oxide is formed by self-assembly of needle-like or rod-like rutile type titanium oxide. The preparation method is simple, reaction conditions are easy to control, the high-temperature calcination step adopted in a traditional method is omitted, energy consumption can be reduced, and the rutile type titanium oxide has very important use in the field of environmental science and new energy.

Description

technical field [0001] The invention relates to the fields of environmental protection and clean energy, in particular to a preparation method of sea urchin-shaped rutile nano-titanium oxide. Background technique [0002] Nano-TiO 2 Introduced in the late 1980s, it has very unique properties due to its small particle size, large specific surface area, and large proportion of interface atoms. For example: excellent UV shielding effect, transparent and non-toxic, peculiar color effect and photocatalysis, etc. TiO 2 It has broad application prospects in the automotive industry, anti-sun cosmetics, advanced coatings, wastewater treatment, sterilization, environmental protection, adsorbents and functional ceramic materials. Therefore, it has aroused people's widespread attention, and in-depth research has been carried out on its preparation, performance and application. [0003] Currently, TiO 2 The preparation method is relatively mature, and there are various methods, whic...
