Embodiment 1

[0026] Weigh 0.06g of titanium carbide, ultrasonically disperse it into 16mL of distilled water, add 4mL of ethylenediamine, disperse for 30 minutes, put it into a 50mL hydrothermal reaction kettle, set the temperature at 180°C for 6 hours, then take it out and let it cool naturally to 20°C, pour it into a centrifuge tube for centrifugation, pickle twice with 2% dilute hydrochloric acid, wash three times with absolute ethanol and distilled water, and dry in a constant temperature drying oven at a temperature of 70°C for 12 hours to obtain the product . Natural cooling to 20°C before subsequent operations, temperature control and cooling methods can enhance the synergistic effect of C and N double doping, making C and N doped into the lattice of titanium oxide, which enhances the response of titanium oxide to visible light. Further improve the catalytic degradation ability.

Abstract

A preparation method of double-doped rutile TiO2 nanorods belongs to the technical field of TiO2 nano polymers and comprises: dispersing titanium carbide as a raw material in water, adding ethylenediamine, dispersing for 20-30 min, adding the dispersed liquid into a reactor, allowing reaction at 170-190 DEG C for 5-6 h, taking out, cooling to 20 DEG C, centrifuging, washing, and drying to obtain the double-doped rutile TiO2 nanorods. The preparation method is simple and provides one-step synthesis of the rutile TiO2 nanorods doped with C and N.

Description

technical field [0001] The present invention belongs to TiO 2 The technical field of nanopolymers, involving the rutile phase TiO 2 Doping of nanorods, specifically involving a doubly doped rutile phase TiO 2 Preparation method of nanorods. The preparation method of the present invention realizes one-step synthesis of rutile phase TiO doped with C and N elements 2 Nano stave. Background technique [0002] With the economic tide of reform and opening-up sweeping across the country for 30 to 40 years, environmental and energy issues have seriously restricted the sustained and rapid development of my country's economy. In recent years, material studies have shown that: TiO 2 As a wide-bandgap semiconductor, it has many advantages in the field of photochemistry and photovoltaic cells, and is the best material to solve the above two problems. [0003] Titanium dioxide (TiO 2 ) semiconductor functional materials, due to their low cost, non-toxicity, high surface activity an...
