Embodiment 1

[0050] Add an appropriate amount of liquid nitrogen to a 100mL beaker, then add 10mL of titanium tetrachloride drop by drop, then add 10mL of deionized water dropwise, shake the beaker constantly to get a yellow colloid, let the colloid stand, and when the temperature rises to room temperature, the colloid Transfer to a 100mL reaction kettle equipped with 0.09g copper sheet, heat to 160°C, and keep it for 24h, take it out, filter under reduced pressure, wash with deionized water and absolute ethanol alternately, dry in an oven at 60°C for 12h, and the target is obtained things.

[0051] Characterize the target and test its antibacterial effect.

Embodiment 2 to 7

[0053] The difference from Example 1 is only the amount of copper added, which are 1.19g, 2.38g, 2.59g, 3g, 4g, 6g respectively, and the rest of the steps are the same.

Embodiment 8

[0055] Add an appropriate amount of liquid nitrogen to a 100mL beaker, then add 10mL of titanium tetrachloride drop by drop, then add 10mL of deionized water dropwise, shake the beaker constantly to get a yellow colloid, let the colloid stand, and when the temperature rises to room temperature, the colloid Transfer to a 100mL reaction kettle with 3g of copper sheet, heat to 100°C, and keep it for 36h, take it out, filter under reduced pressure, wash with deionized water and absolute ethanol alternately, and dry in an oven at 60°C for 12h to obtain the target product .

[0056] Characterize the target and test its antibacterial effect.

Abstract

The invention provides a Cu2+1O / Cu2Cl(OH)3 / TiO2 ternary complex and a preparation method thereof. The ternary complex solves the problem that the existing photocatalyst has a narrow spectral response range and poor photocatalytic bacteriostasis effects. The Cu2+1O / Cu2Cl(OH)3 / TiO2 ternary complex is a nano-particle having a heterojunction structure composed of rutile TiO2, cuprite red Cu2+1O and Cu2Cl(OH)3 and has the particle size of 80-2000 nm. The molar ratio of titanium atoms to copper atoms in the ternary complex is 65 to 1: 1 and preferably, the molar ratio is 65 to 2: 1. The complex is used as a photocatalyst for inhibition of bacteria or degradation of organic matters. Preferably, the wavelength for photocatalysis is 300 to 1200 nm.

Description

technical field [0001] The invention relates to the field of biochemical technology, in particular to Cu 2+1 O / Cu 2 Cl(OH) 3 / TiO 2 Ternary complexes and methods for their preparation. Background technique [0002] Since British scientists Fleming, Flory and Chain won the Nobel Prize for their discovery of antibiotics-penicillin and its clinical utility in the 20th century, antibiotics have played a huge role in controlling human infectious diseases. So far, there are many kinds of antibiotics, and the quantity is huge. According to statistics, the annual consumption of antibiotics in the world can reach 100,000-200,000 tons, while my country is a big country in the production and consumption of antibiotics. For example, my country's penicillin production accounts for almost 70% of the world's total, and among the top 15 drugs in use and sales, 10 are antibiotics. Technology is a double-edged sword. The invention and application of antibiotics is one of the greatest ac...
