Embodiment 1

[0026] Taking the stoichiometric ratio of Cu(NO 3 ) 2 and Na 2 HPO 4 (where Cu(NO 3 ) 2 3.751g, Na 2 HPO 4 is 1.560g), add 80 milliliters of deionized water, stir vigorously, the pH value of the NaOH solution adjustment system of the obtained suspension is neutral with a concentration of 5mol / L, continue to stir, and finally the obtained suspension The solution was transferred to a 120 ml polytetrafluoroethylene reactor, and reacted at 120° C. for 6 hours. After the reaction was finished, the reaction vessel was taken out and cooled at room temperature. The obtained sample was suction-filtered, washed with deionized water and ethanol three times, and dried in an oven at 60°C for 12 hours. figure 1 is the electron micrograph of the obtained sample.

Embodiment 2

[0028] Taking the stoichiometric ratio of Cu(NO 3 ) 2 and Na 2 HPO 4 (where Cu(NO 3 ) 2 3.751g, Na 2 HPO 4 1.560g), add 80 milliliters of deionized water, vigorously stir, the pH value of the NaOH solution regulator system of 5mol / L for the obtained suspension is 4.0, continue to stir, finally the obtained suspension Transfer to a 120 ml polytetrafluoroethylene reactor, and react at 120° C. for 6 hours. After the reaction was finished, the reaction vessel was taken out and cooled at room temperature. The obtained sample was suction-filtered, washed with deionized water and ethanol three times, and dried in an oven at 60°C for 12 hours. figure 2 is the electron micrograph of the obtained sample.

Embodiment 3

[0030] Taking the stoichiometric ratio of Cu(NO 3 ) 2 and Na 2 HPO 4 (where Cu(NO 3 ) 2 3.751g, Na 2 HPO 4 1.560g), add 80 ml of deionized water, stir vigorously, adjust the pH value of the system to neutral with NaOH solution with a concentration of 5mol / L, and then put it into the reaction kettle for 12 hours at 120°C , the obtained sample was subjected to suction filtration, washed repeatedly with deionized water and ethanol three times, and then dried in an oven at 60° C. for 12 hours. image 3 is the X-ray diffraction pattern of the obtained sample.

Abstract

The invention relates to a near-infrared response photocatalysis material Cu2(OH)PO4 and a preparation method, the preparation method comprises the following steps: mixing Cu(NO3)2 and Na2HPO4 and adding in deionized water, adjusting the pH value of suspending liquid to 4-7, performing hydrothermal reaction for 6-12 hours at 120 DEG C, separating and purifying, and drying to obtain the product of micro-nano crystal having a quadrature structure, wherein the crystal length is 4-5 micrometers, the width is 1.4-1.6 micrometers, and the surface has ravine. The near-infrared response photocatalysis material Cu2(OH)PO4 has good photocatalysis performance under the near infrared irradiation (Lambda is greater than 800 nanometers), 90% of 2,4dichlorophenol can be degraded in six house, and the performance is excellent.

Description

technical field [0001] The invention relates to a photocatalytic material Cu with micro-nano near-infrared response 2 (OH)PO 4 The invention and a preparation method thereof belong to the synthesis field of micro-nano near-infrared photocatalytic powder materials. Background technique [0002] In recent years, energy and environmental issues have become increasingly prominent, which has seriously affected economic development. Environmental pollution has brought great harm to human production and life, especially the pollution of water resources has endangered human health, and there is an urgent need for feasible methods to treat sewage. The traditional method of water pollution control has the disadvantages of high energy consumption, complicated equipment, high cost, and easy to cause secondary pollution. Therefore, the development of a new, efficient and practical environmental protection treatment technology has become a research hotspot. [0003] With the deepening...
