Problems solved by technology

The general steps of these synthetic methods are first to InCl 3 Waiting for indium salt to transform into In(OH) under certain conditions 3 , and then through In(OH) 3 Decompose at high temperature to produce In 2 o 3 .This kind of method is simple and easy to implement, but for effective control of In 2 o 3 There are still great difficulties in the morphology and structure of In 2 o 3 The preparation method of the material still has important scientific and practical significance

Embodiment 1

[0025] Firstly, indium nitrate pentahydrate was weighed and dissolved in DMF to prepare 10 ml of a solution with a concentration of 0.05 moles per liter. Then terephthalic acid was weighed and dissolved in DMF to prepare 10 ml of a solution with a concentration of 0.05 moles per liter. Then the above two solutions were mixed and mixed at 50 o C under stirring for 20 minutes to obtain a milky white cloudy liquid. After the above turbid solution was centrifuged at 3000 rpm for 10 minutes, the colorless solution in the centrifuge tube was removed to obtain a milky white precipitated product, which was indium(III)-terephthalic acid complex. Successively use DMF and deionized water to ultrasonically clean the precipitated product three times and o Tumble dry at C. The dried complex was transferred to a crucible and placed in a muffle furnace. with 1 o C / min heating rate from room temperature to 500 o C and keep warm for 50 minutes, and naturally cool down to room temperature ...

Embodiment 2

[0027] Firstly, indium nitrate pentahydrate was weighed and dissolved in DMF to prepare 10 ml of a solution with a concentration of 0.1 moles per liter. Then terephthalic acid was weighed and dissolved in DMF to prepare 10 ml of a solution with a concentration of 0.1 moles per liter. Then the above two solutions were mixed and mixed at 50 o C under stirring for 30 minutes to obtain a milky white cloudy solution. After the above turbid solution was centrifuged at 4000 rpm for 15 minutes, the colorless solution in the centrifuge tube was removed to obtain a milky white precipitated product, which was indium(III)-terephthalic acid complex. Successively use DMF and deionized water to ultrasonically clean the precipitated product three times and o Tumble dry at C. The dried complex was transferred to a crucible and placed in a muffle furnace. to 2 o C / min heating rate from room temperature to 400 o C and keep warm for 80 minutes, and naturally cool down to room temperature to...

Embodiment 3

[0029] Firstly, indium nitrate pentahydrate was weighed and dissolved in DMF to prepare 10 ml of a solution with a concentration of 0.2 moles per liter. Then terephthalic acid was weighed and dissolved in DMF to prepare 10 ml of a solution with a concentration of 0.2 moles per liter. Then the above two solutions were mixed and mixed at 50 o C under stirring for 30 minutes to obtain a milky white cloudy solution. After the above turbid solution was centrifuged at 4000 rpm for 15 minutes, the colorless solution in the centrifuge tube was removed to obtain a milky white precipitated product, which was indium(III)-terephthalic acid complex. Successively use DMF and deionized water to ultrasonically clean the precipitated product three times and o Tumble dry at C. The dried complex was transferred to a crucible and placed in a muffle furnace. to 2 o C / min heating rate from room temperature to 500 o C and keep warm for 60 minutes, and naturally cool down to room temperature to...

Abstract

The invention relates to hexagonal-tube-shaped indium oxide and a preparation method thereof, and belongs to the technical field of inorganic oxide semiconductor material preparation.Indium oxide is prepared with an indium (III)-terephthalic acid complex serving as the precursor, and the appearance and size of indium oxide are controlled.The method specifically includes the following steps of firstly, mixing indium nitrate and terephthalic acid in an N,N'-dimethylformamide (DMF) solution to be heated and stirred to obtain the indium (III)-terephthalic acid complex, and further conducting centrifugal separating, washing and drying to obtain the indium (III)-terephthalic acid complex to be subjected to pyrolysis to prepare an indium oxide material.The indium oxide and the preparation method have the advantages that the preparation process is simple and easy to implement, the appearance and structure of obtained indium oxide can be effectively controlled, the obtained product has good degrading capacity for 4-chlorophenol, and good application prospects are achieved in the field of sewage treatment and the like.

Description

technical field [0001] The invention relates to an indium oxide hexagonal tube with a complex as a precursor and a preparation method thereof, belonging to the technical field of preparation of inorganic oxide semiconductor materials. Background technique [0002] Environmental pollution and energy shortage are major challenges faced by human beings at present, and effective use of solar energy is one of the important methods to solve this problem. Among them, using semiconductor materials as photocatalysts, using solar energy to split water and degrade organic pollutants and other photocatalytic processes is an important way to effectively utilize solar energy, and has attracted extensive attention from scientists. In the process of photocatalysis, the performance of the catalyst is an important factor, so the development and preparation of stable and efficient photocatalysts is a current research hotspot. Indium oxide (In 2 o 3 ) is an important n Type semiconductor ma...
