Embodiment 1

[0024] 0.3g Co(NO 3 ) 2 ·6H 2 O (1mmol) and 0.06g CO(NH 2 ) 2 (1mmol) were dissolved in 10mL twice distilled water to form a uniform solution, and CO(NH 2 ) 2 The solution was added dropwise to the Co(NO 3 ) 2 solution, and then the mixed solution was transferred to a high-pressure reactor. Put the autoclave into an oven, control the reaction temperature to 95° C., and take out the autoclave after hydrothermal reaction for 6 hours, and cool it for 30 minutes. A pink precipitate was obtained by filtering with a 450 μm mixed cellulose membrane, and the obtained precipitate was washed several times with double distilled water and absolute ethanol in sequence, and then dried at 60° C. for 6 hours to obtain a pink precursor. Then put the pink precursor into the tube furnace, the temperature is raised to 200°C at a rate of 1°C / min, and kept at 200°C for 30 minutes to obtain a black powder, which is Co 3 o 4 Nanowires.

Embodiment 2

[0027] Weigh 0.24g CoCl 2 ·6H 2 O(1mmol) and 0.3g CO(NH 2 ) 2 (5mmol) were dissolved in 10mL twice distilled water to form a uniform solution. CO(NH 2 ) 2 The solution was added dropwise to the CoCl 2 solution, and then the mixed solution was transferred to a high-pressure reactor. Put the autoclave into an oven, control the reaction temperature to 110° C., and take out the autoclave after hydrothermal reaction for 8 hours, and cool it for 30 minutes. A pink precipitate was obtained by filtering with a 450 μm mixed cellulose membrane, and the obtained precipitate was washed several times with double distilled water and absolute ethanol in sequence, and then dried at 60° C. for 8 hours to obtain a pink precursor. Then put the pink precursor into the tube furnace, the temperature is raised to 250°C at a rate of 1°C / min, and kept at 250°C for 60 minutes to obtain a black powder, which is Co 3 o 4 Nanowires.

Embodiment 3

[0030] Weigh 0.3g Co(NO 3 ) 2 ·6H 2 O(1mmol) and 0.3g CO(NH 2 ) 2 (5mmol) were dissolved in 10mL twice distilled water to form a uniform solution. CO(NH 2 ) 2 The solution was added dropwise to the Co(NO 3 ) 2 solution, and then the mixed solution was transferred to a high-pressure reactor. Put the autoclave into an oven, control the reaction temperature to 120° C., and take out the autoclave after hydrothermal reaction for 8 hours, and cool it for 30 minutes. A pink precipitate was obtained by filtering with a 450 μm mixed cellulose membrane, and the obtained precipitate was washed several times with double distilled water and absolute ethanol in sequence, and then dried at 60° C. for 10 hours to obtain a pink precursor. Then put the pink precursor into a tube furnace, raise the temperature to 300°C at a rate of 2°C / min, and keep it at 300°C for 100 minutes to obtain a black powder, which is Co 3 o 4 Nanowires.

Abstract

The invention discloses a method for doping a Co3O4 nanowire with Sn. The method comprises the following steps: adding the Co3O4 nanowire, oleylamine and oleic acid into an organic solvent, heating to 80-100 DEG C, then, adding SnCl2, and reacting for 1-3 hours to obtain a Sn-doped Co3O4 nanowire. The method disclosed by the invention is used for successfully doping the Sn element into Co3O4, is simple to operate, almost free of influence on Co3O4 morphology, and capable of remarkably improving conductivity of Co3O4 after doping Sn.

Description

technical field [0001] The invention belongs to the field of inorganic nanomaterial doping, in particular to Co 3 o 4 A method for doping nanowires with Sn. Background technique [0002] One-dimensional nanostructures, due to their interesting properties and unique applications, have always been the subject of intensive research by scholars. co 3 o 4 As an important transition metal oxide, it has attracted attention due to its wide application in catalysts, electrochemical properties, magnetic materials, field emission materials, sensors and other fields. However, the current research on Co with different morphologies and sizes 3 o 4 The research and application of materials can no longer meet the ever-expanding requirements in many fields. In order to expand Co. 3 o 4 performance, mixing or doping with other elements is the synthesis of Co 3 o 4 An efficient approach to composite materials. In the past ten years, many Co 3 o 4 Composite material, Co. 3 o 4 C...
