Embodiment 1

[0027] With 4g Zn(CH 3 COO) 2 2H 2 O was used as a catalyst, 40 mL of absolute ethanol was used as a carbon source, put into a 60 mL stainless steel autoclave, heated to 600 °C at a heating rate of 10 °C / min, kept for 15 h, and then naturally cooled to room temperature. After the product was collected from the autoclave, it was washed successively with hydrochloric acid with a concentration of 5%-15%, distilled water and absolute ethanol, and finally the obtained black product was dried in a vacuum dryer at 60° C. for 6 hours. The obtained product was characterized and analyzed by transmission electron microscope (TEM), scanning electron microscope (SEM) and X-ray diffraction (XRD), and it was confirmed that the obtained product was a carbon tube with high purity, and its shape was straight carbon Microtubules, its content is about 95%.

[0028] The inventor selects different raw materials and operating conditions (all the other operating conditions are the same as embodime...

Abstract

The carbon tube synthesis process includes the programmed heating carbonization of carbon chain containing organic compound as carbon source with acetate as catalyst in the carbon source-to-catalyst ratio of 10 ml to 1 g-50 ml to 3 g inside a sealed reaction kettle, and purifying and drying the carbonized product. The present invention can obtain carbon tube with homogeneous and controllable size and rich hydrophilic radicals.

Description

technical field [0001] The invention belongs to the technical field of carbon materials, in particular to a method for synthesizing carbon tubes by a solvothermal method. Background technique [0002] Carbon nanotubes are the most studied tubular carbon materials. Since the discovery of carbon nanotubes by Iijima in 1991, carbon nanotubes have received extensive attention. Due to their unique thermal, electrical, magnetic and mechanical properties, carbon nanotubes have potential applications in many aspects, such as electrochemical devices, nanotweezers, gas storage, field emission devices, memory devices, thermal conductivity sensors and catalysts carrier etc. [0003] At present, the relatively mature methods for preparing carbon nanotubes mainly include catalytic pyrolysis, arc discharge, laser ablation, flow catalysis, and chemical vapor deposition. However, these synthetic methods are expensive in equipment, high in technical content, and complicated in operation. T...
