Embodiment 1

[0022] Synthesis of carbon hollow tubes modified with iron at the top: 25 grams of polyvinyl alcohol and 10 grams of ferric oxalate were uniformly mixed, placed in a stainless steel autoclave, sealed and placed in a high-temperature furnace. Keep at high temperature for 10 hours, after cooling to room temperature, first rinse with absolute ethanol, then rinse with distilled water to remove impurities, and then vacuum dry at 40°C for 4 hours to obtain a carbon hollow tube with iron modified on the top, the morphology is shown in figure 1 (A).

Embodiment 2

[0024] Synthesis of carbon hollow tubes modified with iron at the top: 50 grams of polyvinyl alcohol and 20 grams of ferric oxalate were uniformly mixed, placed in a stainless steel autoclave, sealed and placed in a high-temperature furnace. Keep at temperature for 15 hours, after cooling to room temperature, first rinse with absolute ethanol, then rinse with distilled water to remove impurities, and then vacuum dry at 40°C for 4 hours to obtain a carbon hollow tube with iron modified on the top.

Embodiment 3

[0026] Synthesis of carbon hollow tubes modified with iron at the top: 30 grams of polyethylene glycol and 12 grams of ferric oxalate were uniformly mixed, placed in a stainless steel autoclave, sealed and placed in a high-temperature furnace, heated from room temperature to 350 ° C within 30 minutes, and Keep at this temperature for 12 hours, after cooling to room temperature, first rinse with absolute ethanol, then rinse with distilled water to remove impurities, and then vacuum dry at 40°C for 4 hours to obtain a carbon hollow tube with iron-top modification.

Abstract

The invention relates to a top modified transitional metal carbon hollow pipe material, and a preparation method and application thereof. The preparation method comprises the following steps of: placing a multi-hydroxyl polymer and an organic compound of transitional metal into a stainless steel high-pressure kettle; sealing the kettle; placing the kettle into a high-temperature furnace and heating the kettle to be from room temperature to 320 to 500 DEG C within 30 to 55 minutes; preserving the heat for 9 to 15 hours; cooling to room temperature; leaching with absolute ethanol; leaching with distilled water to remove impurities; and performing vacuum drying to obtain the material in which the transitional metal iron, cobalt or nickel is gathered at one end of a carbon hollow pipe. The material has high adsorption property; the preparation method is simple; the preparation condition is easy to control; and the top modified transitional metal carbon hollow pipe has high preparation reproducibility.

Description

technical field [0001] The invention relates to a carbon hollow tube material and its application in cigarettes, belonging to the technical field of tobacco. Background technique [0002] Smoking and health are issues of general concern to people, and the impact of harmful components such as hydrocyanic acid in mainstream cigarette smoke on human health has attracted much attention. Therefore, reducing the harmful components in the smoke, reducing the harm of smoking, and improving the quality and safety of cigarette products are issues that the tobacco industry must solve. High-quality, safe and low-hazard cigarettes have become the development trend of international cigarettes. The previous research work shows that: due to the complex sources of harmful components in cigarette smoke, tar reduction can only partially suppress the harmful components in cigarette smoke, and the harmful components in smoke cannot be effectively removed only by reducing the amount of tar in cig...
