Embodiment 1

[0017] Mix 20 milliliters of deionized aqueous solution containing 3 grams of rotten apple juice, 5 milliliters of sodium oleate solution (10 mmol / L) and 5 milliliters of P123 solution (1 mmol / L), and stir until uniformly mixed, and the mixed transparent liquid Put it into a 50 ml polytetrafluoroethylene-lined stainless steel water heating tank, tighten the lid, put the water heating tank in an oven at 150°C, keep it warm for 10 hours, take the water heating tank out of the oven, and cool it in the air until room temperature, then open the water-heated jar, pour out the mixture inside, and centrifuge in a centrifuge at 8000 rpm to obtain a precipitate, which is then repeatedly washed with water and ethanol to obtain a hollow carbon bowl.

Embodiment 2

[0019] 20 milliliters of deionized aqueous solution containing 5 grams of grape juice, 10 milliliters of sodium dodecylbenzene sulfonate solution (10mmol / L) and 10 milliliters of F127 solution (1mmol / L) are mixed, and stir until mixing evenly, will Put the mixed transparent liquid into an 80ml polytetrafluoroethylene-lined stainless steel water heating tank. After tightening the lid, put the water heating tank in an oven at 130°C. After 20 hours of heat preservation, take the water heating tank out of the oven and place Cool to room temperature in the air, then open the water heat tank, pour out the mixture inside, and centrifuge in a centrifuge at 8000 rpm to obtain a precipitate, then repeatedly wash with water and ethanol to obtain a hollow carbon bowl.

Embodiment 3

[0021] 20 milliliters of deionized water containing 3 grams of sugarcane juice, 20 milliliters of sodium stearate solution (10mmol / L) and 20 milliliters of Tween 40 solution (1mmol / L) were mixed, and stirred until uniformly mixed, the mixed Put the transparent liquid into an 80ml polytetrafluoroethylene-lined stainless steel water heating tank. After tightening the lid, put the water heating tank in an oven at 120°C. After keeping it warm for 48 hours, take the water heating tank out of the oven and place it in the air Cool to room temperature, then open the hydrothermal jar, pour out the mixture inside, and centrifuge in a centrifuge at 8000 rpm to obtain a precipitate, then repeatedly wash with water and ethanol to obtain a hollow carbon bowl.

Abstract

The invention discloses a preparation method of hollow carbon bowl powder, and belongs to the technical field of preparation of inorganic materials. According to the method, a direct biological raw material or waste is adopted as a carbon source, a soft template is used as a template, and the hollow carbon bowl powder material with high dispersity, controllable particle size distribution and size,an inner hollow structure, morphology of a concave bowl-shaped structure, controllable wall thickness of the carbon bowl, and the like is prepared. The preparation method comprises the following steps: taking the carbon source, deionized water and the soft template agent as raw materials, respectively dissolving the carbon source and two surfactants in the deionized water to form three solutions,then mixing the three solutions according to a certain ratio, uniformly carrying out stirring to obtain a mixed solution, putting the mixed solution into a hydrothermal reaction kettle, and carryingout heating for a reaction to obtain a product. The method has the advantage that the direct biological raw material or biological waste is used as the carbon source, and aims to provide the novel utilization mode of biological wastes, so that emission of wastes is reduced, the wastes are converted into the functional carbon material, the process is simple, and the preparing and removing processesof a template in a hard template method is omitted.

Description

technical field [0001] The invention belongs to the technical field of preparation of inorganic materials, and in particular relates to a preparation method of a new hollow bowl-shaped carbon material. Background technique [0002] In recent years, the research on carbon materials has been quite active, and various carbon crystals, needle-shaped, rod-shaped, tubular, spherical, and hollow spherical shapes have emerged one after another, which is a very important field in modern material science. Carbon materials with different structures and shapes such as graphene, carbon nanotubes, fullerenes, carbon nanofibers, carbon microspheres, and carbon hollow spheres have become the focus of research in the field of materials research. Among many carbon materials, hollow structure carbon materials have attracted more and more attention due to their unique structure, and are one of the most widely and deeply studied carbon materials. Hollow bowl-shaped carbon material is a further ...
