Embodiment 1

[0024] Carbon nanotube-two-dimensional titanium carbide composite material prepared by dry mixing with a powder mixer and 900 watts of microwave heating:

[0025] 1. Mixing: put two-dimensional titanium carbide (100mg) and ferrocene (100mg) into a 10 ml plastic vial, and mix them on a powder mixer at a speed of 72 rpm for 1 hour;

[0026] 2. Microwave heating: Place the ceramic container containing the mixed powder in step 1 in a microwave device, and heat it rapidly with a power of 900 watts for 40 seconds, so as to obtain a black fluffy product, which is the target product.

Embodiment 2

[0028] Preparation of carbon nanotube-two-dimensional titanium carbide composites by manual grinding and dry mixing, and 720W microwave heating:

[0029] 1. Mixing: Accurately weigh 50 mg each of two-dimensional titanium carbide and ferrocene, put them into an agate mortar and grind carefully for 15 minutes;

[0030] 2. Microwave heating: place the quartz container containing the mixed powder in step 1 in a microwave device, and heat it rapidly at a power of 720 watts for 20 seconds to obtain a black fluffy product, which is the target product.

Embodiment 3

[0032] Preparation of carbon nanotube-two-dimensional titanium carbide composites by manual grinding and wet mixing, and 900W microwave heating:

[0033] 1. Mixing: Put 1mL of acetone solution into a ceramic container containing two-dimensional titanium carbide (100mg) and nickelocene (100mg), and stir by hand until the acetone is volatilized;

[0034] 2. Microwave heating: Place the ceramic container containing the mixed powder in step 1 in a microwave device, and heat it rapidly at a power of 900 watts for 40 seconds to obtain a black fluffy product with a weight of about 180 mg;

[0035] 3. Mix the powder in step 2 with an equal amount of nickelocene, and then repeat steps 1 and 2 to obtain a larger amount of black fluffy product than in step 2, with a weight of about 300 mg.

Abstract

The invention relates to a method for rapidly preparing a carbon nanotube-two-dimensional titanium carbide composite material, and belongs to the field of material preparation. According to the method, two-dimensional titanium carbide and metallocene powder (ferrocene, nickelocene and cobaltocene) are mixed uniformly; and then the carbon nanotube-two-dimensional titanium carbide composite material is prepared rapidly by adopting a microwave heating method. The preparation method is simple in method, low in cost, and capable of rapidly preparing a target product at a normal-temperature environment, without requiring a high temperature, a vacuum system, an inert protection apparatus, a carbon source and a catalyst; in addition, by virtue of the microwave heating method, industrial large-scale production can be realized conveniently; and the prepared carbon nanotube-two-dimensional titanium carbide composite material can be used in the fields of energy storage, catalysis, sensing, adsorption and the like, and has a highly remarkable application value.

Description

technical field [0001] The invention relates to a method for rapidly preparing a carbon nanotube-two-dimensional titanium carbide composite material, belonging to the field of material preparation. Background technique [0002] In recent years, a new type of two-dimensional semiconductor material, MXenes, has attracted extensive attention from material researchers (Naguib, M., et al., Advanced Materials, 2014.26(7):992-1005). MXenes is based on the weak combination between the A sheet and the MX sheet in the MAX phase (M-early transition metal, A-ⅢA or IVA group elements, X-carbon and / or nitrogen), and the etchant (such as HF , LiF+HCL, NH 4 HF 2 ) A new type of two-dimensional nano-carbide or carbonitride prepared by ablation of the A primary layer in the MAX phase, which has a larger specific surface area and a narrower bandgap width. The study found that MXene, as a two-dimensional layered material with good electrical conductivity and adjustable surface functional gro...
