Embodiment 1

[0038] 1) Dissolve 7.00g of sodium hydroxide and 12.00g of urea in 81ml of water and mix well to form a sodium hydroxide / urea solution; add 3.24g of microcrystalline cellulose to the obtained sodium hydroxide / urea mixture and mix well ; Then place the resulting mixture at -12°C for 12 hours to obtain a cellulose solution.

[0039] 2) At room temperature, mix 10 mL of the cellulose solution obtained in step 1) with 10 mL of 1-butyl-3-methylimidazolium tetrafluoroborate (ionic liquid, density about 1.22 g / ml), Wherein the mass ratio of cellulose to ionic liquid is about 1:37, then 0.33gCuCl 2 2H 2 O is added to the mixture and mixed evenly, where CuCl 2 2H 2 The mass ratio of O to the cellulose is about 1:0.95.

[0040] 3) Put the mixture obtained in step 2) into a microwave catalytic synthesizer (Xiangge Technology Co., Ltd., model XH-100A), turn on the power, and perform microwave treatment for 40 minutes at a temperature of 100±2°C. After the reaction was finished, the p...

[0046] In addition to placing the precursor obtained after the microwave reaction in a vacuum / atmosphere tube furnace (Tianjin Zhonghuan Experimental Electric Furnace Co., Ltd., SK-G08123K), nitrogen gas was introduced, the air in the furnace was exhausted, and the temperature was raised to 5°C / min. 800°C, after calcination treatment at 800°C for 3h, cooled to room temperature, followed the same method as in Example 1 to prepare a hybrid material of biomass carbon base, copper and cuprous oxide.

[0047] The composition and purity of the prepared hybrid materials were analyzed by X-ray diffraction, such as image 3 shown. The diffraction peak at 2θ=36.7° in the X-ray diffraction spectrum corresponds to the (111) crystal plane of cuprous oxide, while the peaks at 2θ=43.5° and 50.6° correspond to the (111) and (200) crystal planes of copper, respectively . The X-ray diffraction spectrum of the product shows that the product contains both cuprous oxide and copper, indicating th...

[0050] In addition to placing the precursor obtained after the microwave reaction in a vacuum / atmosphere tube furnace (Tianjin Zhonghuan Experimental Electric Furnace Co., Ltd., SK-G08123K), nitrogen gas was introduced, the air in the furnace was exhausted, and the temperature was raised to 5°C / min. 1000°C, after calcination treatment at 1000°C for 3h, cooled to room temperature, followed the same method as in Example 1 to prepare a hybrid material of biomass carbon-based and copper.

[0051] The composition and purity of the prepared hybrid materials were analyzed by X-ray diffraction, such as Figure 4 shown. The peaks at 2θ=43.5° and 50.6° in the X-ray diffraction spectrum correspond to the copper (111) and (200) crystal planes, respectively. The X-ray diffraction spectrum of the product shows that the product contains copper, indicating that the product is a hybrid material of biomass carbon-based and copper.

Description

technical field [0001] The invention relates to the field of synthesis of composite hybrid materials, in particular to a biomass carbon-based composite hybrid material and a preparation method thereof, in particular to a hybrid material of biomass carbon-based and copper and / or cuprous oxide and its preparation method. Background technique [0002] Carbon materials are widely used in metallurgy, chemical industry, machinery, electronics, aviation and other fields due to their excellent heat resistance, high thermal conductivity, good chemical inertness, and high electrical conductivity. In recent years, due to the shortage of fossil resources, the development and application of carbon materials have been limited. Biomass resources such as forestry biomass, agricultural waste, aquatic plants, energy plants, etc. are renewable resources and have become substitutes for fossil resources, and most of the biomass resources are rich in carbon elements, which have become the best c...
