Embodiment 1

[0025] Example 1: Porous carbon supported nano-Cu

[0026] Synthetic raw materials: glucose, ethylenediamine, Cu(NO 3 ) 2? 3H 2 O (copper nitrate)

[0027] (1) Weigh 1g of glucose and 0.1g of Cu(NO 3 ) 2? 3H 2 O In a 100mL beaker, slowly add 10g of ethylenediamine dropwise and place the beaker in a heatable magnetic stirrer. The temperature of the magnetic stirrer was raised to 100° C., and the stirring was continued for 60 min until the medicine in the beaker was in a molten state.

[0028] (2) From the molten liquid mentioned in (1), take out a part of the solution and put it in a 120°C oven as sample A, and put the other part of the solution into a high-temperature reaction kettle and put it in a 120°C oven as sample B, and react for 48 hours. A dark brown bulky solid was obtained, and sample B was dark brown dense solid.

[0029] (3) Grind the sample A and sample B obtained in (2) with a mortar, and divide them into two crucibles, and then put them under N 2 Heat ...

[0031] Experimental example 2: Porous carbon supported nano-Ni alloy

[0032] Synthetic raw materials: glucose, polyethyleneimine (PEI), Ni(NO 3 ) 2? 6H 2 o

[0033] (1) Weigh 10g glucose, 0.1gPEI, 0.1gNi(NO 3 ) 2? 6H 2 O in a 100mL beaker, then place the beaker in a heatable magnetic stirrer. The temperature of the magnetic stirrer was raised to 220° C., and the stirring was continued for 60 min until the medicine in the beaker was in a molten state.

[0034] (2) Afterwards, put the beaker into an oven at 250°C and react for 1 hour to obtain a dark brown puffy solid.

[0035] (3) Grind the product obtained in (2) with a mortar and put it in a crucible. The product obtained by the reaction was heated at 250°C in 5% H 2 / N 2 Under the condition of heat treatment for 24 hours, the porous carbon-supported nano-Ni particles are obtained.

experiment example 3

[0036] Experimental example 3: Porous carbon supported nano-TiO 2

[0037] Synthetic raw materials: sucrose, ethanolamine, TiOSO 4 (titanyl sulfate)

[0038] (1) Weigh 1g of sucrose and 5g of ethanolamine into a 100mL beaker, then place the beaker in a heatable magnetic stirrer. The temperature of the magnetic stirrer was raised to 100°C, and the stirring was continued until the medicine in the beaker was in a molten state.

[0039] (2) Weigh 10g TiOSO 4 Add it to the molten liquid described in (1), and continue to stir for 15 minutes until it reaches a molten state. Afterwards, the beaker was put into an oven at 160° C., and reacted for 40 hours to obtain a dark brown puffy solid.

[0040] (3) Grind the product obtained in (2) with a mortar and put it in a crucible. The product obtained by the reaction is in N 2 Heat treatment at 250°C for 24 hours under protection to obtain porous carbon-supported TiO 2 nanoparticles, XRD shows TiO 2 The particle size is 20nm, and the...

Abstract

The invention discloses a method for preparing a porous carbon-loaded nano-material, belongs to the technical field of porous material preparation, and particularly relates to a porous carbon-loaded nano-metal oxide or nano-metal material prepared by utilizing organic amine as a template by one-step in situ formation through high-temperature melting, charring and roasting treatment. According to the method, the pore size of porous carbon is regulated and controlled by different types of organic amine templates, the whole process has the advantage of simple one-step operation, low preparation cost and the like, and the prepared porous carbon-loaded nano-metal oxide or nano-metal material has a wide application prospect in industrial catalysis, water treatment, electrochemistry and other aspects.

Description

technical field [0001] The invention provides a preparation method of a novel porous carbon-loaded nanometer material, which belongs to the technical field of porous material preparation. Background technique [0002] Porous carbon materials have a high specific surface area, developed pore structure, more functional groups and strong adsorption capacity on the surface, and also have a series of advantages such as high temperature resistance, acid and alkali resistance, electrical conductivity and heat transfer, and can be adjusted The pore size and surface properties make porous carbon materials widely used in the fields of catalyst supports, supercapacitors, catalysts, and adsorbents. Currently, the commonly used method for preparing porous carbon materials is the template method. Furfuryl alcohol, ethylene, acrylonitrile, phenolic resin, resorcinol formaldehyde resin, acetonitrile, polypyrrole, bitumen and other aromatic compounds are used as carbon sources. The porogen ...
