Examples
Embodiment 1
[0020] Add 3.3 g of resorcinol to a mixed solution of 2.5 g of F127 in 30 g of ethanol and deionized water (mass ratio of 1:1), and mix well. 0.8 g of HCl (37 wt%) was added as a catalyst for the polycondensation reaction, and after stirring for 1 hour, 3 g of formaldehyde solution (37 wt%) was added and stirring was continued for 2 hours. The resulting solution was aged at room temperature for 96 hours until it was separated into two layers; the upper layer was removed and the lower polymer phase was stirred for 0.5 hours. After the product was cured at 80°C for 48 hours, it was heated from room temperature to 350°C at a heating rate of 1°C / min for 2 hours under a nitrogen atmosphere, and then heated to 800°C at a heating rate of 1°C / min for 2 hours. The resulting product was named OMC.
[0021] The pore structure properties of the product are: specific surface area 702m 2 / g, pore volume 0.63cm 3 / g, pore size 4.7nm.
Embodiment 2
[0023] In a mixed solution of 2.5 g of F127 dissolved in 30 g of ethanol and deionized water (mass ratio of 1:1), 3.3 g of resorcinol and 1.04 g of phosphoric acid (85 wt%) were added and mixed uniformly. 0.8 g of HCl (37 wt%) was added as a catalyst for the polycondensation reaction, and after stirring for 1 hour, 3 g of formaldehyde solution (37 wt%) was added and stirring was continued for 2 hours. The resulting solution was aged at room temperature for 96 hours until it was separated into two layers; the upper layer was removed and the lower polymer phase was stirred for 0.5 hours. After the product was cured at 80°C for 48 hours, it was heated from room temperature to 350°C at a heating rate of 1°C / min for 2 hours under a nitrogen atmosphere, and then heated to 800°C at a heating rate of 1°C / min for 2 hours. The resulting product was named P0.3-OMC.
[0024] The pore structure of the product is: specific surface area 614m 2 / g, pore volume 0.59cm 3 / g, the pore size is 5.8n...
Embodiment 3
[0026] The preparation process is the same as in Example 2, except that the amount of phosphoric acid (85wt%) added is 1.75g. The resulting product was named P0.5-OMC.
[0027] The pore structure properties of the product are: specific surface area 610m 2 / g, pore volume 0.57cm 3 / g, the pore size is 5.9nm, and the phosphorus content is 1.42wt%.
