Embodiment 1
[0024] (1) First, mix fly ash and NaOH (mass ratio 1:1) and melt at 500°C for 1 hour, then cool to obtain the mixture;
[0025] (2) Then, add distilled water to the mixture to dissolve, filter and take the supernatant for use, wherein the supernatant is aluminosilicate solution;
[0026] (3) Dissolve the surfactant P123 in distilled water, add 2M HCl until the pH is 0.9, and the molar ratio of each substance in the mixed precursor solution is 1Si:0.016P123:5.4HCl:200H 2 O, fully stirred at 35~40°C; after aging in an oven at 95°C for 24 hours, filter, wash, and dry;
[0027] (4) Finally, the dried material was calcined at 550°C for 5 hours, the heating rate was 1°C / min, and the powdered mesoporous material was obtained after cooling.
Embodiment 2
[0029] (1) First, mix fly ash and NaOH (mass ratio 1:1.2) and melt at 550°C for 1.5h, then cool to obtain the mixture;
[0030] (2) Then, add distilled water to the mixture to dissolve, filter and take the supernatant for use, wherein the supernatant is aluminosilicate solution;
[0031] (3) Dissolve the surfactant P123 in distilled water, add 2M HCl until the pH is 0.6, and the molar ratio of each substance in the mixed precursor solution is 1Si:0.016P123:17.3HCl:200H 2 O, fully stirred at 35~40°C; after aging in an oven at 95°C for 24 hours, filter, wash, and dry;
[0032] (4) Finally, the dried material was calcined at 550°C for 5 hours, the heating rate was 1°C / min, and the powdered mesoporous material was obtained after cooling.
Embodiment 3
[0034] (1) First, mix fly ash and NaOH (mass ratio 1:1.3) and melt at 600°C for 2 hours, cool to obtain the mixture; (2) Then, add distilled water to the mixture to dissolve, filter to get the supernatant The liquid is ready for use, wherein the supernatant is an aluminosilicate solution;
[0035] (3) Dissolve the surfactant P123 in distilled water, add 2M HCl until the pH is 0.3, and the molar ratio of each substance in the mixed precursor solution is 1Si:0.016P123:24.5HCl:200H 2 O, fully stirred at 35~40°C; after aging in an oven at 95°C for 24 hours, filter, wash, and dry;
[0036] (4) Finally, the dried material was calcined at 550°C for 5 hours, the heating rate was 1°C / min, and the powdered mesoporous material was obtained after cooling.
