Embodiment 1
[0029] The preparation steps in the present embodiment are as follows:
[0030] (a) Under stirring, dissolve 0.1mol aluminum nitrate and 0.01mol nickel nitrate in 50 mL deionized water to form a uniformly mixed solution;
[0031] (b) Under constant temperature stirring at 70°C, add 165mL, 1M ammonium carbonate solution dropwise into the above solution to form a sol;
[0032] (c) Aging the above homogeneous sol at a constant temperature of 70°C for 24 hours, transferring to an oven and drying at 110°C for 12 hours;
[0033] (d) Calcinate the sample obtained in step c at 800 °C for 20 hours at a heating rate of 10 °C / min, and grind to obtain mesoporous NiAl 10 o 16 Material.
