Embodiment 1

[0028] First prepare a catalyst, a nano-aluminum-platinum catalyst, consisting of platinum powder and aluminum powder, the mass ratio of the platinum powder to aluminum powder is 1:8.5, the size of the platinum powder is 5nm, and the size of the aluminum powder is 4.0nm.

[0029] A kind of preparation method of nano aluminum platinum catalyst, its step:

[0030] (1) Grinding metal platinum into platinum powder with a size of 5nm, and grinding metal aluminum into aluminum powder with a size of 4.0nm;

[0031] (2) the platinum powder and the aluminum powder in the step (1) are mixed evenly according to the ratio of 1:8.5 according to the mass ratio, to obtain the mixed powder;

[0032] (3) compressing the mixed powder in step (2) with a tablet press, with a pressure of 137N, to obtain a mixed briquette;

[0033] (4) The mixed briquette in step (3) was placed in an aqueous sodium hydroxide solution with a mass concentration of 29% for 2 minutes to obtain a finished catalyst. Th...

Embodiment 2

[0035] Same as Example 1, the difference is that the size of the platinum powder is 3.5nm, and the size of the aluminum powder is 4.5nm. The prepared finished catalyst is loose and porous, with a density of 0.28g / cm 3 .

Embodiment 3
