Embodiment 1
[0026] A preparation method of methane-carbon dioxide reforming synthesis gas nickel-based catalyst, comprising:
[0027] (1) 0.80g trimesic acid (0.0038mol, 210.14g / mol) and 1.10g nickel nitrate hexahydrate (0.0038mol, 290.81g / mol) (the molar ratio of trimesic acid and nickel nitrate is 1:1 ) was dissolved in 30 mL of ethanol, and then the above-mentioned alcohol solution was transferred into a hydrothermal reaction kettle, and the reaction was carried out at 150 °C for 48 h. After cooling, the solid was separated by centrifugation and washed three times with 30 mL of ethanol. The obtained solid was dried in an oven at 100° C. for 12 h, and ground to obtain a Ni-based organic framework material.
[0028] (2) Dissolve 0.20 g of ethyl orthosilicate (0.00096 mol, 208.33 g / mol) in 1 mL of ethanol, then weigh 0.50 g of the above Ni-based organic framework material and add it to the alcoholic solution of ethyl orthosilicate, and shake sufficiently 30min, then stood at room tempera...
