Embodiment 1
[0017] Preparation of platinum-supported nitrogen-doped graphene materials:
[0018] Disperse 500mg of carbon nitride into 8ml of distilled water, add an aqueous solution containing 70mg of potassium chloroplatinite, stir at 90°C for 1h, then slowly add sodium borohydride solution (NaBH 4 / Pd molar ratio is 3:1), stirred at room temperature for 4h, filtered, washed with distilled water, and vacuum dried at 90°C to obtain a nitrogen-doped graphene material loaded with 5% platinum.
[0019] The method that catalytic furfural is converted into furfuryl alcohol:
[0020] Accurately weigh 200 mg of furfural and 25 mg of nitrogen-doped graphene material loaded with 5% platinum (10% nitrogen content) and add them to the lining of the autoclave, and add 3 ml of water. After sealing the stainless steel autoclave, it was ventilated with hydrogen for 3 times, and then flushed with 1MPa hydrogen at room temperature. Preheat the oil bath to the required temperature, put it into the autoc...
Embodiment 2~10
[0023] The difference from Example 1 lies in the reaction temperature, hydrogen pressure, platinum loading and the nitrogen content of the nitrogen-doped nitrogen graphene material. The results are shown in Table 1.
