Example Embodiment
[0053] Example 1
[0054] Application method of magnetic molybdenum-based catalyst in p-nitrophenol catalysis:
[0055] (1) Add 200 mL of p-nitrophenol solution with a concentration of 0.12mM in the conical flask;
[0056] (2) Add 0.54 g of sodium borohydride to the solution of step (1);
[0057] (3) Add 1 mL of the catalyst aqueous solution with a concentration of 4 mg / mL to the solution of step (2);
[0058] (4) The conical flask containing the solution described in step (3) is placed in a shaker for catalytic reduction reaction, the shaker rotates at 200 rpm, and the reaction temperature is 25°C.
[0059] The aqueous catalyst solution contains water and a magnetic molybdenum-based catalyst.
[0060] The preparation method of the magnetic molybdenum-based catalyst in this embodiment is as follows:
[0061] (a) Disperse 1 g of magnetic nano ferroferric oxide in 300 mL of water to obtain a ferroferric oxide dispersion;
[0062] (b) Add 10g of ammonium molybdate tetrahydrate, 18g of thiourea...
Example Embodiment
[0065] Example 2
[0066] Compared with Example 1, this embodiment does not add nickel chloride in step (b) of the preparation process of the magnetic molybdenum-based catalyst, and other conditions are completely the same as those of Example 1.
Example Embodiment
