Embodiment 1
[0026] Weigh 46mg of ammonium molybdate, 0.5g of glucose and 90mg of polystyrene balls in 40mL of deionized water, mix them evenly and fully dissolve, add the obtained clear solution into a 50mL polytetrafluoroethylene reactor, and place the reactor in Hydrothermal reaction in an oven at 180°C for 12 hours, then naturally cooled to room temperature, and the product was centrifuged, washed and dried to obtain the precursor;
[0027] Put the precursor into an open quartz boat, and place the quartz boat between the two electrodes in the cold plasma processing equipment; fill the cold plasma processing equipment with argon as an initiating gas, and place the A voltage of 500V is applied between them and treated for 10 minutes to obtain a non-noble metal molybdenum carbide catalyst.
[0028] figure 2 and image 3 They are scanning electron micrographs and X-ray diffraction spectra of the product, respectively. From figure 2 It can be seen that the molybdenum carbide catalyst ...
Embodiment 2
[0031] Weigh 46mg of ammonium molybdate, 0.5g of glucose and 90mg of polystyrene balls in 40mL of deionized water, mix them evenly and fully dissolve, add the obtained clear solution into a 50mL polytetrafluoroethylene reactor, and place the reactor in Hydrothermal reaction was carried out in an oven at 180°C for 12 hours, then naturally cooled to room temperature, and the product was centrifuged, washed and dried to obtain a precursor.
[0032] Put the precursor into an open quartz boat, and place the quartz boat between the two electrodes in the cold plasma processing equipment; fill the cold plasma processing equipment with argon as an initiating gas, and place the A voltage of 1000V was applied between them, and the non-noble metal molybdenum carbide catalyst was prepared after treatment for 20 minutes.
[0033] The morphology of the samples obtained in this example is similar to that of Example 1, with uniform particle size, good dispersion and perfect crystals.
