Embodiment 1
[0019] 1.2358g of ammonium molybdate was dissolved in 60mL of deionized water, 0.4708g of 3-amino-1,2,4-triazole was added to the above solution, and a light yellow clear solution was obtained after fully dissolving; the above mixed solution was heated at 70°C Stirring was continued for 12h, and no precipitate was precipitated.
Embodiment 2
[0021] 1.2358g of ammonium molybdate was dissolved in 60mL of deionized water, 0.4708g of 3-amino-1,2,4-triazole was added to the above solution, and a light yellow clear solution was obtained after fully dissolving; the above mixed solution was heated at 70°C Continue to stir for 12 hours to obtain a light yellow precipitate, which is collected by filtration and dried at a temperature of 80°C; put the quartz boat containing the light yellow powder into a tube furnace, and set the temperature at 40 mL / min of argon and 20 mL / min of hydrogen In the mixed atmosphere, the temperature was raised to 460°C at a heating rate of 5°C / min, the temperature was kept constant for 4 hours, the gas was turned off, and the molybdenum carbide material was obtained after natural cooling. The prepared molybdenum carbide was characterized by SEM, and obtained figure 2 Nanowires.
Embodiment 3
[0023] 1.2358g of ammonium molybdate was dissolved in 60mL of deionized water, 0.7063g of 3-amino-1,2,4-triazole was added to the above solution, and a light yellow clear solution was obtained after fully dissolving; the above mixed solution was heated at 70°C Continue to stir for 12 hours to obtain a light yellow precipitate, which is collected by filtration and dried at a temperature of 80°C; put the quartz boat containing the light yellow powder into a tube furnace, and set the temperature at 40 mL / min of argon and 20 mL / min of hydrogen In the mixed atmosphere, the temperature was raised to 460°C at a heating rate of 5°C / min, the temperature was kept constant for 4 hours, the gas was turned off, and the molybdenum carbide material was obtained after natural cooling. The prepared molybdenum carbide was characterized by XRD and obtained figure 1 .
[0024] Example 3
[0025] 1.2358g of ammonium molybdate was dissolved in 60mL of deionized water, 0.7063g of 3-amino-1,2,4-tri...
