Embodiment 1
[0024] Cut the pure nickel mesh purchased in the market into strips with a size of 1cm×2cm, soak in acetone for 30 minutes and ultrasonic for 5 minutes, then rinse with deionized water, and then soak in 2M / L hydrochloric acid After 30 minutes, rinse with deionized water and ethanol three times respectively, and then dry naturally for later use. Select a piece of cleaned foamed nickel, measure 250uL phytic acid (analytical pure) with a titration gun, apply it manually on the surface of the foamed nickel, and dry it in an oven at 60 degrees Celsius for 12 hours. The dried sample is the PA / Ni precursor loaded with phytic acid. Take out a piece of nickel foam loaded with PA / Ni precursor after drying, place it in a quartz boat and place it in the central temperature zone of the vacuum tube furnace, continuously feed argon gas at an appropriate flow rate, and set the heating rate at 5°C / min The program raised the temperature up to 700°C and kept it warm for two hours. After waiting...
