Embodiment 1
[0025] 1) Weigh 8.2 mmol of hexadecylamine and add it to 100 mL of absolute ethanol, add 1.6 ml of deionized water with a pipette gun, and stir at 500 r / min for 30 min to obtain solution A.
[0026] 2) Use a pipette gun to pipette 4.45mL of isopropyl titanate into solution A, adjust the rotation speed to 300r / min, stir for 3 minutes to obtain suspension B, and place suspension B in the room for aging for 18 hours.
[0027] 3) The titanium dioxide in the suspension B was separated by centrifugation at a centrifugal speed of 7000r / min, and the separated solid matter was dried in an oven at 60°C to obtain titanium dioxide nanospheres.
[0028] 4) Take 100mg of titanium dioxide nanospheres and spread them on a corundum boat of 75×13×9mm, place the corundum boat in a high-temperature tube furnace, in 99.99wt% high-purity ammonia gas (flow rate of 200 standard ml / min) Heating to 700°C in a medium temperature, and keeping it warm for 4 hours, and getting titanium nitride nanospheres ...
