Method of activating boron nitride
A method of activating boron nitride comprises exposing the boron nitride to a fluid enabling —OH hydroxyl radicals and/or H 3 O + to be delivered and creating B—OH bonds and/or NH 2 bonds in the boron nitride, and eliminating the fluid and recovering the activated boron nitride.
1. A method for activating boron nitride, the method comprising:
exposing the boron nitride to a fluid enabling —OH hydroxyl radicals and/or H 3 O + ions to be provided and creating B—OH bonds and/or NH 2 bonds in the boron nitride; and
eliminating the fluid and recovering the activated boron nitride, wherein the fluid is an acid solution or a basic solution.
2. The method according to claim 1 , further comprising subjecting the boron nitride and the fluid to an electric field.
3. The method according to claim 1 , wherein iron is further immersed in the fluid.
4. The method according to claim 1 , wherein the fluid is a gas.
5. The method according to claim 1 , wherein the boron nitride is crystallized in hexagonal form.
6. The method according to claim 1 , wherein the boron nitride is turbostratic.
7. The method according to claim 1 , wherein the boron nitride is in a powdery form.
8. The method according to claim 1 , wherein the boron nitride comprises percolated grains of boron nitride.
9. The method according to claim 1 , wherein the boron nitride has at least one additive from the following list: oxygen, boron oxide, calcium borate, boric acid.
10. The method according to claim 1 , wherein the boron nitride is associated with at least one of a polymer, ion-conducting polymer, PVA, and boric acid.
11. The method according to claim 1 , wherein the boron nitride is inserted into a polymeric membrane before activation.
12. The method according to claim 1 , wherein the activated boron nitride is incorporated into a polymeric membrane before being used for making a fuel cell, an electrolyzer or an accumulator.
13. The method according to claim 1 , further comprising rinsing the activated boron nitride.
14. The method according to claim 1 , wherein exposing the boron nitride to the fluid comprises exposing the boron nitride to the fluid for a duration ranging from 10 hours to 50 hours.
15. The method according to claim 1 , wherein the eliminating the fluid comprises eliminating the fluid to a residual content within the activated boron nitride of less than 5%.
16. The method according to claim 1 , wherein exposing the boron nitride to the fluid comprises exposing the boron nitride to the fluid for a duration ranging from 15 hours to 45 hours.
