Is it possible only use ammonia as gas for activated carbon with using N2 gas before? Thank you. So far when i read the paper, they only use ammonia for doping the nitrogen into activated carbon after the calcination using N2 gas. Thank you.
I tried to do the amidation for activated carbon, by using some coupling agents, but it did not work. I used NHS/EDC, HATU-DIPEA, DCC with DMF as solvent. I analyzed the amount of nitrogen by...
