Method for production of nanoporous activated carbons with high nitrogen contents, characterised in that chitosan is swelled, next it is subjected to protonisation and depolymerisation, then it is mixed with a solution of carbonates and heated in an atmosphere with low chemical reactivity. Afterwards, it is treated with acid, washed out, filtered off and dried. For the swelling, distilled water is used. Depolymerisation and protonisation are carried out using an aqueous solution of HC1. After the depolymerisation process, an aqueous solution of sodium carbonate is added. The heating is carried out under nitrogen at 600-800°C for at least 1 hour. After heating, HC1 or HNO3 is used. |
