Synthesis and characterization of nitrogen-functionalized graphene oxide in high-temperature and high-pressure ammonia
A novel and efficient approach to the synthesis of nitrogen-functionalized graphene oxide (GO) using aqueous ammonia, NH3 (aq.), under high-temperature and high-pressure conditions was investigated. Nitrogen groups (N-groups) were incorporated in GO in different ways; by replacing the carbon (C) ato...
