Mesoporous carbon nitride as a metal-free catalyst for the removal of aniline

Mesoporous carbon nitride (MCN) was used for the first time as a thermal catalyst for the removal of aniline. While bulk carbon nitride (BCN) and mesoporous silica (MCM-41) did not show any catalytic activities, the MCN showed aniline removal (33%) at 398 K. It was revealed that the much higher acti...
