Metal‐Free Catalytic Reduction of 4‐Nitrophenol by MOFs‐Derived N‐Doped Carbon

With the development of Metal organic frameworks (MOFs) materials, various functional carbon materials prepared using MOFs as precursors have attracted more and more attention. In this work, the N‐doped carbon nanomaterial N‐C have been synthesized by annealing of ZIF‐8. In the reduction of p‐nitrophenol which is one of the most prevalent organic pollutants, N‐C shows good activity, great stability, reusability and minimal pollution compared with some of the previously metallic catalysts. The N‐C prepared by annealing at different temperatures owns different nitrogen contents and different catalytic activity. It was found that N‐C 800 (annealed at 800 °C) shows the highest pyridine N content and the best catalytic activity, and the reaction follows the pseudo‐zero‐order kinetics.
