A facile strategy for preparing cobalt nanoparticles anchored magnetic porous carbon (Co-MPC) catalyst is proposed, which shows high catalytic activity for the reduction of nitrophenol to aminophenol, easy recovery, and superior reusability even after 5 times of reuse. This work provides a viable strategy for preparation of low-cost and high-performance catalysts from natural biomass.
The preparation of efficient, low-cost and easily recycled catalyst for the reduction of nitrophenol (NP) to corresponding aminophenol (AP) remains a challenge. Herein, we present a facile strategy for preparing cobalt nanoparticles anchored magnetic porous carbon (Co-MPC) catalyst, which involves first formation of Co(OH)(2)-crosslinked peach gum polysaccharide (Co(OH)(2)-PGP) gel and followed by carbonization treatment. As a natural macromolecule, PGP contains numerous oxygen-containing groups, which can interact Co2+ to form Co(OH)(2)-PGP gel. The resulted Co-MPC not only shows high catalytic activity for the reduction of diverse NPs to the corresponding APs, but also can be easily recovered by magnetic separation after catalytic reaction. Moreover, it also exhibits superior reusability. Even if it is reused for 5 times, it still maintains high catalytic activity. Considering the easy preparation process and superior catalytic performance of Co-MPC, this work provides a viable strategy for preparation of low-cost and high-performance catalysts from natural biomass.
