Three-dimensional
porous carbon-based materials from metal–organic
frameworks (MOFs) have been proven useful in structural mechanical
and catalytic applications due to the high specific surface area and
excellent electron transport property. However, introducing and loading
of metal catalytic sites on MOF-derived porous carbon-based materials
always involves complex multistep synthetic processes and unwarrantable
catalyst sites with high catalytic activity. Here, we have developed
a facile Mo-doping-assisted strategy to construct a highly active
nanorod with Ni-based catalyst nanoparticles from a MOF (MCF-61).
Thanks to the assistance of Mo-doping to restrain the migration and
aggregation of elemental Ni, the obtained Mo-doped Ni-based catalyst
(MNC) exhibited excellent catalytic activity in the solution-phase
hydrogenation of nitrophenols compared to those reported in other
studies. Moreover, the role of molecular structures of nitrophenols
on their reduction in MNC has been revealed by quantum chemical calculations.
The unique structure, high catalytic activity, good cycle stability,
and ease of separation individualize MNC with great potential in diverse
applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
