carbon architectures are attracting tremendous
interests for various promising applications due to their outstanding
electronic and mechanical properties, although it is a great challenge
to rationally devise facile and operative methodologies to engineer
their structural traits owing to complex synthetic processes. Herein,
for the first time, we fabricate two-dimensional carbon nanoribbons
via direct thermal exfoliation of one-dimensional Ni-based metal–organic
framework (MOF) nanorods, in which interconnected graphitic carbon
nanocages are self-assembled into a belt-like superstructure with
carbon-encapsulated Ni nanoparticles immobilized on the surface. Due
to the unparalleled structural superiority, the MOF-derived carbon
nanobelts exhibit excellent catalytic performances in electrocatalytic
hydrogen evolution. Importantly, the practical synthetic strategy
may trigger the rapid development of carbon-based superstructures
in many frontier fields.
