(a) TEM image of pristine CMK-3 nanochannels; Inset, hexagonal ordered mesostructured view of CMK-3; (b) SEM image of as-synthesized CMK-3/CNTs nanocomposites, of which two particles are connected by CNTs wrapped around CMK-3; Inset, pristine CMK-3 particles; (c) TEM images of CNTs in bundles synthesized by the microwave process; Inset, electron diffraction pattern of CNTs and catalyst particles; (d) TEM images of CNTs protruding from the mesoporous nanochannels of CMK-3.
