The invention provides a preparation method for rapidly growing a
metal organic framework derivative with assistance of a
metal salt, and belongs to the technical field of nano material preparation and fuel
cell catalysis. The preparation method comprises the following steps of: firstly, adding the
metal salt and a high-molecular
polymer into an
organic solvent, stirring to obtain a
mixed solution, acquiring a metal salt / high-molecular
nanofiber membrane by adopting an electrostatic
spinning technology, and then uniformly
coating the metal salt / high-molecular
nanofiber membrane with an organic ligand solution required by the growth of the MOF; and secondly, achieving
chemical bond combination of metal ions and ligands in nanofibers through adopting a
hot pressing technology, so that the MOF material compactly and evenly grows on the
nanofiber membrane, and the MOF / nanofiber membrane is calcined under
inert gas to form the metal-embedded
nitrogen-doped
porous carbon nanofibers. According to the preparation method, solvents such as
methanol,
ethanol and water are not used in the preparation process, and the method is short in preparation time, simple in process, environment-friendly and suitable for large-scale production and has important application value in the fields of energy
catalysis and
environmental protection.
