The various aspects such as reaction, sensing material, photoelectric material, insoluble drug release obtain a wide range of applications.At present, come from MOFs precursors or
The research of the functional material of template is increasing, for example, porous carbon, metal oxide, metal/carbon and metal oxide/carbon are received
Rice material has been reported, constructed 3D metal oxides, for efficient ultracapacitor, lithium ion battery and hydrogen reduction,
Show excellent property.2014, Chaikittisilp and his team reported prepare electricity by precursor of MOFs first
Catalyst is used for the report of decomposition water, and they use class zeolite Co-MOF (zeolitic imidazolate framework-
9, ZIF-9) nanoporous Co is prepared for precursorxOy- C composite electro-catalysis OER.Because of the side of direct high temperature pyrolysis MOFs precursors
Method frequently results in framework and collapses and reunite, therefore, at present frequently with an innovative strategy be to utilize such as graphene, more walls
The nano carbon material load MOFs of CNT (multiwalled carbon nanotubes, CNTs), then pass through high temperature pyrolysis
C-base composte material elctro-catalyst is prepared, to prevent product from reuniting and improve its specific surface area.For example, 2016, Aijaz and he
Team by Co-MOF in H2The reduction of atmosphere high temperature and oxidizing roasting, have been made a kind of Co@Co3O4Nano-particle is embedded in carbon and received
The carbon polyhedron high activity oxygen-separating catalyst of the N doping of mitron grafting.Although MOFs species is various, easily prepared and transformation
For the elctro-catalyst MOFs precursors of controlled morphologies, limited amount, at present, using three-dimensional (3D) MOFs crystallites or nanocrystal before
Body prepares the research of oxygen-separating catalyst it has been reported that as far as we know, oxygen-separating catalyst is prepared based on one-dimensional MOFs nanofibers
Research have no report.
