The present invention relates to a method for the in situ synthesis of of MOFs (metal organic frameworks), COFs (covalent organic frameworks), and ZIFs (Zeolitic imidazolate framework), onto and within different types of porous substrates, and their applications. The present invention provides a unique and easy to utilize method by which a number of MOFs, COFs and ZIFs can be synthesized directly onto and within a porous substrate with high performance efficiency ensuring higher grammage in formation of adsorbent product onto and within the substrate.

Method for in-situ synthesis of metal organic frameworks (MOFs), covalent organic frameworks (COFs) and zeolite imidazolate frameworks (ZIFs), and applications thereof

A water based double surfacted ferrofluid having magnetite nanoparticles (2-18 nm) coated with primary and secondary surfactants is synthesized. On the other hand, an aqueous dispersion of functionalized MWCNT (diameter=14-18 &#x3bc;m, length=1.6-2.5 &#x3bc;m) is prepared by acid treatment. A hybrid solutions in different v/v ratios yielded stable dispersions having both nanoparticles and nanotubes in itself behave as one system. The synthesized hybrid fluid show magnetic response and self-sustained homogeneity of in presence of magnetic field. In addition, the hybrid fluids exhibits a long term sedimentation and magnetic stability which enables one to use them for various applications like MRI, EMI shielding, energy conversion etc.
