Synthesis of a novel nanoporous adsorbent based on grafting of Schiff-base ligand on SBA-15

The synthesis of a novel nanoporous adsorbent based on grafting of Schiff-base ligand on SBA-15 is reported. The material shows uniform nanooporous size. Characterization of the nanoporous adsorbent was carried out with powder X-ray diffraction (XRD), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). XRD and TEM analyses revealed the retention of the textural properties of SBA-15 during the grafting procedure. TEM analysis indicated the Schiff-base ligand functionalized SBA-15 possesses channels with the pore size of 10 nm. The obtained nanoporous adsorbent shows excellent thermal stability
