Topic : Cu (II), V (IV) and Co (II) complexes of 2-picolinic acid encapsulated in fly ash based zeolite, their characterization and catalytic activity towards hydroxylation of phenol

Abstract:Fly ash is a major residue generated from coal fired power plants. Owing to the environmental threats posed by fly ash, several attempts have been made for gainful utilization of fly ash. In this work, the possibility of synthesizing high value added products such as zeolites from fly ash has been explored. Fly ash based zeolite (FAZ) has been synthesized from fly ash by hydrothermal treatment. The formation of FAZ has been confirmed by FT-IR, XRD, TGA, SEM, XRF and BET surface area analysis. The cation exchange capacity of FAZ has been determined. Cu(II), V(IV) and Co(II) complexes of 2-picolinic acid have been encapsulated in the pores of FAZ by flexible ligand method. The zeolite encapsulated complexes were characterized by FT-IR, SEM, AAS, TGA, XRD and UV-Vis spectrophotometry. M-O stretching has been observed at 767 cm-1 for the encapsulated metal complexes. The encapsulated metal complexes thus prepared have been screened for catalytic activity using hydroxylation of phenol as a test reaction, the products identified to be hydroquinol and catechol by GC-MS. The extent of the reaction has been monitored as a function of time. A maximum conversion efficiency of 73.10% has been observed. Such heterogeneous catalysts offer the advantage of easy separation of the catalyst and reusability. .

Keywords: Fly ash zeolite, flexible ligand method, 2-picolinic acid.
