Abstract

Abstract : The present work reports construction of Co-MOFs with amide based bispyrazole ligand and different carboxylic acids which have potential applications in CO2 adsorption and photocatalytic waste water treatment. Abstract : The present work reports the construction of new Co-MOFs based on an amide based bispyrazole ligand and different carboxylic acids with potential applications in the sphere of CO2 adsorption and photocatalytic waste water treatment. Four multifunctional MOFs, with a wide variety of dimensionality, porosity and surface characteristics were exploited for this purpose. The unique bis-bidentate nature of the ligand with two chelating compartments along with a semi-rigid backbone leads to some interesting chiral MOFs. Detail self-assembly studies reveals that both helicity as well as local environments around the metal centres are responsible for chirality. A detailed investigation shows the importance of these materials as chiral zeolite analogues for environmental remediation. The much improved photocatalytic degradation of a representative toxic dye molecule highlights the advantages of MOFs over the usual metal oxide based semiconductors as remediation materials. Furthermore, MOFs with an ability to capture CO2 gas, offer a solution to environmental pollutions.
