Abstract

This chapter deals with degrading dyes using Metal-Organic Frameworks as a heterogeneous catalyst. Metal-Organic Frameworks (MOFs) are an excellent material for dye degradation due to their multifunctionalities, such as semiconducting properties, ease of use with controllable structures, high surface area, and enormous active sites. MOFs exhibit a promising photocatalytic activity under UV–visible light irradiation due to band gap presence. Several MOFs show an excellent reusability performance even after a few consecutive cycles. The MOFs used to degrade dyes are classified as bare MOFs (Lewis acid MOF, Brønsted Base MOF), MOFs@SiO2 , magnetic MOFs, MOF nanocomposites, ionic MOFs, bimetallic MOFs, nanoparticles doped MOFs, etc., The mechanism of dye removal and photocatalytic degradation of organic dyes using MOFs and the detailed pros and cons of these materials are discussed in detail.

Keywords: Bare MOF, Bimetallic MOF, Ionic MOF, Magnetic MOF, Nanocomposite MOF, Silica supported MOF.
