wastewater treatment includes adsorption, heterogeneous photocatalysts along with
enhancement of reactive oxygen generation. Photocatalytic process has been widely
explored owing to its flexible design and simple operation. Thus, the use of MOFs as
photocatalysts has been investigated for removal of pollutants owing to their inherent properties such as high surface area, environmental stability, easy preparation
and tunable structure. The plethora of literature reported that a variety of morphological characteristics can be accomplished, which strongly depends on the method
of synthesis, and thus have various effects on the removal of pollutants. In this
chapter, we have demonstrated that different types of MOF have an influence on the
photodegradation efficiency of organic dyes. Henceforth, the synthesis of variety of
MOFs and their composites have been studied for the photocatalytic degradation of
dyes such as phenol, MB, MO, MG and RhB from wastewater. Overall, these MOFs
composites display improved photocatalytic efficiency towards dyes degradation.
Therefore, data in this chapter provides an insight into MOF based materials for
potential use as economically valuable photocatalysts for the degradation of organic
dyes from wastewater.
