Abstract
Many of the harmful pollutants such as organic compounds in water are generated diseases in human beings and contaminated our environment. Many industries produce these chemical waste and release into our environment. These chemical compounds created the many problems for the human and environment due the increasing of diseases and contamination of natural water bodies. Therefore, it is not possible to remove 100 percent of these toxic chemicals from the water bodies. We need the green technology which can remove 100 percent of toxic chemicals from the environment. A photocatalyst is defined as "a substance able to produce, by absorption of ultraviolet (UV), visible, or infrared radiation, chemical transformations of the reaction partners, repeatedly coming with them into intermediate chemical interactions and regenerating its chemical composition after each cycle of such interactions. Due to its exceptional qualities like nontoxicity, high photocatalytic degradation ability, and superior thermal and chemical stabilities, TiO2 based photocatalysts demonstrate excellent absorption behavior toward organic molecules in wastewater. Significant environmental contaminants known as chlorophenols have caused major issues for both aquatic and terrestrial life. Therefore, to protect our ecosystem for future generations, their eradication requires urgent, efficient, and cutting-edge solutions. This paper includes a thorough investigation of the uses of chlorophenols, their negative effects, and their photocatalytic breakdown
