Abstract: A major public health concern in many developing countries, including Nigeria, is the quality of their water supply. Everything a live entity does depends on water, a fundamental component of the biosphere. To ensure that water is safe for industrial and home use, it must be treated before consumption. However, phenolic compounds are found in our water bodies due to the polluted wastewater from industrial, agricultural, and home activities. Nature also has a role in their occurrence. These substances are poisonous and can cause long-term harm to both humans and animals. This paper reviewed research on the photodegradation of phenol utilizing nanoparticles in water treatment. This provides additional information and facts on cost-effective methods of treating wastewater and mineralizing phenol into valuable chemicals.

Keywords: Photocatalysis, Phenol, Pollutants, Wastewater, Metal ions.

I. INTRODUCTION

Water supply contamination is a growing issue. Most current treatment methods are efficient at cleaning water, but they only move toxins from one medium to another or produce waste that needs to be cleaned up and disposed of [1]. Effective techniques for converting resistant pollutants into less hazardous chemicals or complete mineralization are required. Transferring impurities from one water phase to another is not the best solution. More long-lasting solutions are offered by destructive oxidation processes [2].
Recent developments in oxidation technology have shown promise for treating wastewater and water. Photodegradation is an effective method used to treat toxic and bio-resistant pollutants [3]. The highly reactive hydroxyl radical is the oxidant involved in oxidizing organic molecules. The production of hydroxyl radicals can be accomplished in various ways, each requiring the employment of an oxidant and an activating system [4].
