Keywords: , ,

Substituted phenols are important industrial products and ubiquitous in aquatic environment. Their environmental toxicity and resistance against biodegradability make them a persistent pollutant and major environmental hazard. The wide spread use of these contaminants have posed many health problems1-5 and hence, substantial amount of work was done to degrade these contaminants into less toxic byproducts. Nanoparticles are known for their high surface to volume ratio that enabled them to have better catalytic reactivity as compared to their bulk counterparts.6,7 Treatment of organic contaminants with nanoparticles of zero-valent metals,6 alloys8-18 or their oxides19-26 is upcoming field for environmental remediation.27 Most of these procedures require some necessary requirements to be fulfilled like presence of some specific solvent28,29 additives30-32 or external source like UV,22,25,33,34 ultrasound,30 day light,35 microwave36 etc. or combination of these.37-39 Some of these procedures are long, tedious and costly as well.33,40
