Metal Nanoparticles as Recyclable Catalysts for Reductive Transformation of Profenofos Pesticide in Aqueous Media

Reduction of organophosphate group of pesticides catalyzed by bimetallic nickel cobalt nanoparticles (NiCoNPs) in presence of sodium borohydride has been discussed. An easy, simple, quick and economically feasible approach has been made to synthesize the good ordered structures of hetero nanoparticles. These air stable nanoclusters could be synthesized most economically using nickel sulphate and cobalt sulphate salts with tetrabutyl ammonium bromide as surfactant and sodium borohydride as reducing reagent. The nanoparticles were used to degrade pesticides like profenofos and imidacloprid under ambient conditions in aqueous media. The concentrations of Profenofos (PFF) were quantified by measuring the absorption intensities at λmax288 nm after treatment with KOH solution. The nickel nanocolloids in common organic solvents were found to be good catalysts for the reductive transformation of Profenofos but suffer considerable deactivation during recycling steps. The bimetallic group of particles containing cobalt and nickel however can be easily recovered and recycled three-four times without loss of catalytic activity. The bimetallic nanoclusters having average particle size 90-120 nm can degrade organophosphate group of pesticides within 120 minutes which is much less compared to photodegradation of such similar pesticides as reported in literatures. The study can become a protocol for waste water management with environmental benefits, strengthening the need of green chemistry in industrial projects.
