Green, effective and trouble-free transesterification of coconut oil using NiWO4 nanoparticles under blue LED light medium

Abstract

Biodiesel production is a major requirement in environmental research to reduce the harmful effects on climate from industries and transporters. The need of biodiesel is an emerging field of study in various science techniques to improve its availability. In this present study, NiWO₄ nanoparticles were successfully prepared by using a simple precipitation method. The prepared NiWO₄ nanoparticles have to be used for the transesterification of coconut oil under visible light irradiation. The enormous amount of fatty acids present in coconut oil is the major source to replace the acid derivation to substitute the methyl group on the terminal to make the ester to produce biodiesel in a visible light medium. The NiWO₄ nanoparticles show excellent activity in transesterification, producing up to 89 % of biodiesel under a visible light medium. NiWO₄ nanoparticles are very reactive, stable, work well with visible light, have quick reaction times, are easy to recover, and can be reused many times in transesterification.
