Metal oxide nanoparticles as efficient catalysts for biodiesel production.

Currently, a lot of effort has been carried for the development of an alternate fuel to meet with the energy requirement and transportation vehicle system of the World. In this regard, one of the most promising alternates, that have been used for small scale production is "Biodiesel". Biodiesel is broadly defined as the monoalkyl ester of long chain fatty acids that can be derived from renewable sources like lipid feed stocks, vegetable oils like rape seed, coal seed, waste cooking oil, algal oil and/or any waste oil. The use of algal oil for biodiesel production produces some interesting properties due to its easy availability all around the world. [ABSTRACT FROM AUTHOR]
