Experimental investigation of the effect of cerium oxide nanoparticles as a combustion-improving additive on biodiesel oxidative stability: mechanism

Abstract

Nano cerium oxide, a combustion-improving fuel additive, was investigated for its impact on biodiesel oxidative stability. The findings of the present study revealed for the first time that nano cerium oxide addition at the concentrations generally used to improve combustion (<100 ppm) severely reduced the oxidative stability of biodiesel.
