Efficient and Reusable Iron-Zinc Oxide Catalyst for Oxidative Desulfurization of Model Fuel

In this study, Fe-ZnO catalyst synthesized via modified sol–gel technique with different Fe doping ratio (2, 3, and 5) wt% was explored for oxidative desulfurization (ODS) of model fuel. The sol-gel technique was adopted without the use of surfactants. The catalysts were characterized by several mea...
