What's Happening?
A recent study has introduced a novel catalyst, ZnO-Zn-MOF/bacterial nanocellulose (BNC), designed for ultra oxidative desulfurization of diesel fuel. The catalyst synthesis involves the bacterial strain Komagataeibacter hansenii KO28-05D, which undergoes genetic mutation through gamma ray irradiation to enhance BNC productivity. The eco-friendly nature of BNC biosynthesis contributes to the catalyst's environmental footprint. The ZnO-Zn-MOF/BNC composite is synthesized using a solvothermal reaction, resulting in a material that effectively removes sulfur from diesel fuel. The study highlights the catalyst's superior performance in sulfur removal compared to other materials, achieving a removal efficiency of 58.24%. The research emphasizes the role of BNC's polar and hydroxyl-rich surface in facilitating sulfur molecule interaction and enhancing desulfurization efficiency.
