Efficient adsorption desulfurization via encapsulation of CeO nanoparticles in hierarchical porous HKUST-1.

Thiophene-like sulfides present in fuel oil release sulfur oxides (SO) during combustion, which pose significant risks for both environmental sustainability and public health. Adsorption desulfurization (ADS) has garnered considerable attention because of its mild operating conditions, low production costs, and minimal impact on the octane number of fuels. Metal-organic frameworks used as desulfurizing adsorbents provide several advantages, including a high specific surface area and easily adjustable structures.
