ABSTRACT=In this work, for the first time, novel Sc-MOF@SiO2 core/ shell nanostructures have been synthesized under optimal conditions of ultrasonic assisted microwave routes. The final products showed small particle size distribution with homogeneous morphology (SEM results), high thermal stability (TG curve), high surface area (BET adsorption/desorption techniques) and significant porosity (BJH method). the final nanostructure of Sc-MOF@SiO2 core/ shell with such distinct properties was as a new compound for H2S adsorption. the was used with the systematic investigation based on 2K-1 factorial design showed high performance adsorption about 5 mmol/g for these novel adsorbents, the optimal experimental conditions included pressure: 1.5 bar, time contact: 20 min and temperature: 20 °C. This study and its results promise a green future for potential controlling the gas pollutant.
