Carbon Dots-Integrated Boron Nitride for NaOCl-Based Oxidative Desulfurization of fuel oil

The Sulfur compounds in fuel oils are the primary cause of environmental pollution if these compounds are not removed from fuel oil it causes serious issues to ecosystem like acid rain, global warming, and different toxic diseases to both life on earth an aquatic. It is inevitable to eliminate these substances to conserve environment for this purpose different techniques are used for desulfurization of fuel oils. The most emerging and effective method for this selective removal we used Oxidative desulfurization (ODS) as a frontrunner for fuel purification. This study covers the preparation of carbon dots (CDs) from banana peels via hydrothermal treatment and boron nitride (BN) through pyrolysis. The CDs-BNs composite catalyst was then developed and after going through characterization CFE-SEM, EDX BET, XRD, and FT-IR confirming its structural integrity and surface properties. The catalyst’s efficiency was assessed in ODS of dibenzothiophene (DBT) under optimal conditions: 40°C temperature, NaOCl/Sulfur = 1 mL, catalyst/DBT solution ratio of 0.2 g/15 mL, and a 25-minute reaction time. Achieving 100% conversion of DBT, CDs-BNs demonstrates the potential in developing sustainable and high-performance systems for ultra-clean fuel oils.
