MoO 2 /biochar catalysts for oxidative desulfurization toward ultra-low sulfur diesel via carbothermal reduction of pistachio shell waste
Abstract
redox cycle produced highly electrophilic oxoperoxo-molybdenum species as primary active sites, while the graphitic biochar surface enabled π-π stacking interactions for refractory dibenzothiophene (DBT) sequestration, as revealed by FTIR and SEM characterization. Kinetic studies validated pseudo-first-order kinetics with respect to the concentration of DBT. These results demonstrate the potential of MoPSBC as a cost-effective, biomass-derived catalytic platform for advanced fuel purification, providing a scalable solution for ULSD production.
