In Situ Formation of WC/W2C Heterostructures on N-Doped Carbon for Deep Oxidative Desulfurization of Fuel Oil

Molecules, Journal Year: 2025, Volume and Issue: 30(3), P. 617 - 617

Published: Jan. 31, 2025

A novel tungsten-based heterojunction nanocomposite material was developed for the efficient oxidative desulfurization (ODS) of fuel oil, enabling production low-sulfur and a reduction in harmful SOx emissions. In this material, WC/W2C uniformly immobilized on porous nitrogen-doped carbon (NC) matrix structure through facile situ pyrolysis polyaniline-phosphotungstic acid (PANI/PTA) precursors. The resultant WC/W2C@NC catalyst demonstrated remarkable performance, achieving 100% removal 4000 ppm dibenzothiophene (DBT) just 15 min at 60 °C presence 0.03 g H2O2/S molar ratio 2. This exceptional activity is attributed to synergistic effects stemming from accelerated electron transfer by NC matrix, intricate network, abundant active sites. Moreover, formation around mitigated site leaching, ensuring stability, with DBT rate 97.2% maintained even after eight recycling cycles. work provides versatile scalable approach fabricating catalysts highlights potential as high-performance, durable ODS catalyst, paving way further advancements sustainable technologies.
