Oxidative desulfurization is an important non‑hydrogen desulfurization technology, but traditional TiO2 catalysts are subject to‌ the weak acidity and weak adsorption ability towards alkaline sulfide molecules, limited by the long reaction time for deep desulfurization. Herein, based on the principl...
