SO3H-functionalized hollow mesoporous carbon sphere (HMCS-SO3H) was successfully synthesized via a facile strategy using inexpensive resins as precursor in combination with metal oxide template. By the one-step thermal treatment with sulfuric acid, it simultaneously achieved the formation of hollow spherical structure and sulfonation functionalization. HMCS-SO3H catalyst possessed superior mesoporosity, uniform sphere morphology and high acidity, which endowed it excellently catalytic property for esterification of oleic acid. In addition, HMCS-SO3H exhibited prominent stability and reusability.
