Sulfonic acid functionalized wrinkled carbon/silica spheres (WNSC-SO3H) with primary mesopores were prepared with KCC-1 as a templat and p-toluenesulfonic acid (TsOH) as a carbon precursor and −SO3H source simultaneously. The physical and chemical properties of WS/C-SO3H were characterized by N2 adsorption, TEM, SEM, XPS, XRD, Raman spectrum, element analysis and acid−base titration techniques. WNSC-SO3H shows excellent performance in production of high carbon efuel precursors and exhibit a superior intrinsic catalytic activity compared to other commercial solid acids such as Amberlyst-15. The enhanced catalytic activity is attributed to the higher SO3H acid density, the larger and better communicating pores and the fibrous nature. 100% conversion and 91 % selectivity to target trimer was achieved and no distinct activity drop was observed after 5 recycles.
