Fivedifferentsucrose/MOSFweightratioswereusedforthesynthesis of MCF. First of all, 0.2, 0.4, 0.6, 0.8, and 1.0 g of sucrose were dissolved separately in 5 g of H2O. Subsequently, 0.02, 0.04, 0.06, 0.08, and 0.10 g of H2SO4 were added respectively with stirring. Afterward, 0.2 g of MOSF was dispersed into each of the above solutions. The mixture was vigorously stirred for 30 min and the resulting white slurry was dried in oven at 100 ◦ C for 6 h and then at
