Surface-functionalized Hexagonal Mesoporous Silica Supported 5-(4-Carboxyphenyl)-10,15,20-triphenyl Porphyrin Manganese(III) Chloride and Their Catalytic Activity

physisorption, SEM, TEM, FTIR and thermal analysis were employed to analyse these novelheterogeneous materials. These silica supported catalysts were shown to be used for epoxidation and goodshape selectivity was observed. The effect of support structure on catalytic performance was also discussed.The catalytic activity remained when the catalysts were recycled five times. The energy changes aboutepoxidation of alkenes by NaIO
