Fig. 1. The SEM images of (a) bulk-Mn(TCPP)OAc, (b) nano-Mn(TCPP)OAc and (c) [Mn(TCPP)OAc@MWCNT]. These data confirm that simple sonication can makes uniform na- noparticle of metalloporphyrins from the bulky sample. Moreover, the structure of carbon nanotubes after porphyrin incorporation was checked by SEM image (Fig. 1, c) which remained unchanged and no bulky particles or aggregated manganese porphyrins is detectable onto the surface of multi walled carbon nanotube. Based on the results, it seems that sonication or anchoring of porphyrins onto the surface of solid support limited the tendency of amphiphilic molecules of Mn (TCPP)OAc towards aggregation. Supported catalyst [Mn(TCPP)OAc@ MWCNT] was also fully characterized by various standard methods (See Supporting information, S2). The structure and morphology of catalysts were studied by SEM
