Abstract

Manganese-based octahedral molecular sieves (OMS-2) of rod-like, fibrous-like, dendritic-like, and nest-like morphologies were synthesized by solid-state reaction, reflux, and hydrothermal methods, respectively. The materials were characterized and tested for liquid-phase oxidation of p-chlorotoluene to p-chlorobenzaldehyde. Over nest-like OMS-2, p-chlorotoluene conversion was significantly higher than that of the others. The differences in catalytic performance are attributed to the effects of composition and structure. The high activity of nest-like is due to the high concentration of oxygen adspecies and good mobility of oxygen species, whereas the poor performance of dendritic-like is due to the presence of chromium.
