Epoxidation of styrene under heterogeneous catalyzed conditions provides environmentally friendly routes to produce styrene oxide, an important synthetic intermediate for synthesis of perfumes, epoxy resins, plasticizers, drugs, sweeteners and fine chemicals. The present review explores epoxidation of styrene under heterogeneous catalysed conditions using a variety of catalysts such as metal nanoparticles, metal oxides (of group 12 and 13 metals, transition metals, rare earth metals), transition metals and complexes, polyoxometallates, microporous and mesoporous materials (zeolites, modified zeolites, organic/inorganic porous hybrid materials, porous metal oxides, SBA 15) and polymers using hydrogen peroxide (H2O2), tert‐butyl hydroperoxide (TBHP), air or oxygen as oxidants.The use of salen based transition metal complexes and of chiral porphyrins as catalysts in asymmetric epoxidation of styrene is also reviewed. The reaction mechanism studies of most of these reactions suggest an intermediate formation of a reactive metal‐oxygen species, by interactions between the catalyst and oxidant.

“…16 Carbon materials stand out as possible catalytic supports due to their favorable proprieties such as high surface area and porosity. 17–19 The carbonization of resins can easily be used to prepare porous carbon which has hierarchical porous and high surface areas. Mo 2 C is easily dispersed on this support.…”

A molybdenum carbide-carbon composite (β-Mo2C/C) is prepared by carbonization of an anionic resin with molybdate. The β-Mo2C/C is characterized by X-ray diffraction, N2 physisorption, scanning electron microscopy, and transmission electron microscopy. Characterization indicates that the sample shows a hierarchically microporous, mesoporous, and macroporous structure, and has a large surface area. The nanosized β-Mo2C crystals are highly dispersed in the carbon-based sample. The β-Mo2C/C composite shows high catalytic activity in the hydrogenation of naphthalene to tetralin.
