Mesoporous manganese oxide, cobalt oxide, and hybrid Mn-Co oxide were synthesized using an inverse surfactant micelle method. The synthesized materials were monodispersed nanoparticle aggregates with connected and well defined intra-particle voids. An increase in the pore and crystallite size with increase in calcination temperature was observed with TEM, SEM, p-XRD, and N₂-sorption. These mesoporous metal oxides were employed in the selective oxidation of styrene using tert-butyl hydrogen peroxide as an oxidant. Higher selectivity towards styrene oxide was achieved using manganese oxide followed by cobalt oxide while the hybrid oxide showed the lowest selectivity towards styrene oxide. The catalytic activities of the compared catalysts were decreasing in the order of Mn-Co_350 (66.6 h⁻¹) > MnO₂_350 (47.4 h⁻¹) > Co₃O₄_350 (35.6 h⁻¹). The catalytic activities and selectivity profiles under various reaction conditions such as solvent type, catalyst amount, styrene to TBHP ratio and temperature are discussed. The catalytic recyclability of metal oxides showed that they are stable, and the structure of the catalyst was retained.

使用逆表面活性剂胶束法合成了介孔锰氧化物，钴氧化物和锰-钴杂化物。合成的材料是单分散的纳米粒子聚集体，具有连接的和定义明确的粒子内空隙。通过TEM，SEM，p-XRD和N ₂吸附观察到随着煅烧温度的增加，孔和微晶尺寸增加。这些中孔金属氧化物被用于叔酸对苯乙烯的选择性氧化-丁基过氧化氢作为氧化剂。使用氧化锰，然后使用氧化钴，可以获得更高的对苯乙烯氧化物的选择性，而杂化氧化物显示出对苯乙烯氧化物的最低选择性。所比较的催化剂的催化活性以Mn-Co_350（66.6 h ^-1）> MnO ₂ _350（47.4 h ^-1）> Co ₃ O ₄ _350（35.6 h ^-1）的顺序降低。讨论了在各种反应条件下的催化活性和选择性分布，例如溶剂类型，催化剂用量，苯乙烯与TBHP的比例和温度。金属氧化物的催化循环性表明它们是稳定的，并且保留了催化剂的结构。
