报道了气溶胶辅助一锅法合成具有高加氢活性的介孔结构（Co）Mo/SiO2催化剂。这种催化剂形成的蒸发 * 诱导自组装机制能够优化各组分之间的相互作用，从而调节活性物质的定位。高活性可能与活性相的原始形态以及其结构中相关缺陷的产生有关。由于喷雾干燥的介孔CoMo/SiO2催化剂的加氢活性优于经典浸渍催化剂，因此气溶胶路线似乎是工业规模制备新型高效烃类催化剂的有前途的方法。
One‐pot aerosol‐assisted synthesis of mesostructured (Co)Mo/SiO2 catalysts with high hydrogenation activity is reported. The evaporation*induced self‐assembly mechanism of the formation of such catalysts enables optimized interactions between each component, resulting in the tuning of localization of the active species. The high activity is probably associated with the original morphology of the active phase as well as the creation of relevant defects in its structure. Since spray‐dried mesoporous CoMo/SiO2 catalysts outperform the hydrogenation activity of classical impregnated catalysts, aerosol route appears to be a promising way for the industrial‐scale preparation of new highly efficient hydrocarbons catalysts.
