Intensification of chemical processes according to the motto "faster, simpler, greener" is among the main concerns nowadays. One of the ways of intensification is the application of synergistic catalytic effects when the overall efficiency of a composite catalyst is much higher than the sum of the component activities. Here, we report on the preparation of synergistic catalytic materials by a simple and straightforward ball milling procedure. Oxidation of benzoin was selected as a model reaction to demonstrate the viability of the concept. For the V2O5-TiO2 (95 : 5) composite material, the synergistic effect is triggered by low power microwave irradiation with more than a tenfold jump in the catalytic activity in comparison to the activities of the individual components.
根据“更快、更简单、更环保”的口号，加强化学过程是当今的主要关注点之一。强化的方法之一是应用协同催化效应，当复合催化剂的整体效率远高于各个组分活性的总和时。在这里，我们报告了通过简单直接的球磨工艺制备协同催化材料的方法。苯偶姻氧化被选为模型反应，以证明该概念的可行性。对于 V2O5-TiO2（95∶5）复合材料，协同效应是由低功率微波辐射触发的，与单个组分的活性相比，催化活性提高了十倍以上。
