In this project, novel heterogeneous Janus catalysts based on mesoporous silica gel are synthesised, characterised and investigated for their application in three-phase solid-liquid gas reactions. We consider the application of mesoporous Janus particles in solid-liquid-gas mixtures to be particularly interesting because a stable, emulsion-like mixture can never form here due to the high density differences between the gas phase and the liquid phase. It is therefore all the more important to achieve the highest possible concentration of gas molecules in the vicinity of the catalytically active centres, which we want to achieve through the specific surface functionalisation and the intrinsically high specific surface of the mesoporous silica gels. Short diffusion paths of all reaction partners are another advantage of such systems.

在这个项目中，新型多相Janus催化剂的基础上介孔硅胶的合成，表征和研究其在三相固-液-气反应中的应用。我们认为介孔Janus颗粒在固-液-气混合物中的应用是特别有趣的，因为由于气相和液相之间的高密度差异，在这里永远不会形成稳定的乳液状混合物。因此，在催化活性中心附近实现气体分子的最高可能浓度是更加重要的，我们希望通过介孔硅胶的比表面官能化和固有的高比表面来实现。所有反应伙伴的短扩散路径是这种系统的另一个优点。
