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.

本课题合成了基于介孔硅胶的新型多相催化剂Janus，并对其进行了表征，考察了其在三相固-液气相反应中的应用。我们认为介孔Janus粒子在固-液-气混合物中的应用特别有趣，因为由于气相和液体之间的高密度差异，在这里永远不会形成稳定的乳状液状混合物。因此，更重要的是在催化活性中心附近获得尽可能高的气体分子浓度，这是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的。所有反应伙伴的短扩散路径是这种体系的另一个优点。
