This guarantees both theirproximity for enhanced interaction and, at the same time, sufficient separationavoiding mutual harm. Before the acutal design of a usually very complex hybridcatalyst, it is essential to study and understand the impact of structural characteristicson catalytic activities of each catalytically active constituent separately. This studythus focuses on a comprehensive structure-activity analysis of the component withina highly customizable TiO2-SiO2 material, which produces H2O2 photocatalytically.The tailorable design of the hybrid material is achieved through the utilization of thespray-drying process. The H2O2 productivity of the obtained so-called TiO2-SiO2 supraparticles is demonstrated in both a batch anda flow reactor, marking a crucial step toward their future application as hybrid catalysts in photoassisted cascade reactions.enSupraparticlesphotocatalysttitaniahydrogen peroxide productionmicrofluidic reactorflow chemistrycascade reaction500 Naturwissenschaften und Mathematik::540 Chemie500 Naturwissenschaften und Mathematik::530 Physikjournal article
