- Abstract
- The technical features of aerosol processes make them highly interesting for the continuous, large scale, and tailored production of divided nanomaterials, and in particular of advanced heterogeneous (nano)catalysts.1 In addition to the “simple” aggregation of preformed particles via spray drying, reactive aerosol processes – such as the “aerosol-assisted sol-gel” process (AASG) – allow synthesizing tailored-made catalysts with tunable surface properties, textures, compositions, surface functionalities, etc.2 The method is based on the sol-gel chemistry process, possibly coupled with the evaporation-induced self-assembly (EISA) concept.3 It allows producing micronic or submicronic, inorganic or hybrid organic-inorganic particles bearing tunable and calibrated porous structures at different scales. Here, we explain why this peculiar mode of preparation has led to high-performance solid nano-catalysts in various applications including olefin metathesis,4-6 lactate synthesis,7-10 olefin epoxidation,11 (trans)-esterification.12, 13 We will also demonstrate the concept of chemo-enzymatic heterogeneous catalysts able to run cascade reactions.14, 15 Our objective is to demonstrate the tremendous possibilities offered by the coupling between bottom up sol-gel routes and aerosol processing technologies, which will arguably represent a major route of innovation not only in the field of catalyst preparation, but also more broadly in the mushrooming nanotechnology field.
