Summary
In the last decades, chemists become more concerned about the impact of the chemistry and\nindustrial chemistry in the world. These concerning’s were translated in a search for more\nsustainable processes, methods and products in different grounds: Environmental, Social and\nEconomic 1. Many future scenarios and solutions have been proposed, and in many of them,\ncatalysts appear with an important role to play. To achieve these future scenarios, some challenges\nare need to be faced in the catalysis field, for example the nanoarchitecture of the catalysts 2.\nIn this work, the proposal is to produce particles of catalysts using the Supercritical Anti Solvent\nmicronization (SAS) process. SAS is already been used in the production of particles of compounds\nto the pharmaceutical or food industry, as well as to obtain some precursors of catalysts 3,4. The SAS\ntechnique enables the production of particles controlling the size of the particle, the size\ndistribution and the morphology, according with the experimental conditions.\nThis method to obtain the catalysts particles is particularly interesting for heterogeneous catalysis,\nbut in the homogeneous catalysts perspective, it can be used to recover the catalyst from the\nreaction medium.
