Resumo
In a world where catalysis is present in many chemical processes we use, the search for more sustainable processes and materials is needed. A factor that can help achieve this goal is the nano-architecture of the catalysts1. It is known that the physical properties of the catalysts, such as the particle size and the morphology, are crucial on the moment of choosing the best catalyst.\nA technique capable of produce particles of a determined compound, tuning the size and the morphology, is the Supercritical Antisolvent Precipitation (SAS)2. This process is already used to produce controlled particles of several pharmaceutical compounds, due to the improvement of the bioavailability, Moreover, a few studies dealing with the use of this technique, to produce catalysts have already been published.\nThe process uses a supercritical fluid as antisolvent for the desired compound, and in the end the obtained product is highly pure and free of solvents.\nIn our current work, we are producing particles of calcium acetate (fig.1) as a precursor of calcium oxide. The particles size was optimized in function of the experimental conditions (pressure, temperature, flow rate and concentration) and characterized by different techniques such as XRD, FT-IR and SEM.
