Education
Professional Experience 2002 - Stay in Padua at the laboratories of Prof. Sandro Campestrini working to the optimization of heterogeneous oxidations in compressed carbon dioxide. 2003 - Stay in Montpellier working with Prof. Joël J.E. Moreau and Dr Michel Wong Chi Man on chiral catalytic materials under the provisions of the CNR’s Short term mobility program 2002/2003.
Current Research Interest After several years working at the chemistry of natural products, in 1999 she started to work on heterogeneous catalysis applied to the sustainable production of fine-chemicals. Her research aims to the achievement of a reaction system applicable at industrial level for the selective oxidation of organics avoiding the use of high toxic and polluting chromium and manganese salts and using oxygen and ideally air as primary oxidant in an “green” reaction medium. Rosaria’s research work mainly concerns the design, preparation and characterization of hybrid sol-gel doped catalysts and the use of supercritical carbon dioxide as alternative reaction medium. Hybrid organic-inorganic sol-gel materials posses very intriguing properties being the solid matrix hybrid at molecular level. The entrapment of a catalytic species inside the pore network of organic modified silicas (ormosils) gives rise to very active catalysts suitable for the oxidative conversion of a large range of organic alcohols using O2 at atmospheric pressure as primary oxidant. The use of this new, versatile aerobic catalysts in scCO2 has led to an 'entirely clean' aerobic process for the oxidation of alcohols without any organic solvents. She has worked on the selective oxidation of sugars into uronates by a patented system based on the entrapment of TEMPO radicals in pure and modified silica xerogels and co-authored the first example of one-pot conversion of glycerine into valuable mesoxalic acid. Rosaria also works with Joël Moreau and Michel Wong at the development of a novel catalyst for the asymmetric dihydroxylation of olefins.
