Speaker Biography:
Liane M. Rossi holds a BS degree in Chemical Engineering (UFRGS, Brazil, 1994) and a PhD degree in Chemistry (UFSC, Brazil, 2001). After postdoctoral research experience in Brazil and the USA, in 2004, she joined the Institute of Chemistry at the University of São Paulo (USP) and became a Full Professor in 2016. Her research interests in the field of chemistry and catalysis include novel approaches for the synthesis of supported metal nanoparticles with controlled size, morphology and surface properties, advanced in situ and operando characterisation techniques, new reactivity patterns at metal-ligands interfaces, bimetallic and hybrid catalysts, and the concepts of green chemistry for selective transformations. The main catalytic processes currently under study are selective hydrogenations and oxidations, including CO2 capture and conversion. She currently serves as Coordinator of the CCU Program at the Research Centre for Gas Innovation (RCGI), sponsored by FAPESP/SHELL/USP (São Paulo, Brazil). She is the author or co-author of more than 130 papers published in indexed peer-reviewed scientific journals. She is an Associate Editor at ACS Sustainable Chemistry and Catalysis and an Editorial Advisory Board Member at ACS Catalysis (American Chemical Society) and Chemistry Select (ChemPubSoc and Wiley). She is a member of the Brazilian Chemical Society (SBQ), Brazilian Catalysis Society (SBCAT), and American Chemical Society (ACS).
Presentation Abstract:
Reversing climate change is one of the major challenges faced by humankind, and its resolution is far from being consensual, as it requires dramatic changes in energy sector and governmental policies. The correlation between global warming and greenhouse gases has been well established; however, greenhouse gas emissions have grown exponentially despite the several climate change treaties. The carbon capture, utilization, and storage (CCUS) concept has received increasing attention worldwide. From the point of view of carbon dioxide utilization, there are several opportunities and challenges. The catalytic conversion of CO2 into C2+ hydrocarbons, olefins, or alcohols seems to be considered the most promising strategy. However, the most straightforward obtained chemicals are usually the C1 products, such as CO via the reverse water–gas shift (RWGS) reaction, CH4 via Sabatier or methanation reaction, CH3OH via selective hydrogenation. The hydrogenation of CO2 through RWGS to form CO and water is an equilibrium-limited endothermic reaction favored at high temperatures, and methane is concomitantly formed over most catalysts as an undesired side product at low temperatures (< 600 °C). Selectivity, green H2 supply, and energy consumption remain essential issues. The catalytic hydrogenation of CO2 into CO has been described as an important strategy for syngas production and as an intermediary pathway in several two-step gas-to-liquid processes. Methanol (CH3OH) is one of the most promising platform molecules obtainable from CO2, as it can be considered an H2 carrier or integrated with several upgrade processes to olefins or aromatics. Until now, the only successful commercial experience regarding CO2 hydrogenation is the George Olah plant in Grindavik, Iceland. This plant produces methanol using hydrothermal and geothermal energies. Owing to the growing interest in CO2 mitigation, we will give in this presentation selected results and catalyst design strategies under development at the Research Centre for Gas Innovation at the University of São Paulo.
