Sahil Garg received his B.Tech. degree in Chemical Engineering from Indian Institute of Technology Gandhinagar (IITGN), India in 2012. Following that he worked as a graduate engineer at Hindustan Zinc Ltd, Udaipur, India for one year. In 2014, he moved to Malaysia to pursue his MS degree in Chemical Engineering from Universiti Teknologi PETRONAS. His master research includes investigating amino-acid salt solutions as solvent for CO2 capture.  Currently, he is a senior PhD student working with the Innovation Centre for Sustainable Steel and HBIS group at the University of Queensland (Australia). His research focuses on the development of electrolytes and electrochemical process for CO2 conversion and utilization.

Research Project

Title: Optimizing catalyst-electrolyte interactions for enhanced electrochemical CO2 reduction.

Advisors: Dr Tom Rufford, Prof Geoff Wang, and Dr Mengran Li

Brief Summary of project (please provide details in accessible non-specialist language) (max 350 words)

With the continuous rise in global energy demands and deleterious effects of global warming, the development of sustainable energy supply and a CO2-neutral economy has become an importance. Therefore, there is a growing interest in technologies that consume CO2 and transform it into value-added products. Renewable-powered electrochemical CO2 conversion could potentially offer a sustainable route to produce different commodity chemicals and fuels such as formic acid, CO, CH4, C2H4, ethanol, etc. Due to the inert nature of CO2, energy is required to convert the CO2 into useful products. Even though catalysts are important to lower the activation barrier to reduce CO2, equally important is the surrounding catalyst environment which can shift away from optimal operating conditions due to reaction-driven changes during CO2 reduction. My aim of my thesis is to understand the catalyst-electrolyte interactions and use that knowledge to further enhance the performance of the catalyst.
