It is with great honor that I introduce myself as Xiang Wenjie. I am deeply grateful for the opportunity to pursue advanced studies in applied chemistry. As a dedicated student with a passion for learning, I am eager to continue exploring my interests and contributing to the field. I am particularly passionate about the conversion of carbon dioxide (CO2) and its implications for mitigating climate change.
The conversion of CO2 to higher-value hydrocarbons, such as C5+ (a mixture of hydrocarbons with five or more carbon atoms), represents a critical area of research with significant potential for addressing climate change and creating sustainable sources of energy. CO2 is a greenhouse gas that contributes to global warming, and finding ways to reduce its atmospheric concentration is of paramount importance. One promising approach to this challenge is the capture of CO2 from industrial processes and its conversion into useful products, such as fuels or chemicals, rather than releasing it into the atmosphere. The conversion of CO2 to C5+ hydrocarbons is particularly attractive because these hydrocarbons are valuable feedstocks for the production of high-value chemicals and transportation fuels. However, this process is challenging due to the high inertness of CO2 and the high activation barrier associated with C-C coupling.
To address these challenges, I propose a series of multifunctional Fe-based catalysts that are expected to achieve high conversion of CO2 and excellent liquid fuel selectivity, while maintaining great stability. Comprehensive spectroscopic characterization of the catalysts and controlled reaction studies will be employed to investigate the active site and reaction mechanism of the reverse water-gas shift (RWGS) and Fischer-Tropsch synthesis (FTS) reactions. Through this research, I aim to contribute to the development of sustainable and efficient processes for the conversion of CO2 into valuable hydrocarbons.
