Yu, who is from Yunnan, China, received his bachelor’s degree in Material Science and Engineering from University of Chinese Academy of Sciences. Supervised by Prof. Peidong Yang, Yu is currently pursuing his Ph.D. in Materials Science and Engineering at UC Berkeley. His research centers on converting CO2, a greenhouse gas, into valuable chemicals and fuels through electrochemical means. This research direction bears immense potential for sustainable and renewable energy development, reducing the emitted CO2, and lessening reliance on fossil fuels—an essential response to today’s climate change. To unlock groundbreaking insights, Yu employs state-of-the-art operando characterization techniques to investigate the interactions within the microenvironment along the CO2 conversion pathway, which holds great significance for advancing the catalyst design.
