Yanhao Ren's research focuses on the synchrotron-based characterisation of battery cathode materials and single-atom CO₂RR catalysts. His work has included the use of synchrotron X-ray diffraction to monitor structural evolution, lattice changes, and phase transitions during electrochemical cycling. He has also used X-ray absorption spectroscopy to examine local coordination environments and electronic states, together with pair distribution function analysis to study short-range structural features beyond the average crystal structure. During his research, he had the opportunity to conduct experiments at DESY Synchrotron Radiation Facility in Germany and SOLEIL Synchrotron Radiation Facility in France and to collaborate with the Shanghai Synchrotron Radiation Facility, which has allowed him to gain first-hand experience with synchrotron experiments. This autumn, he will begin his PhD studies at the University of Texas at Austin in the US, where he will further pursue research on the application of advanced synchrotron characterisation techniques to energy materials.
