Yonghua Du joined NSLS-II in 2019 as the lead beamline scientist of the Tender Energy X-ray Absorption Spectroscopy (TES) beamline. Before that he worked for 10 years at the Institute of Chemical and Engineering Sciences (ICES), Agency for Science, Technology and Research (A*STAR) of Singapore. During this period, Yonghua built a world-class in situ XAFS beamline at the Singapore Synchrotron Light Sources, called XAFCA. He also built strong collaborations with researchers working on catalysts and batteries, which led to great scientific impact.

After joining NSLS-II, Yonghua mainly focus on three aspects:

Develop advanced autonomous beamline techniques enhanced by AI/ML methods

TES beamline upgrades

 Develop collaborations in catalyst, battery, and geoscience

Research Highlights

  • Developed a general method for automatic beamline optimization based on AI/ML and extended this method to multiple beamlines & light sources
  • Discovered the first stable Ni(OH)2 nanoribbon phase. It has been proven to be one of the best oxygen evolution reaction catalysts. Moreover, it also shows excellent methanol oxidation reaction performance, which is expected to replace Pt in the fuel cell. This material will play an important role in the future of clean energy.
  • Developed a novel method based on operando XAFS technique to study the surface storage mechanism of batteries. An important application is to study a TiO2(B) Li-ion battery. The surface storage effect can contribute 90% more extra capacity of the battery. This is a general method, which can be applied to study other battery system.
  • Developed the highest spatial resolution EXAFS data analysis method, which is three time more precise than conventional methods and approaching the resolution limit of the uncertainty principle.
