Project Grant 2604021

The National Science Foundation Division of Chemistry awarded the University of Wyoming $299,078 on August 15, 2026, under the Mathematical and Physical Sciences program (CFDA 47.049) to support collaborative research on metal nanoparticle nucleation and growth on doped ceria oxide.

The project, led by Professor Jing Zhou at the University of Wyoming in collaboration with Professor Ye Xu at Louisiana State University, investigates how substitutional doping of ceria (CeO₂) affects the formation and stability of supported metal nanoparticles through scanning tunneling microscopy and computational modeling. Metal nanoparticles on oxide supports are used in heterogeneous catalysis, electronic devices, and gas sensing, but conventional synthesis methods produce particles that lose adhesion under high temperature and reactive chemical exposure. The research seeks to develop more stable nanoparticle anchoring through dopant substitution, enabling scientists to design improved materials for chemical manufacturing and advanced devices. The project involves graduate and undergraduate students in interdisciplinary work spanning chemistry, materials science, and computational modeling.

Performance of work occurs in Laramie, Wyoming, with the period of performance running through July 31, 2029. The award is a project grant assistance type.
