Current Research Projects
Our group's research stays at the interface of materials synthesis and catalytic science, with an emphasis on precisely controlling composition and constitution of nanostructured particles and membranes for renewable energy conversion and storage applications. In particular, we are focusing on two avenues: 1) Tailoring the architectures and functionality of nanostructured materials to enable efficient and selective catalytic reactions in biorefinenery and petrochemical/fine chemical conversion; 2) Assembling nanostructured particles and membranes to provide desirable properties in fuel cells and batteries. Our overall objective is nano-engineering of advanced materials with structural elucidation, growth mechanism perception, and industrial application exploration in catalytic conversion technologies to enabling the development of green and sustainable energies. Below, you will find brief descriptions of our ongoing research projects.
