Catalytic and Conductive Framework Materials
About Prof. Xu Zhengtao and His Team
After BS (1996) at Peking University, Xu had a plan for organic chemistry, but ended up with a PhD from Cornell on coordination networks (MOFs). After postdoc at IBM and faculty appointments at George Washington University—as life would have it— Xu started anew in Hong Kong (2005), became a professor in 2015, and relocated to òòò½Íøin 2022. Our work at IMRE/A*STAR carries forth the interest in catalytic and (super)conductive frameworks. Xu also enjoy Tolstoy, Schopenhauer and other classics.
Our team members will be able to closely integrate molecular design/synthesis and the study of porous framework materials (MOF, COF and open cage compounds), in order to open broad new horizons in materials science. We are spearheading three forefront directions in open framework materials: 1) crystalline carbon frameworks (CCMs); 2) sulfur-functionalized metal-organic frameworks (SMOFs); 3) superconductive coordination polymers. In these three areas, the key properties of stability and reactivity are organically united in the open framework medium, such that the powerful sulfur functions and highly conjugated graphene motifs are driving deep innovations across catalysis, semiconductors, sensors, heavy metal removal, energy conversion/storage and superprotonic conductor and superconductor technologies.

Superconducting coordination polymers
- The soft sulfur donors bond with Co2+/Ni2+ to afford 2D sheets for charge transport, while the interlayer metal-carboxylate domain is more ionic and mediates the transition into the superconductive state.
