RESEARCH INTEREST

Advanced structural elucidation

The core interest of our research group lies on using three primary advanced synchrotron X-ray techniques to elucidate the crystal structures at atomistic resolution.

Synchrotron X-ray powder diffraction (SXRD)

Distinctive adsorption structures found in zeolites with the MFI topology. Angewandte Chemie 132.3 (2020): 1109-1113. & PCCP 2020.


X-ray pair distribution function (XPDF)

Probing local structural distortion of Li and B in the octahedral institutials in nano-Pd by using in situ XPDF and PDFgui.  Journal of the American Chemical Society 141.50 (2019): 19616-19624.


Extended X-ray absorption fine structure (EXAFS)

By combining SXRD with EXAFS, the structure of ultra-stable single-site Cu anchored on the -NH2 moiety of UiO-66-NH2 has been revealed. ChemComm 2020: submitted.

Catalysis

We aim to use our expertise in structural elucidation to unveil many unsolved puzzles in catalytic science.

Biomass catalysis

Photocatalysis

We focus on using photocatalysis to solve various environmental challenges, including the utilisation of CO2 and the decomposition of organic pollutants from wastewater. Under Review.
