Research at a glance
Three capabilities, one experimental loop.
Reaction engineering defines performance, spectroscopy resolves the working structure, and data-guided methods help choose what to test next.
02Working structure
Spectroscopic Characterization
XAS, in situ DRIFTS, photoelectron spectroscopy, Raman, microscopy, and complementary methods connect local structure and surface species with catalytic behavior.

Data-Guided & Machine Learning
Experimental datasets, chemically informed candidate review, validation, and descriptor feedback turn reaction and characterization evidence into the next catalyst or experiment.
Dataset → candidate → validation → feedbackSelected highlights
Evidence across design, mechanism, and discovery.
Representative examples of how catalyst design is connected to measurement and interpretation.
Ensemble control
Controlling Pt ensembles with phosphorus
Phosphorus decreased the effective Pt ensemble size, suppressing structure-sensitive hydrogenolysis and improving propylene selectivity in propane dehydrogenation.
