The science

Three themes. One catalytic vision.

Our research

Our research brings together three complementary controls: how energy reaches a catalytic site, how its chemical surroundings shape reactivity, and how interfaces couple different functions. Together, they guide new approaches to sustainable chemical transformations and environmental technologies.

Photonic architectures

Proving how slow photons drive chemistry

We chemically validate how slow photons enhance photoreactivity in photonic crystals, connecting the way light is managed to what a reaction actually does.

Toward better use of light in chemical transformations

Nanoelectrode superlattices

Nanoelectrodes that concentrate electric fields

Ordered nanoparticle superlattices amplify local electric fields. Combined with Pt–Ag electronic hybridization, they improve charge transfer and hydrogen-evolution catalysis.

Advancing electrocatalytic green hydrogen production

Water and reactant organization

Reshaping water to favor ammonia synthesis

Kosmotropic chemistry squeezes water’s molecular network to expel nitrogen toward the catalytic interface, offering a molecular route to improve nitrogen-to-ammonia electrofixation.

Designing the reaction environment for ammonia synthesis

Reactive surface chemistry

Activating interfaces for toxic-gas capture

Reticular chemistry activates nanoscale surfaces for reactive hydrogen sulfide capture under ambient conditions, linking surface design with environmental protection.

Capturing harmful gases through materials chemistry

Light-controlled biphasic reactions

Using light to steer biphasic reactions

We combine photothermal and plasmonic effects at liquid–liquid interfaces to enhance and steer reactions between immiscible phases.

Controlling chemical reactivity at functional interfaces

Transport, capture and regeneration

Moving hydrogel microbots for cleaner water

Magnetically driven hydrogel microbots generate local flows that draw pollutants in for capture. Self-catalyzed regeneration supports repeated use in continuous-flow treatment.

Developing reusable materials for water decontamination
