Catalysis
Electrolyzer and Membranes
Engineering Nano-structures
Atomic Layer Deposition — Nano-materials — Graphene — Functionalization
Engineering interfaces at the nanometer scale allows for improved activity and stability. We design nano-structures using an in-house modified Atomic Layer Deposition (ALD) process and a metal/alloy spark generator to tailor properties (such as metal regeneration, ferroelectricity, etc.) and to enable electrons to directly promote active catalytic sites. Materials of interest include perovskite films and reducible mixed oxide films supporting metal nanoparticles, alloys, single atoms, and more.
Electrotuneable Dynamic Catalysts
Catalytic capacitors — Dynamic Oscillations — Millisecond Operations
Direct electron modulation on catalytic sites allows for promotion in activity and selectivity with the possibility to utilize energy from greener sources. We aim to study the kinetic properties of different catalytic systems, to understand the effects of charge modulation, and to improve catalytic performance for important industrial applications. Other modes of perturbation will also be explored in the future. The current goal is to build a robust understanding of the effects of charge on different catalytic systems, to enable reaction engineering, and ultimately, to build a better catalytic system.
