Interests:

The Hu research group at Yale designs and demonstrates photo-synthetic electrochemical devices, in particular, those splitting water into renewable hydrogen fuels and oxygen under sunlight. Our group employs a complementary set of modeling, materials synthesis, electrochemical and spectroscopic techniques to discover new phenomena and interrogate materials/electrolyte interfaces at meso-to-nano-scale.

We are currently investigating the following areas:

Modeling-inspired design principles towards efficient and stable photoelectrochemical devices
Thermo-chemical CO₂ conversion and mitigation
Semiconductor photocatalyst model study
