Hu, Shu - Yale University - Department of Chemical & Environmental Engineering

个人简介

Ph.D., Stanford University B.S., Tsinghua University

研究领域

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
