Dr. Lou is Associate Chair of the Department of Materials Science and NanoEngineering. He obtained his B.E. and M.S. degrees in Materials Science and Engineering from Tsinghua University and Ohio State University, respectively, and his Ph.D. degree from the Department of Mechanical Engineering and Aerospace Engineering and Princeton Materials Institute at Princeton University. He then did his postdoctoral research in the Brown/GM collaborative research center at Brown University before joining Rice University.

Research Areas

Dr. Lou's research interests include nanomaterial synthesis, nanomechanical characterization and nanodevice fabrication for energy, environment and biomedical applications.

By defect engineering of CsPbI3, a new all-inorganic perovskite material, CsPbI3:Br:InI3, is prepared. This new perovskite retains the same bandgap as CsPbI3, while the intrinsic defect concentration has been largely suppressed. Moreover, it can be prepared under extremely high humidity atmosphere. By completely eliminating the labile and expensive components in traditional PSCs, the all-inorganic PSCs exhibit high photovoltaic performances.

A real integrated device consisting of two series-connected perovskite solar cells (PSCs) and two CoP catalyst electrodes was proposed, which can be immersed into the aqueous solution directly for solar-driven water splitting. Benefiting from the low-cost and facile encapsulation technique, this artificial leaf possesses a compact structure and well-connected circuits for the process of charge carriers generation, transfer, and storage, revealing a solar-to-hydrogen efficiency of as high as 6.7%.

Subtle modification of atomic composition in two-dimensional substrate results in dramatic leap in electrochemically catalytic activity for converting nitrogen gas to ammonia: Cobalt substitute Molybdenum in 2D MoS2 turns it from inert to highly active for electrochemical ammonia synthesis.
