Work History and research background:
Postdoctoral research associate Department of Chemistry University of Virginia 2016 – present Project: well-defined nanocrystal catalysts for energy conversion. o Largely enhanced the electrocatalytic alcohol oxidation activity by tuning the interfacial structure of Co2P/Pd/Au core/shell nanorods, which demonstrates with, thus far, the highest ethanol oxidation activity of 10.2 A/mgPrecious metals.
o Established a generalized synthetic strategy for well-defined brookite-phase TiO2 nanorods with tunable transition metal dopants and doping ratio.
o Clearly elucidated the phase evolution from PbS to Pb using in situ synchrotron radiation X-ray diffraction, which recorded a close to 100% Faradaic efficiency for CO2 to formate conversion and high mass activity of 74.9 mA/mgPb.
o Significantly enhanced the oxygen reduction activity and lowered the material cost of Pt-based electrocatalysts with the rationally designed Co2P/Pt core/shell nanorods, with the mass activity doubling the DOE targets. o Identified the role of solution pH and the active H species during the electrochemical water decontaminations, guiding the future catalyst design for electrochemical water treatment. o Responsible for the lab set-up and new students training; lead five graduate and six undergraduate students
(totally) in exploring room temperature water splitting, low-temperature methane oxidation, N2 and CO2 reduction.
o Successfully helped the lab to win four awarded grants from federal and state government funding agencies. o Guest lecturer at University of Virginia in courses: Nanomaterials: Synthesis, Properties, and Applications; Chemistry for Energy Future; Applied Physics-Energy. Postdoctoral research associate Chemical Sciences Division Oak Ridge National Laboratory 2012 – 2016 Project: fundamental understandings of the role of fluid-solid interfaces in energy storage and energy conversion process.
o Clarified the mechanism of oxygen reduction reaction on carbon-based materials and clearly differentiated the roles of carbon functionality and nitrogen functionality on carbon-based catalysts; for the first time, identified the role of pore texture of carbon-based catalysts in electrochemistry, guiding the future carbon-based catalyst design and fabrication.
o Achieved over 90% CO2 to CO electrochemical reduction with the rationally design Bi nanocrystal electrocatalysts. o Designed more efficient and environmental-benign approaches to make ultrahigh surface area carbons from carbonated beverages and biomass compounds.
Graduate research assistant Department of Chemical Engineering Michigan Technological University 2010 – 2012
Project: mono- or bi-metallic catalysts for energy conversion and storage, and biomass refinery. o Well-trained in the fabrication and operation of proton-exchange membrane and anion-exchange membrane fuel cells.
o Demonstrated anion-exchange membrane fuel cell with low cost biorenewable alcohol fuels; significantly boost up its energy performance with well-defined Pt-, Pd-, Au- based mono- and bi-metallic nanocrystal anode catalysts. o Realized the cogeneration of both electricity and valuable chemicals from biomass-derived polyols in the anion- exchange membrane fuel cells.
o Established the potential controlled electrochemical conversion of biomass-derived polyols into value-added chemicals.
