Atomic Materials for Catalysis Research Group
Our research group works on the heterogeneous catalysis for renewable energy and sustainable chemistry, and nano/micro-scale stretchable energy storage devices for powering nano-bioelectronics and microelectronics. We aim to develop catalysts based on atomic-scale design for conversion of abundant feedstocks like C1 molecules into value-added chemicals or fuels and biomass upgrading to biofuels and hydrocarbons. We also target to enhance the fundamental understanding of electronic and geometric structure-catalysis relationship. Meanwhile we integrate materials science, chemical engineering and electrical engineering to design and fabricate nano/micro-scale flexible electrochemical energy storage devices.

Hydrogen evolution: Not living on the edge
Transition-metal dichalcogenides are appealing catalysts for H2 generation from water. They tend to rely on scarce edge sites, rather than the more abundant basal-plane sites, to drive catalysis. Now, guided by computation, H-TaS2 and H-NbS2 are proposed as highly basal-plane-active catalysts that improve with electrochemical cycling.
Doped nanotubes beat heavy metal for CO2 reduction
Avoiding the use of fossil fuels in energy production is high on the sustainability agenda and the likes of wind and solar power have come to the fore as viable alternatives. But, liquid and gas fuels are still needed for many applications. Instead of using fossil fuels, what if we could extract the greenhouse gas carbon dioxide from the atmosphere and convert it into organic fuels in a process driven by wind or solar?
Carbon dots dash toward ‘green’ recycling role
Graphene quantum dots may offer a simple way to recycle waste carbon dioxide into valuable fuel rather than release it into the atmosphere or bury it underground, according to Rice University scientists.
