Highly efficient nickel catalyst for CO2 methanation
Scientific Achievement
Researchers developed a highly efficient and stable catalyst with ultralow metal loading for CO2 methanation by using single atoms of Ni and Co on a ceria support through organometallic grafting.
Significance and Impact
This type of catalyst has the potential to enhance the economic viability and scalability of CO2 methanation processes by providing a cost-effective catalyst that uses significantly less metal while maintaining high performance.
Research Details
- At the CNM, the Quantum emitter electron nanomaterial microscope (QuEEN-M) and Talos TEM were used to visualize single-atom catalysts.
- Single atom electron energy loss spectroscopy (EELS), Cathodoluminescence (CL) at the CNM were used to determine chemical valence states of individual atoms.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
