SYNTHESIS OF ATOMICALLY DISPERSED M-N-C CATALYSTS VIA SELECTIVE METALATION
WARF: P210397US02
Inventors: Shannon Stahl, Jason Bates
The Invention
UW-Madison researchers have developed a solution-phase metalation method for increasing M loading on N-C. The N-C supports are synthesized by high-temperature pyrolysis of N, C precursor mixtures (e.g., MOF, PANI, Phen, and Mel). Macrocyclic N4 sites on the surface are metalated (e.g., CoCl2 in DMF using Bu3N to drive the deprotonation equilibrium). Basic conditions lead to strong electrostatic adsorption of cationic M species at deprotonated surface acidic moieties. A mild acetic acid wash removes these species but leaves MN4 intact. A final pyrolysis step is used to remove ligating solvent or chloride from the MN4 site, rendering it catalytically active.
Key Benefits
- Can allow for novel M-N-C materials
- Potential compatibility with any metal stable in DMF at 150 degrees
- Potential tunability of N content, configuration, and also porosity parameters
