PNNL develops metal-free peptoid assemblies for carbon mineralization
PNNL reported on October 14 on crystalline peptoid nanosheets and nanotubes that mimic enzymes without metal cofactors. Histidine-inspired catalytic groups promoted conversion of carbon dioxide into bicarbonate and carbonate-mineral formation in the presence of calcium.

Published: · Updated:
The source does not state the event date; the period shown is the source review period.
Carbon-13 nuclear magnetic resonance measurements showed accelerated mineralization, with nanosheets eliminating the induction period before mineral formation. The assemblies displayed thermal and chemical stability. This is materials and catalysis research; the source reports no commercial capture plant, emissions-removal volume or industrial cost.
