CERVOXY COLL. International audience. A growing interest is currently directed to find an efficient NO and CO2 gas carriers for biomedical applications. The gas adsorption properties of sodium- (Na-X) and copper- (Cu-X) containing FAU nanozeolites toward nitric oxide and carbon dioxide were studied. The materials were fully characterised by XRD, TEM, ICP, DLS and in-situ FTIR. The as-prepared Na-X showed higher gas adsorption ability towards carbon dioxide, whereas the ion-exchanged Cu-X was more efficient adsorbent with regards to nitric oxide. In addition, the cytotoxicity tests disclosed that both nanozeolites have no toxicity making them suitable for further tests in biomedical field as gas transporters.
