Evidence for the adsorption of CO 2 on rGO foams under quasi-real reaction conditions emplying NAP-XPS

This work present the experimental evidence of CO2 adsorption on pyrolytic reduce graphene oxide (rGO) foams, and characterized using Raman spectroscopy and high-resolution transmission electron microscopy (HR-TEM). Surface analysis revealed approximately 10% oxidation in r-GO foam. XPS analysis was performed under various conditions, including UHV and RT, oxidation at 750K, and CO 2 adsorption monitoring. The efficiency of r-GO in CO 2 adsorption-desorption was assessed through temperature and mass quadrupole (RGA). NAP-XPS enabled in-situ CO 2 adsorption monitoring on r-GO foams, underscoring its potential for mitigating gaseous pollutants and elucidating adsorption-desorption mechanisms.
