Natural marble was successfully applied in integrated CO2 capture and utilisation for selectively producing valuable CO. The cheap easy-accessible dust is proven to have a high capacity of (9.4 mmol g−1) be active converting the captured into CO (> 85% conversion at 650 °C) with almost 100% selectivity. Furthermore, stone material exhibits impressive cycle stability (0.036 g−1 decrease per cycle). This report demonstrates that carbon emission control can realised over straightforward process using robust materials, representing an attractive technology cost-effective low-carbon development.

CO2 adsorbents comprising various alkaline sorption active phases supported on mesoporous Al2O3 were prepared. The materials tested regarding their adsorption behavior in the mid-temperature range, i.e., around 300 °C, as well characterized via XRD, N2 physisorption, CO2-TPD and TEM. It was found that Na2O phase (originated following NaNO3 impregnation) led to highest capacity due presence of CO2-philic interfacial Al–O––Na+ sites, optimum load shown be 12 wt % (0.22 Na/Al molar ratio). Additional prepared by dispersing over different metal oxide supports (ZrO2, TiO2, CeO2 SiO2), showing an inferior performance than Na2O/Al2O3. kinetics thermodynamics also investigated at temperatures, best-performing Na2O/Al2O3 material is exothermic follows Avrami model, while tests under varying partial pressures revealed Langmuir isotherm best fits data. Lastly, multiple adsorption–desorption cycles 500 respectively. maintain its with no detrimental effects nanostructure, porosity surface basic thereby rendering it suitable a reversible chemisorbent or support for preparation dual-function materials.
