Abstract

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