Herein we report a green mechanochemical synthesis with low energy input of dual-function materials for integrated CO2 capture and dry reforming of methane. The materials produced syngas during the CH4 step (up to 0.6 mmol g−1 CO and 7.7 mmol g−1 H2) and CO during the CO2 step (up to 3.1 mmol g−1) via the reverse Boudouard reaction due to the carbon produced from CH4 cracking.
