Calcium-looping reforming of methane realizes in situ …

Abstract Closing the anthropogenic carbon cycle is one important strategy to coat climate change, and requires the chemistry to effectively coine CO 2 capture with its conversion. Here, we propose a novel in situ CO 2 utilization concept, calcium-looping reforming of methane, to realize the capture and conversion of CO 2 in one integrated chemical process.
