To address the CO2 accumulation in atmosphere, various initiatives have been proposed, among which capture and utilization (CCU) is regarded as an appealing strategy to reconcile carbon emission resource utilization. Especially, integrated (ICCU), i.e. performing in-situ conversion can circumvent energy-intensive desorption step thus facilitate establishing step- energy-efficient process, rendering at mild conditions particularly low pressure due substantial activation upon uptake. However, not simple add-up of these two processes. Its successful implementation relies on harmonization reagents, substrates corresponding catalysts.
