| Abstract Scope |
Copper looping (CuL) technology represents a promising approach for direct air capture (DAC) of CO₂, leveraging copper-based oxygen carriers to enable efficient CO₂ separation from ultra-dilute atmospheric streams. This mini-review explores the underlying redox chemistry of copper oxides cycling between Cu and CuO phases, focusing on their high oxygen transfer capacity and favorable regeneration temperatures compared to conventional sorbents. Recent advances in material synthesis, including nano-structuring and doping, have improved the stability and CO₂ uptake kinetics critical for cyclic operation. The review further discusses reactor designs tailored for copper looping DAC, challenges related to sorbent deactivation, and energy integration strategies with renewable sources to minimize carbon footprint. Potential applications in carbon-negative technologies and synergy with chemical looping combustion are also examined. Copper looping thus offers a scalable and energy-efficient platform for ambient CO₂ removal, contributing to global climate mitigation efforts. |
