A facile one-pot synthesis of CaO/CuO hollow microspheres featuring highly porous shells for enhanced CO₂ capture in a combined Ca–Cu looping process <i>via</i> a template-free synthesis approach

Abstract

The preparation of CaO/CuO composites with high performance is essential for combined Ca–Cu looping process, where the exothermic reduction of CuO with methane is used <italic>in situ</italic> to calcine CaCO₃.
