Direct Air Capture is a promising climate mitigation technology, but its deployment is limited by high energy demand. This study improves the energy efficiency and sustainability of liquid-based Direct Air Capture by integrating catalytic solvent regeneration and hybrid solvents with a low-temperature membrane vacuum regeneration process. Iron-sulfated zirconia catalysts supported on alumina and silica are synthesized and evaluated, with silica exhibiting superior catalytic performance.
