Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures
Advanced Science, EarlyView.Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...
