An enhanced capture structure is disclosed, including a sorbent structure having a COsorbent material. The capture structure also includes a plurality of barriers extending outward from the sorbent structure, each sized and positioned such that as an airflow passes along the sorbent structure, a high pressure region forms proximate the sorbent structure on a first side of the barrier facing into the airflow and a low pressure region forms proximate the sorbent structure on a second side of the barrier facing away from the airflow. The barriers on one side of the sorbent structure are staggered with respect to barriers on the other side such that a plurality of high and low pressure regions are formed, each high pressure region being formed opposite a low pressure region on the other side of the structure, creating a pressure differential that promotes COmass transfer into the sorbent material via convection.
