The distribution of ions at the air/water interface plays a decisive role in many natural processes. Several studies have reported that larger ions tend...

The concept of direct air electrolysis for hydrogen production: (a) a schematic diagram of the direct air electrolysis module with a water harvesting unit made of porous medium soaked with the hygroscopic ionic solution; (b) a schematic diagram of the cross-section of the direct air electrolysis module, showing the electrodes are isolated from the air feed, and the absorbed water are transported to the electrode by capillaries of the sponge.

In this diagram of the new system, air entering from top right passes to one of two chambers (the gray rectangular structures) containing battery electrodes that attract carbon dioxide; then the airflow is switched to the other chamber, while the accumulated carbon dioxide in the first chamber is flushed into a separate storage tank (at right); these alternating flows allow for continuous operation of the two-step process.
