Water harvesting from the atmosphere using adsorption-based technology holds great promise to solve water scarcity in arid regions. Birnessite (i.e., a layered structure MnO2) can store water molecularly between its layers, providing a path for water adsorption. This work investigates the water sorption characteristic of birnessite from both thermodynamic and kinetic perspectives. The water
