Salt-resistant MXene-charge gradient hydrogel evaporator with boosted water transport for efficient photothermal desalination – China
Highlights
- We introduce an efficient vXene-charge gradient hydrogel (MCGH) evaporator using the Donnan effect for salt rejection.
- 2D MXene films harvest sunlight effectively, converting light energy into heat for water evaporation in desalination.
- This solar steam generator uses an ion pumping effect and gradient porous structure for high osmotic pressure and salt barrier.
