Pore-size engineered nanoporous silica for efficient adsorption cooling and desalination cycle

Abstract Adsorption cooling and desalination (ACD) system powered by renewable energy has been considered as a promising solution to solve interconnected global problems such as freshwater scarcity, high-cost air conditioning, CO2 emission, and global warming. In this work, a new nanoporous silica w...
