Title : Developed halophytes encapsulated PANI for highly efficient solar steam generation
Abstract:
To ensure the uppermost performance of Solar Steam Generation (SSG), which is a promising strategy responsible for providing sustainable sea water supply, an efficient photothermal diversion process is needed. Herein, halophytes which are salt-tolerant plants that grow in water with high salinity was used as salt rejection absorber. This by comparing three different parts of halophyte plants residues and showing their ability differences to resist salinity, these parts showed gradual rates of water evaporation. A high rate of evaporation 1.15 kg m-2 h-1 with 79.01 % conversion efficiency is produced in some parts naturally without any modification. To increase water evaporation rate, a photoabsorber substance was fabricated by means of encapsulation mechanism using polyaniline as a promising photothermal material and halophyte plants residues as salt resistant material resulting an outstanding evaporation rate of 1.89 kg. m-2.h-1 high conversion efficiency. Accordingly, our system is considered as an eco-friendly method, which reduces the negative environmental effects of desalination processes and can lower water production costs by using Solar desalination technology.
