Fabrication of advanced cellulose-based devices for solar desalination: A review

Materials derived from cellulose have attracted considerable attention as affordable substrates for solar desalination, contributing to the solution of the worldwide water crisis. These substances allow for exact control of structural features and improve light absorption in photothermal processes, promoting specific interactions between light scattering and reflection within their porous structure. Moreover, cellulose can be readily transformed into nano- and microporous forms, which enhances water transportation due to its inherent three-dimensional properties. This review examines the design and utilization of cellulose-based solar evaporators for desalination purposes. With benefits such as biocompatibility, environmental friendliness, economic viability, renewable nature, sustainability, and versatility for diverse designs, cellulose-derived materials are set to play a vital role in addressing global water issues.
