| Abstract | ||
| Desalination is commonly used nowadays to overcome freshwater scarcity in several regions of the world, especially those with access to brackish or saltwater. Water treatment, desalination, and power generation all depend on the transformation of solar energy into heat to produce steam. Solar steam generation (SSG) offers a promising technique to address the global water and energy crisis with minimal environmental impact. This is achieved by using black photothermal materials, which gather solar energy and convert it into thermal energy in the form of heat. This technology utilizes black nanoparticles as a light absorber, thereby improving solar energy absorption and conversion efficiency. Biomass-based materials have garnered considerable attention recently as potential ISSG substrates. This is explained by their hydrophilicity, low heat conductivity, abundance, low cost, and biocompatibility. The fabricated photoabsorber demonstrated a high efficiency of 95.7%% and an outstanding vaporization flux of 1.4 kg m-2 h-1 when exposed to one sun (1 kW m-2). Herein, this review explains how our evaporator biomass-based photothermal material (BC) performs for ISSG to generate clean water. | ||
