Sustainable strategies to generate electricity using natural resources, such as sunlight (photovoltaic cells) and wind (wind towers), have driven a significant change in our homes terms of consumption. Herein, new alternative for green supply solar‐driven evaporators devices fabricated with hydrogels is described. The photothermal production promoted by alginate‐poly( N ‐isopropylacrylamide) (ALG‐PNIPAAm) bio‐hydrogel, modified acid‐doped conducting polymer (CP), thermal absorber component, minimize energy losses. Direct current voltage monitoring are used during the solar irradiation experiments evaluate power density hydrogel generator, whereas electrochemical impedance spectroscopy employed approach diffusion processes. Impedance measurements elucidate ion dynamics within hydrogel, directly correlating this behavior enhanced generation. Therefore, highest (64.4 μW·cm −2 ) stability (32–33 μA), over time, obtained ALG‐PNIPAAm‐PEDOT‐PSS demonstrating that hydrophilic groups (OH, SO 3 H), present CP backbone, promote capillary flow electrolyte irradiation. doped molecules facilitate fast transport thanks good balance between material hydrophilicity interconnected pores.

Reverse osmosis is a widely employed technology for the desalination of highly mineralized mine water. However, achieving zero liquid discharge (ZLD) through subsequent evaporation and crystallization resultant concentrated brine incurs significant costs energy consumption. Solar interfacial water presents promising alternative generating fresh from both seawater wastewater. Nevertheless, under high-salinity conditions, formation salt crystals on surface evaporators hinders light absorption, thus diminishing efficiency. This study introduces three-dimensional (3D) columnar sponge evaporator synthesized by crosslinking sodium carboxymethylcellulose (CMC) with polyacrylic acid (PAA) incorporating coal-based carbon (MC) materials to develop photothermal sponges (CMC10/x-MC) treatment saline The polymer was formed an esterification reaction between PAA CMC high-temperature pore size tailored adjusting dosage. engineered 3D porous structure facilitated enhanced scattering within its pores, thereby boosting absorption conversion efficiency incorporated carbon. CMC10/x-MC-based achieved rate up 3.72 kg·m-2·h-1 in brines, demonstrating superior performance. Collectively, based CMC10/x-MC solar-driven solution wastewater offers viable pathway addressing challenges associated ZLD processes.
