Solar steam generation is an efficient way to address global freshwater shortages. However, water evaporation suffers from either inefficient heat conduction or relies on expensive materials and complex equipment. Herein, a porous hydrogel (AC-H) with molecular meshes, micron channels, and internal gaps is fabricated and used for metal ion adsorption. AC-H exhibits excellent uptake ability and can attain the levels required by industrial water safety standards. Subsequently, the exhausted AC-H hydrogel is vulcanized in situ (AC-MS) and upcycled for solar steam generation resulting in ≈1.41 kg m −2 h −1 evaporation rate under one sun irradition, which reduces costs and converts the waste into a resource. Furthermore, a heat management strategy is developed where a cold surface of specific area is introduced between the AC-MSx and bulk water to adsorb the heat loss. When the cold area is increased, the energy in the bulk water can be extracted by the coldsurface. which enhances the water evaporation rate. Significantly, the theoretical simulations are in good agreement with the experimental results. Therefore, this research provides a novel strategy to upcycle exhausted materials for photothermal technologies and reduces the heat conduction during solar-to-thermal evaporation.

“…The mixtures of fatty acid methyl esters that are formed as a result of transesterification procedures that involve sources of biomass are called Biodiesels that contains over 80% of biofuel total production (Hazrat et al., 2021; Mofijur et al., 2021; Yin et al., 2020). Rapid lipid accumulation, year‐round of cycles harvesting opportunities, quick biomass weight doubling capacity and ease at water, sunlight and carbon (IV) oxide utilization are criteria that shows that biodiesel from third‐generation microalgae source is a representation of viable option to diesel from fossils origin (Hu et al., 2022; Yin et al., 2020; Zhang et al., 2019).…”

Present dependence on fossil sources for meeting energy demand globally is unsustainable as a result of non‐renewable and depleting supplies. Therefore, this study focuses on production and characterization of biodiesel by Chlorococcum littorale (Chlorococcum sp.) isolated from fish pond in Owode fish farm, Nigeria. Biomass concentration, lipid extraction and quantification were determined by filtration, solvent extraction and gravimetric methods. Extracted lipid was transesterified to diesel through process catalyzed by concentrated tetraoxosulphate (VI) acid. The constituents of fats in biodiesel produced were examined through chromatography of gas and spectroscopy of mass. Model prediction was used to assess physical and chemical parameters of biodiesel. The data gathered was subjected to statistical analysis. Chlorococcum sp. had biomass concentration (4.42 ± 0.02 g/L), Lipid content (67.75% and biodiesel yield (96.33%). Biodiesel had 48.3%, 29.20%, and 22.50% fatty acids that are saturated, monounsaturated and polyunsaturated, respectively. The biodiesel produced has the kinematic viscosity (2.74 mm2/s at 40°C); point of flash (245°C); point of cloud (7°C); point of pour (−2°C) and density (0.8760 g/cm3). Furthermore, the acidity level (0.44 mgKOH/g), value of saponification (186.49 mgKOH/g), value of peroxide (3.25 meq/kg), iodine content (38.27 mgI2/g) as well as the free fatty acid (1.34%), number of cetane (65.78), oxidative resistance (7.33 h), saturated factor of long chain (28.16°C), plugging point of cold filter (35.62°C) and high heating value (43.24°C) fell within required standard by international body. Thus, Chlorococcum sp. is ideal microalgae isolate for the biodiesel production. The biodiesel produced conform satisfactorily with the acceptable global standard.
