This work addresses the dual challenges of seawater purification and converting low-grade waste heat into electricity, both which are crucial for sustainable resource management. It presents a combined approach that solves problems using self-fabricated device. The device generates temperature gradient through efficient photothermal conversion by placing thermoelectric hydrogels on top hydrogel. Poly(vinyl alcohol) (PVA) is used as matrix hydrogel was selected its biocompatibility ease processing. In order to enhance solar-driven water evaporation efficiency, ball-milled dititanium trioxide (Ti2O3) nanoparticles carbon nanotubes (CNTs) incorporated within PVA matrix. enables rate high 3.22 kg m–2 h–1. Additionally, also serves gels, soaked with K3[Fe(CN)6]/K4[Fe(CN)6] redox pair solution exploit thermogalvanic acid (TGC) effect. arrangement voltage generation reactions at hot cold ends. obtained excellent properties can be characterized ionic Seebeck coefficient (Si) 1.48 mV K–1 power density 9.6 mW after nine were connected in series. As result, this dual-functional simultaneously effectively purifies electricity. Outdoor testing shows daily production 9.2 stable 130 from hydrogels. advances energy technologies opens new avenues innovative applications renewable energy.

Abstract Bifunctional MOF-303 (Al) exhibits promising catalytic activity for the Biginelli reaction. However, its intrinsic microporosity may hinder reactant and product diffusion reducing efficiency. Introducing defects is crucial enhancing performance. In this work, defect-rich was prepared by grinding hydrothermally synthesized into a fine powder. The resulting material thoroughly characterized exhibited excellent performance in solvent-free synthesis of diverse dihydropyrimidinones under moderate reaction conditions, achieving yields between 94% over 99%. Moreover, catalyst successfully recycled five cycles with minimal loss. structures obtained products were confirmed IR, ¹H NMR, melting point analysis. simple preparation method using commercially inexpensive reagents, high mild recyclability highlight potential as an efficient sustainable

Abstract A solar‐thermal reduced graphene oxide/octadecane (RGO/oct) phase‐change foam is fabricated by the interfacial assembly of an air‐in‐oil‐in‐water three‐phase emulsion and subsequent chemical reduction oxide (GO) for day‐night evaporation desalination. The GO sheets assemble at water‐oct interfaces in presence amphiphilic alkyl glycoside while air pores are generated inside hydrophobic oct component under stirring, leading to GO/oct/air microspheres. During molding, chemically with ascorbic acid, resultant RGO/oct/air microspheres closed constitute RGO/oct foam. suppress heat conduction bulk water, prevents loss environment, hence enhancing localization capability exhibits a high rate 4.29 kg m −2 h −1 1‐sun irradiation. Interestingly, can release latent absence solar light irradiation, enabling water nighttime 2.30 . overlap molding allows rearrangement salt concentration gradients, exhibiting satisfactory resistance during stable brine 25 wt.% NaCl 10 h.
