New catalyst synthesis techniques, including green materials, are extensively studied for heterogeneous photocatalytic advanced oxidation processes (AOPs) on spotlight of sustainable development. Deep eutectic solvents (DESs) started to be used in this field as environmentally friendly alternative ionic liquids (ILs). During the synthesis, DESs can act stabilizers, capping agents, structure directing templates, hydrolyzing etching intercalators, and latent supramolecular catalysts. Importantly, have exhibited ability significantly influence morphology, functionalization properties (confirmed both classic UV lamps light emitting diode (LED)), band-gap modification. positive effect was proved a variety metal oxides, metalorganic (MO) complexes doped MXene (MAX phase DES environment), inorganic-organic hybrids, carbo-catalysts. Substantial enhancements were obtained modification materials like TiO2, ZnO, MnO2, iron ceria CdS, bismuth based photocatalysts biochar In aspect, particular role confirmed nanamaterials form nanoparticles, nanopowders or nanosheets. Effectiveness further increased by oxidants such hydrogen peroxide, persulfates Fenton process. Effective application DES-modified catalysts degradation dyes (Rhodamine B, Reactive orange 16, Safranine, Orange II, methylene blue), pharmaceuticals antibiotics (Cefixime, Tetracycline, Oxytetracycline, Flumequine, Sulfamethaxazole), PFASs (Perfluorooctanoic acid) chromium (VI). This reveals high potential environmental engineering remediation. There still remaining significant gaps our understanding roles impacts AOPs. Furthermore, there is an absence data regarding recovery applied Addressing aspects vital economic applications. As research progresses, it essential unravel intricacies DES-mediated their broader consequences.

Abstract The rapid proliferation of internet‐connected devices has transformed our daily habits prompting a shift towards greater sustainability in renewable energy for indoor applications. Among the various technologies available obtaining conditions, Dye‐Sensitized Solar Cells (DSSCs) stand out as most promising due to their ability efficiently convert ambient light into usable electricity. This study explores how optimal matching UV‐Vis absorption spectra dyes commonly used DSSCs with emission profiles lamps allows enhanced efficiency DSSC under lighting. By testing four organic different ( L1 , Y123 S1 and TP1 ) two common sources (OSRAM 930 OSRAM 765 lamp), significant dye‐lamp correlation was demonstrated. Notably, low‐priced like characterized by easier synthetic routes an overlap spectrum, exhibited competitive efficiencies, narrowing performance gap high‐performing which require more demanding preparation approaches. highlights critical importance tailoring dye selection specific lighting environments, addressing paving way sustainable cost‐effective solutions
