Disposing of wastewater contaminated with dyes into the environment results in water pollution, which endangers aquatic life and leads to severe health issues for all living species. Zinc oxide-assisted heterogeneous photocatalysis is a significant approach treating dyes. However, its wide energy gap, activated only by UV light, high electron hole pairs recombination rate constrain photocatalytic activities. This review emphasizes impact doping ZnO transition metals non-metals on dye degradation. Both significantly enhances ZnO's photoactivity reducing band shifting absorption edge visible spectrum, producing more oxygen vacancies crystal defects, decreasing conduction electrons valence holes, boosting surface area. The characteristic nanostructures contingent upon their physiological characteristics, including morphology, particle size. It also includes data from literature regarding some dyes' potential degradation pathways mechanisms using ZnO-based photocatalysts.

Doped semiconductor heterostructures have superior properties compared to their components. In this study, we observed the synthesis of Cu-doped ZnO/Ag/CuO heterostructure with presence charge transfer and visible light-harvesting resulting from doping heterojunction. The porous were prepared using bottom-up combustion (BUC) approach. This method generated by eliminating gaseous by-products. X-ray diffraction (XRD) optimization revealed that ideal conditions included 1.00 g polyvinyl alcohol (PVA), a temperature 50 °C, 1 hour calcination time. Introducing copper (Cu) into zinc oxide (ZnO) lattice caused high-angle shift in XRD pattern peaks. High-resolution transmission electron microscopy (HRTEM) images patterns confirmed formation (c-zac) heterostructures. Elemental mapping analysis even surface distribution Ag metal. c-zac exhibited optoelectrical single ZnO. demonstrated improved methylene blue (MB) dye degradation potential (

Abstract Piezoelectric materials offer great promise due to their ability generate electric fields under mechanical stress, producing surface charges that drive otherwise kinetically sluggish redox reactions. The strained surfaces of these provide a unique advantage in controlling product selectivity and enabling reaction pathways are unattainable with conventional methods. This perspective highlights advancements, challenges, the future potential piezoelectric synthetic organic chemistry, focus on designing optimized for piezocatalyzed synthesis. Piezocatalysis is industrially relevant because its operational simplicity, mild, gram scale synthesis reusable catalysts, minimal solvent use, air tolerant conditions. It involves cycles facilitate one electron events without requiring light exposure or electrical bias. Despite significant progress, many fundamental aspects yet be fully understood. One example correlation between piezoelectricity catalytic activity, which not always linear, as demonstrated by comparison tetragonal cubic BaTiO₃. While BaTiO₃ piezoelectric, it shows excellent activity certain reactions such arylation, dicarbonylation, cyclization mechanochemical conditions comparable Considering all aspects, this aims stimulate discussion advance promising field right direction.
