Abstract Pure and different percentages (0.25, 0.5, 1.0, 2.5%) of silver (Ag) doped hydroxyapatites (Hap) were synthesized employing the wet chemical precipitation method. The samples characterized with aid X‐ray diffraction (phase analysis, crystallographic characterization, crystal size calculation using Scherrer equation models), scanning electron microscopy, optical bandgap energy. Hap containing 0.25% Ag showed better photocatalytic activity in various dye concentrations, catalyst doses, pH.

Environmental Science and Pollution Research, Год журнала: 2023, Номер 30(54), С. 114779 - 114821

Опубликована: Ноя. 3, 2023

Abstract Water pollution stands as a pressing global environmental concern, elevating the significance of innovative, dependable, and sustainable solutions. This study represents an extensive review use photocatalytic zinc oxide nanoparticles (ZnO NPs) for removal emerging pollutants from water wastewater. The examines ZnO NPs’ different preparation methods, including physical, chemical, green synthesis, emphasizes on advantages, disadvantages, factors, investigation methods structural morphological properties. NPs demonstrate remarkable properties photocatalysts; however, their small dimensions pose issue, leading to potential post-use losses. A strategy overcome this challenge is scaling up NP matrices enhanced stability efficiency. paper introduces novel composites, by incorporating supports like carbon clay that serve photocatalysts in In essence, research underscores urgency finding efficient, eco-friendly solutions wastewater highlights high efficiencies obtained when using synthesis photocatalyst. Future should be developed cost–benefit analysis regarding treatment processes, value-added product regeneration Graphical
