Microwave-assisted Synthesis of Hierarchical ZnO Nanostructures and Their Photocatalytic Properties

Abstract

Abstract. Hierarchical ZnO nanostructures were fabricated via a rapid and facile microwave-assisted route with different zinc salts as reactants. The obtained hierarchical ZnO nanostructures have good crystallinity and high purity. Moreover, it was found that various zinc salts have an obvious effect on the morphologies and microstructures of the final products. Additionally, the photocatalytic activity of the obtained ZnO samples under visible-light irradiation was also evaluated by degradation of Rhodamine B (RhB).

Desarrollo de nanoestructuras de ZnO mediante anodizado electroquímico en diferentes condiciones para su aplicación en el área energética

“…So far, several dyes and organic pollutants have been studied for its photoelectrocatalytic degradation using ZnO nanostructures. Some of them are rodhamine B [119][120][121][122][123] methyl orange [71,[124][125][126], methylene blue [88,124,[127][128][129][130][131][132][133][134], congo red [133,135], resazurin [136], thiacloprid [137] and roxarsone [138]. It has been reported that differences in surface characteristics such as morphology and defects influenced photoelectrocatalytic degradation efficiency.…”
