Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>ZnO rhombic sheets consisting of small particles with a size range of 150–250 nm have been prepared successfully using zinc glycerolate as a template through calcining at 600 °C. The crystallinity of the small particle plays an important role toward highly efficient photocatalysis. The sheet consisting of regular ZnO particles with fewer surface defects revealed enhanced photocatalysis compared with that constructed from small ZnO nanoparticles. Monodisperse Ag₂O nanoparticles were deposited on the rhombic sheet. Highly efficient photocatalysis was observed after Ag₂O nanoparticle decoration under ultraviolet and visible‐light irradiation for degradation of methyl orange (MO) and 2, 4‐dichlorophenol (2, 4‐DCP). The results of photocatalysis investigations demonstrated that the ZnO rhombic sheets with Ag₂O/ZnO molar ratio of 1:6 had great activity for decomposing MO and 2, 4‐DCP. Ag₂O/ZnO rhombic sheets are favorable for the separation of the photocatalyst, which is important for applications.</p> </abstract>
