A facile synthesis of novel ZnO structures and their applications in photocatalysis

ZnO semiconductors obtained by slip casting: Application and reuse in photocatalysis

“…17 Some of the reasons why this oxide is of great interest for application in photocatalysis are its characteristics such as physical and chemical stability, high oxidative capacity, low cost, high availability, and low toxicity. 18 ZnO properties are sensitive to defects that have localized and/or delocalized metastable energy levels in the wide band gap. 19 Despite a lot of research related to the interaction of ZnO defects with light, the phenomena is not well understood due to the nature of these defects, which strongly depends on the material's architecture, the synthesis method and the dimension.…”

“…Zinc oxide is a semiconductor with easy crystallization, an amphoteric character 16 and a hexagonal crystalline structure, known as wurtzite 17 . Some of the reasons why this oxide is of great interest for application in photocatalysis are its characteristics such as physical and chemical stability, high oxidative capacity, low cost, high availability, and low toxicity 18 …”

Template‐free synthesis of hierarchical zinc oxide with improved photocatalytic properties

“…For comparision, without a photocatalyst, a MB solution was irradiated under the same condition. It can be found from figure a that under UV irradiation for 50 minutes, the degradation of blank experiment can be negligible and 76.2%, 96.6%, 97.0% and 94.3% of MB has been degraded in the presence of S1, S2, S3,and S4, respectively, meaning that except S1, all other hierarchical zinc oxide hold more prominent photocatalytic performance compared with previous reports . Hence, it can be infered that the relatively low degradation property of the S1 may be resulted owing its large particle dimension, inferior crystallinity, and wide band gap.…”

Effect of exopolysaccharides on photocatalytic activity of ZnO nanoparticles

“…5b shows the linear plots of ln(C/C 0 ) for the photodegradation of MB with different NPs concentrations. The slops indicate the photodegradation rate constants and it can be seen that the [31] synthesized wurtzite ZnO with special morphologies such as nanoparticles, nano wires, dandelion-like, peanut-like, and micro spheres and he found dandelion-like ZnO had a highest efficiency of 96.2%. In another study nano disks had the best photocatalytic performance among the other morphologies [32].…”
