title: Highly Efficient Fenton and Enzyme-Mimetic Activities of Mixed-Phase VOxNanoflakes.
abstract: Artificial enzyme mimetics is a current research area with much interest from scientific community. Some nanomaterials have been found to possess intrinsic enzyme-mimetic activity. In this study, VOxnanoflakes with mixed-phases are synthesized via a quick and facile one-pot synthetic process and their Fenton reaction and enzyme-mimetic activities have been studied. The results show that obtained VOx is not only highly effective Fenton reagent, completely decomposing Rhodamine B (RhB) within less than 1 min, but also exhibits excellent intrinsic peroxidase-like activity as well as H2O2catalase-like activity. Our results suggest that this VOxnanomaterial can effectively mimic the enzyme cascade reaction of horseradish peroxidase (HRP). VOxnanoflakes have excellent affinity toward 3,3',5,5'-tetramethylbenzidine (TMB) for oxidation and henceforth, it can be used for the colorimetric assay of glucose and H2O2. Moreover, this study indicates that VOxnanoflakes can also be used for the efficient degradation of environmental pollutants.
