Facile Synthesis of Zinc Indium Oxide Nanofibers Distributed with Low Content of Silver for Superior Antibacterial Activity

Abstract

Exploring new antibacterial materials is of great significance for limiting the transmission of germs and protecting human health. Although Ag and oxide nanoparticles have both been extensively used in the field of antibacterial, it is still urgently need to figure out how to combine their characteristics for sterilization. Herein, ZnO/In2O3‐Ag nanofibers are prepared with uniformly dispersed Ag through a facile method of electrospinning and subsequent sintering. The obtained nanofibers are of high purity and have diameters from 90 to 110 nm. The silver is in a zero‐valent state, which is beneficial for sterilization. The quantitative test of bacterial activity shows that the nanofibers are bactericidal for both Staphylococcus aureus and Escherichia coli, with an especially strong inhibitory effect on E. coli. At relatively low concentrations, 98% of E. coli can be killed. Herein, light is shed on exploring more complexes of oxide nanomaterials and Ag for sterilization.

Electrochemical conversion of CO2into HCOO−in a synergistic manner by a nanocomposite of Zn2SnO4/ZnO

“…As displayed by the X-ray diffraction (XRD) pattern in Fig. 1a, all the peaks closely matched the main characteristic peaks of hexagonal-phase ZnO with a P63mc(186) space group (JCPDS number: 36-1451) 27 and cubic-phase Zn 2 SnO 4 (JCPDS number: 24-1470). 28 Compared with pristine ZnO, the diffraction peaks of ZnO in Zn 2 SnO 4 /ZnO composite showed a slight shift towards a high diffraction angle (Fig.…”

Phosphorus-modified cobalt single-atom catalysts loaded on crosslinked carbon nanosheets for efficient alkaline hydrogen evolution reaction

“…Hence, exploring simple and low-cost synthesis methods while ensuring high activity and stability is of great significance for the development and application of SACs. 20 Top-down synthesis strategies, which have simple synthesis procedures and are low cost compared to their bottom-up counterparts, have been considered efficient methods to fabricate SACs. 21 In particular, high-temperature pyrolysis provides a flexible route to synthesize carbon nanomaterials with metal loadings.…”

Dopamine-coated layered Co0.85Se as an efficient bifunctional oxygen electrocatalyst

“…43 The Raman spectrum of Co 0.85 Se@NC gives a higher intensity ratio ( I D / I G = 1.04), indicating the presence of structural defects and disorder in the carbon. To further analyze the structure and composition of the bonding in the samples, 44 the surface chemical state of Co 0.85 Se@NC was evaluated by X-ray photoelectron spectroscopy (XPS). The full spectra (Fig.…”
