We demonstrate current self-complianced and self-rectifying bipolar resistive switching in an Ag-electroded Na-doped ZnO nanowire device. The resistive switching is controlled by the formation and rupture of an Ag nanoisland chain on the surface along the Na-doped ZnO nanowire. Na-doping plays important roles in both the self-compliance and self-rectifying properties.

In this work, photocatalytic performance is divulged in the ternary CuO-Ag-ZnO nanowire synthesized via a two-step approach. The decoration of Ag and CuO nanostructures onto surface ZnO nanowires was simply carried out by using plasma electrolytic oxidation method short time. structure, size, morphology, optical properties as-prepared samples were characterized X-ray diffraction, field-emission...

Metal–organic frameworks (MOFs) have been widely used in various fields, including gas storage, separation, sensors, and catalysis, owing to their excellent performance. In this study, a zinc-based MOF [MIL-125(Zn)] was successfully synthesized using the solvothermal method, Ag-doped ZnO (Ag/ZnO) prepared by pyrolyzing Ag/MIL-125(Zn). The fabricated Ag/ZnO as photocatalyst for rhodamine (RhB) d...

Conductive and transparent multilayer thin films consisting of three alternating layers (TiO2/Ag/SiO2, TAS) have been fabricated for applications as transparent conducting oxides. Metal oxide and metal layers were prepared by electron-beam evaporation with ion-assisted deposition, and the optical and electrical properties of the resulting films as well as their energy bounding characteristics a...

Hydrogen peroxide (H2O2) is an important chemical as it environmentally friendly oxidant for organic synthesis and environmental remediation well a promising candidate the liquid fuel. Photocatalytic generation of H2O2 sustainable, many efforts have been put into development new catalysts to gain high yields. In this investigation, Au/ZnO, Ag/ZnO Au-Ag/ZnO were prepared by simultaneous impregna...

In the pursuit of high injection current diode nanodevices, entire one-dimensional (1D) ZnO coaxial nanostructures with p-n homojunctions is one of the ideal structures. In this study, we synthesized entire 1D ZnO-based coaxial homojunction diodes with p-type Ag-doped ZnO (SZO) nanostructure shells covering n-type Ga-doped ZnO (GZO) nanopagoda (NPG) cores by a metal-organic chemical vapor depos...

A simple and efficient self-approach strategy was used to apply ultrasensitivity and self-revive ZnO-Ag hybrid surface-enhanced Raman scattering (SERS) sensors for the highly sensitive and selective detection of explosive TNT in both solution and vapour conditions. The good ultrasensitive sensing performance is a result of the abundant Raman hot spots, which were spontaneously formed in a rever...

Water borne pathogens present a threat to human health and their disinfection from water poses a challenge, prompting search for newer methods and newer materials. Disinfection of Gram-negative bacterium Escherichia coli and Gram-positive coccal bacterium Staphylococcus aureus in aqueous matrix was achieved within 60 and 90 minutes respectively at 350C using solarphotocatalysis mediated by sono...

Either metal/metal or metal/non-metal co-doping is one of the most effective methods to modulate visible emission ZnO. In this paper, ZnO, aluminum-doped ZnO (Al-ZnO), aluminum and silver co-doped (Al/Ag-ZnO), nitrogen (Al/N-ZnO) are deposited. Combining substitution zinc ions using Al and/or Ag doping oxygen N expected introduce more interstitial vacancy defects related light in films. The res...
