چکیده
Ni(SO4)0.3(OH)1.4 nanobelts were synthesized by a facile hydrothermal method. Humidity sensors based on Ni(SO4)0.3(OH)1.4 nanobelts were fabricated and exhibited high sensitivity and a fast response. They also showed good long-term stability. The high performance could be related to the high surface-to-volume ratio of nanobelts and the chemical composition of Ni(SO4)0.3(OH)1.4.

متن کاملLa ( OH ) 3 and La 2 O 3 Nanobelts — Synthesis and Physical Properties
Since the discovery of nanobelts of semiconducting oxides in 2001, planar structures of nanobelts have been intensively researched because they present a good system for examining dimensionally confined and structurally well-defined physical and chemical phenomena. Nanobelts, with a rectangular cross section and well-defined faceted surfaces, enable the observation of unique optical-confinement...
متن کاملEnhancement of ethanol vapor sensing of TiO2 nanobelts by surface engineering.
TiO(2) nanobelts were prepared by a hydrothermal process, and the structures were manipulated by surface engineering, including surface coarsening by an acid-corrosion procedure and formation of Ag-TiO(2) heterostuctures on TiO(2) nanobelts surface by photoreduction. Their performance in the detection of ethanol vapor was then examined and compared by electrical conductivity measurements at var...

The transformation characterization of Ni(OH)2/NiOOH in Ni-Pt films was investigated using an electrochemical quartz crystal microbalance (EQCM) in an alkaline electrolyte under various experiment conditions. The Ni-Pt films were prepared by electro-deposition on gold-coated quartz crystal chips. When cyclic voltammetry (CV) was performed continually, the OH ions diffused into the Ni-Pt film to...
