2021年10月1日 · Hexagonal WO 3 irreversible transformation to Li 2 WO 4 can be experimentally demonstrated via in situ HRTEM in the deep lithiation process including the initial activation of the lithium metal, the wetting of a single WO 3 nanowire and the migration of lithium ions into WO 3, and the restructuring of hexagonal WO 3.

In order to investigate the effect of photointercalation on photoelectrochemical properties, two types of WO3-based photoanodes, bulk and exfoliated have been prepared and investigated. An...

2015年6月18日 · In this study, we report a facile method to embed gold catalyst on highly porous WO 3 nanowires. The high-porosity nanowire structures of Au-embedded WO 3 were synthesized by using porous...

Narrow bandgap tungsten oxide (WO3−x) nanoparticles have been synthesized by single-step plasma discharge in deionized water between two vertically pointed tungsten electrodes.

The X-ray diffraction patterns and Raman spectra corroborate the formation of different crystal phases viz., monoclinic (m-WO3), orthorhombic (o-WO3) and hexagonal (h-WO3).

4 天之前 · The response value (Ra/Rg) of WO3/Ag@CeO2 sensor to 10 ppm xylene gas reaches 32.13 at the operating temperature of 160 °C. Additionally, the sensor displays an exceptional response to even trace amounts of xylene, as low as parts per billion (ppb). ... TEM, HRTEM, selective electron diffraction (SAED), ...

2014年6月30日 · In this work, we report a one-step template-free hydrothermal route to synthesize monoclinic WO 3 nanoplates through a topochemical conversion process from H 2 WO 4 nanoplates precursors. The visible-light-driven photocatalytic activity of the as-prepared WO3 nanoplates is evaluated and compared with a commercial WO 3.

Here, we report a low-cost and simple hydrothermal synthesis of a WO 3 -based hexagonal–monoclinic phase junction heterostructure with excellent HER performances, evidenced by detailed structural and electrochemical characterization. A comprehensive description of the HER mechanism at the interface of the phase junction is also provided. 2.
