2018年9月1日 · Transmission electron microscopy (TEM) analysis (JEOL ARM 200 probe corrected TEM, operated at 200 kV) was used to study the passivating interface of Nb 2 O 5 films on HF-treated c-Si using focused ion beam (FIB) made lamellas. Prior to FIB milling, 15 nm ITO films were deposited for protection by reactive sputtering in the DC mode at 2 mTorr ...

2008年4月3日 · In this paper we report microstructural studies by transmission electron microscopy (TEM) of magnesium hydride nanocomposites produced by ball milling. The work employed high angle annular dark field (HAADF) imaging, high resolution TEM (HRTEM), and electron energy loss spectroscopy (EELS).

2024年1月22日 · Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are the most commonly used electron microscopy methods to study the morphology of battery materials. Li et al. 47 developed orthorhombic Nb 2 O 5 nanotubes by atomic layer deposition methods using polyacrylonitrile nanofibers as a sacrificing template.

2017年8月3日 · In the present work, heterogeneous TiO 2 @Nb 2 O 5 composites, in which TiO 2 nanoparticles were evenly embedded on ultrathin Nb 2 O 5 nanosheets, were successfully synthesized for the first...

2019年11月13日 · High resolution transmission electron microscopy (HRTEM) images reveal the presence of lattice fringes, indicative of crystallinity, as well as the presence of defects...

Nb2O5 nanorods were fabricated by acetic acid solvothermal route combined with heat treatment of as-obtained one dimensional (1D) niobium oxide nanowires at 400°C for 1h.

2008年8月1日 · Nb 2 O 5 nanorods have been prepared using water/ethanol media. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–visible absorption and photoluminescence spectroscopy. The as-prepared Nb 2 O 5 nanorods appeared to be single pseudohexagonal (TT-Nb 2 O 5) phase.

2025年3月7日 · Abstract This work reports the synthesis of a mesoporous MoO3/Nb2O5 catalyst by a facile co-precipitation method for the liquid phase nitration of benzene to nitrobenzene, which is a vital industrial reaction. Pristine Nb2O5 and MoO3/Nb2O5 nanocatalysts were characterized using various techniques, including powder XRD, N2 adsorption-desorption, Raman, SEM/TEM, pyridine FT-IR, and XPS. The MoO3 ...
