Single-crystalline nanoporous Nb2O5 nanotubes were fabricated by a two-step solution route, the growth of uniform single-crystalline Nb2O5 nanorods and the following ion-assisted selective...

This procedure contained two steps: the hydrogenation of 5-hydroxymethylfurfural (HMF) to 1-hydroxy-2,5-hexanedione (HHD) in water on Pd/Nb2O5 catalysts... [...] Mn3O4 coated Ru nanoparticles...

2017年3月15日 · This work has revealed Nb2O5 nanoparticles as a new semiconductor surface-enhanced Raman scattering substrate that is able to replace noble metals and shows great potentials applied in the fields...

The XRD result confirms the presence of Nb2O5 with low crystallinity for both precursor samples. The SEM images show differences between the material morphologies but with the same aggregation...

你好，我的数据就是XRD数据呢，可以用JADE打开，我也是找不到呢，奇怪！ 附件中是对应的TXT格式的. 不知道你是不是采用sol-gel制备的?你确定知识产物而不是原料? 这个应该是确定 …

2019年4月29日 · X-ray diffraction (XRD) and Raman spectroscopy confirmed the tetragonal phase of NbO2 and orthorhombic phase of Nb2O5 for similar deposition temperatures. Scanning electron microscopy (SEM) observations indicate that NbO2 has a unique nanoslice structure while Nb2O5 has a flake-like structure.

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.

2018年12月1日 · XRD patterns of the synthesized Nb 2 O 5 samples: (a) TT-Nb 2 O 5-500, (b) TT-Nb 2 O 5-600, and (c) T-Nb 2 O 5-700. The morphology and structure of all prepared Nb 2 O 5 samples were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).

2022年7月1日 · Unprecedent crystal evaluation of the TT-Nb 2 O 5 employing powder XRD. TT-Nb 2 O 5 presents disordered pseudohexagonal subcell domains. The TT-Nb 2 O 5 shows an orthorhombic superlattice structure. The TT-Nb 2 O 5 presents a tunnel-like structure along the b-axis with 4 Å diameter.

2006年2月1日 · In the present work, we examined the crystallographic characteristics and electrochemical charge–discharge behaviors of phases formed by heat-treating niobium hydroxide at different temperatures in the range .
