The present work highlights the suitability of polyaniline-coated niobium pentoxide (PANI-Nb2O5) nanocomposites as promising EMI shielding material with anticorrosion behavior.

2017年7月1日 · The structural changes are in agreement with FTIR spectra, where TeO 4 units are partially converted into TeO 3+1 and TeO 3 units with the variation of B 2 O 3 and Nb 2 O 5 in the glass system. As Δ g || /Δ g ⊥ decreases, there is an improvement in octahedral symmetry at the vanadium ion site and the degree of distortion dependent on the ...

The 1%Fe-Nb2O5 sample showed the best photocatalytic discoloration result, achieving 100% discoloration of RhB within 60 minutes. The increase in ion concentration leads to a decrease in ...

2024年11月1日 · Optical constants of Nb2O5 films determined in unprecedented spectral range. Optical characterization using multi-instrument and multi-sample method. Physically consistent universal dispersion model employed.

结果表明，含氧缺陷的Nb2O5纳米片的CH4生成速率为19.14 μmol g-1 h-1，电子选择性高达94.1%。 这一调控提高了CH4生成的选择性，为有效地调整CO2光还原过程中的产物选择性提供了新的见解。 背景介绍. 如今，化石燃料的过度消耗导致大量二氧化碳（CO2）的释放，造成了全球变暖、酸雨、海平面上升等全球气候变化。 尽管有这些缺点，CO2仍然是在许多化学工业中应用的C1原料。 由于太阳能这一可再生能源，光催化CO2还原被认为是将CO2转化为增值化学品或 …

2021年3月1日 · The results are in accordance with the FTIR spectrum of Figure 1SI, where is it seen bands in regions of 610 cm −1 and 880 cm −1 characteristics of Nb-O and Nb-O-Nb stretching (Graça et al., 2013, Jin et al., 2014, Music et al., 2004).

This article reports the characterization of mesoporous Nb2O5 synthesized by the sol-gel method for application in photocatalysis. The emerging contaminant methylviologen was employed for ...

2017年3月15日 · In this work, a semiconductor based on Nb 2 O 5 is reported as a new candidate for highly sensitive surface-enhanced Raman scattering detection of dye molecules. The largest enhancement factor...

2022年9月26日 · FTIR measurements reflected that relative fraction of BO4 (P4) decreases while relative fraction of BO3 (P3) increases by Nb2O5 doping. Such a result confirmed that the Nb ions cause a variation in borate structural coordination and partially back conversion from [BO4] to [BO3] units in the glass network.
