2018年9月1日 · Electrochemical properties of Ti/SnO 2 anodes, such as oxygen evolution potential, current efficiency and service lifetime, have been enhanced significantly by Nb/Sb co-doping. Characterization of X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) indicated that Nb substituted Sn in SnO 2 lattice with the chemical state of Nb 5+.

2022年12月1日 · In this work, we fabricate Ti-doped NbFeSb alloys by levitation melting and spark plasma sintering (SPS) with different sintering temperature. Based on the optimized carrier concentration and the tremendously reduced κlat, TE properties of …

2018年9月1日 · 摘要 Nb/Sb 共掺杂显着提高了 Ti/SnO2 阳极的电化学性能，如析氧电位、电流效率和使用寿命。 X 射线衍射 (XRD) 和 X 射线光电子能谱 (XPS) 的表征表明，Nb 以 Nb5+ 的化学状态取代了 SnO2 晶格中的 Sn。

2022年1月25日 · Herein, we present electronic calculations using density functional theory (DFT) of non-stoichiometric Ti doped NbFeSb configuration, showing the effect of the anti-site Fe atoms on the electronic properties, and supporting them with experimental results of the prepared Nb 0.8 Ti 0.2 Fe 1+x Sb 1−x samples. The electronic structure of the non ...

2023年12月16日 · Ti/SnO 2 -Sb electrodes possess high catalytic activity and efficiently degrade nitrobenzene (NB); however, their low service life limits their wide application. In this study, we used one-step hydrothermal synthesis to successfully prepare Pt-Nd co-doped Ti/SnO 2 -Sb nanosphere electrodes.

The inherently low figure of merit (ZT) is the main impediment to the commercialization of half-Heusler thermoelectric materials in energy applications. Herein, we demonstrate the effectiveness of substituting Bi on the Sb site in the promising Nb0.8Ti0.2FeSb half-Heusler thermoelectric material to achieve m

2019年11月7日 · The effect of Nb content on microstructure, mechanical properties and superelasticity was studied in Ti-Nb alloys fabricated by powder metallurgy route using mechanical alloying and spark plasma sintering.

High-purity and relatively dense Ti1−xNbx (FeCoNi)Sb (x = 0, 0.01, 0.03, 0.05, 0.07 and 0.1) alloys were prepared via microwave synthesis combined with rapid hot-pressing sintering, and their thermoelectric properties are investigated in this work.

Results show that Ti/TiH x /Sb–SnO 2 not only possesses better stability but has higher oxygen evolution potential and lower electron transfer resistance compared with Ti/Sb–SnO 2. Essential characterizations were conducted including scanning electron microscopy, energy disperse spectroscopy, and X-ray diffraction.

2023年8月9日 · High-purity and relatively dense Ti 1-x Nb x (FeCoNi)Sb (x = 0, 0.01, 0.03, 0.05, 0.07 and 0.1) alloys were prepared via microwave synthesis combined with rapid hot-pressing sintering, and their thermoelectric properties are investigated in this work.
