图4. 非原位XPS和TEM分析。(Bi-Sb)₂S₃@N-C 阳极表现出卓越的长循环稳定性，这得益于双金属的协同效应和先进的中空纳米结构。通过原位 TEM 技术（图5），揭示了 N-C 层在缓和钾化过程中的体积膨胀和防止结构坍塌方面的积极作用。完全去钾后，观察到纳米立方体略微膨胀，这可归因于不完全放电过程和 SEI...
其中最佳复合样品BB-BS60对NOx的去除率是BB的1.5倍,但NO2−/NO3−生成选择性能从BB的从60%提升到BB-BS60的90%,这也说明NO2的形成被显著抑制。其中NO2−/NO3−的生成可以通过FT-IR光谱和XPS分析证实。本文系统地讨论了光催化性能和NO2−/NO3−生成选择性的变化,主要归因于体系通过Z-scheme的n-p异...

C3N4/Bi3TaO7表面复合光催化剂。水热法制备的Bi3TaO7颗粒的粒径为20?40nm,这种纳米尺寸的Bi3TaO7与三聚氰胺煅烧的过程中,Bi3TaO7能够很好的复合到生成的片状g?C3N4表面,而且在g?C3N4和Bi3TaO7界面上形成化学作用连接,有效的增强g?C3N4/Bi3TaO7表面复合光催化剂光催化性能,也提高了复合光催化剂的稳定性。
(FTIR), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) techniques. From the thorough investigation, it is revealed that the CY molecules reached adsorption–desorption equilibrium onto the surface of the catalyst within 30 min following second-order kinetics. Herein, the ...
According to energy-dispersive X-ray(EDX) and X-ray photoelectron spectroscopy (XPS) analyses of the wornpathway, the generated tribo-film comprised metal oxides, Bi 2 O 3 , SeO 2 , WO 3 , and tungsten nitride,which synergetically improved the lubricity. The wear scar surfaceanalysis by ...
Finally, this research analyses the themoeleletric performance, crystal structure and composition by XRD, XPS, Hall effect and the Seebeck effect. This research discovers that the P-type Bi0.5Sb1.5Te3 thermoelectric thin films show the best thermoelectric properties at room temperature with 18 ...
