SEM和TEM结果显示了双金属硒化物异质结构在还原氧化石墨烯(rGO)表面的成功构建和均匀生长,且表现出分层片状结构,同时在靠近Cu2Se的区域生成有大面积的1T相MoSe2,Raman和XPS光谱结果(图3)同样证实了1T相MoSe2的生成,同时显示出了由Cu+...
In situ Raman observation of the phase transformation process from 1T’-MoS2 to 2H-MoS2 under laser irradiation About this article Cite this article Yu, Y., Nam, GH., He, Q.et al.High phase-purity 1T′-MoS2- and 1T′-MoSe2-layered crystals.Nature Chem10, 638–643 (2018). https://...
Several MoSe2samples with different phase structure were prepared by a NaBH4-assisted hydrothermal method. The XRD patterns and Raman spectra were conducted to determine the phase structures and compositions. In the XRD patterns (Fig. 1a), all the MoSe2exhibited the similar diffraction peaks correspo...
Raman spectroscopySelenium sourceIn this report MoSe2 nanosheets were fabricated using new precursors of MoCls and Na2SeO3 and a very simple chemical procedure without using inert atmosphere and complex methods for preparing Se ion source. The structural properties of fabricated nanosheets were examined ...
利用图2中所显示的简单水热和退火过程,制备出了具有双异质结构的G-Cu2Se@MoSe2复合材料,SEM和TEM结果显示了双金属硒化物异质结构在还原氧化石墨烯(rGO)表面的成功构建和均匀生长,且表现出分层片状结构,同时在靠近Cu2Se的区域生成有大面...
Electrodeposited Mo films on graphite and nanowires in AAO were thermally selenized.Effect of temperature and selenization duration were studied.2H MoSe2and 1T/2H MoSe2were successfully obtained by two-step synthesis method.The materials were characterized by FE-SEM, EDS, XRD, XPS and Raman ...
