2017年3月1日 · In situ X-ray diffraction analysis reveals the reaction mechanism of NiSe 2 /rGO. The influence of cut-off voltage on electrochemical performance is investigated. NiSe 2/rGO hybrid exhibits excellent cycling stability for sodium ion batteries.

2025年1月1日 · In this work, pristine nickel diselenide (NiSe 2) and Co induced nickel diselenide (NiCoSe 2) nanoparticles (NPs) were prepared through a facile hydrothermal method. The prepared NPs were examined using the XRD, FT-IR, SEM/EDX, TEM/SAED, XPS, VSM and cyclic voltammetry (CV) analysis.

2021年12月15日 · The XRD pattern (Fig. S6a) indicates that the NiSe2 /CoSe 2 is composed of both the NiSe 2 and the CoSe 2, illustrating the successful construction of this desired heterojunction.

Download scientific diagram | XRD patterns of NiSe 2 /RGO NPs and NiSe 2 NPs samples (a). The standard diffraction patterns for NiSe 2 (JCPDS no. 41-1495) appear below the pattern.

2025年3月1日 · The crystalline structure, morphology and chemical compositions of the produced diselenide particles were thoroughly characterized by confirmed by XRD, FT-IR, HRSEM, and XPS studies and their performance toward magnetic electrochemical were tested.

Here, we elaborately design the free-standing NiSe2@NiO heterostructure on conductive carbon cloth as oxygen electrode for Li-O2 batteries.

2020年2月21日 · Powder X-ray diffraction (XRD) was used to investigate the phase purity and crystallinity of prepared samples (Cu Kα = 0.15418 nm). X-ray photoelectron spectroscopy (XPS) was employed to examine the surface chemical states.

Tetrahedral NiS2/NiSe2 heterocages with rich‐phase boundaries are synthesized through a simultaneous sulfuration/selenylation process using Ni‐based acetate hydroxide prisms as precursor.

为了进一步探究电池的可逆转换能力以及副产物情况进行了一系列表征测试，如XRD、EIS、DEMS和XPS等测试，结果表明NiS2/NiSe2同源异质笼催化下的锂-氧气电池的放电产物主要为Li2-xO2，且副产物的形成受到有效抑制。

该观点文章分析了异质结构和自旋态之间的关系，NiS2/NiSe2异质结构可促进3d轨道的自旋分裂，推动Ni3+从低自旋转变为高自旋，从而产生额外的未成对电子。
