Here, we present a high-performance and durable heterostructure of NiMo/CoMoO 4 for the alkaline HER constructed via a two-pot in situ growth strategy on a nickel foam (NF). The density of active sites and the surface area of the hybrid catalyst augmented almost three-fold compared to those of pristine CoMoO 4.

β-CoMoO 4的透射电子显微镜 (TEM) 分析钼酸盐表示准球形颗粒，纳米尺寸范围为 10 至 60 nm。 紫外-可见光谱的分析使我们能够确认热致变色现象是由于 O 2- →Mo 6+电荷转移带向高能位移。

2017年1月20日 · The solid-state asymmetric CoMoO 4 @NiMoO 4 ·xH 2 O//Fe 2 O 3 supercapacitor device with a maximum voltage of 1.6 V shows high specific energy (41.8 Wh kg −1 at 700 W kg −1), power density ...

2022年8月10日 · In this work, we propose to prepare CoMoO 4 precursors by a simple hydrothermal method, and then fabricate N, S co-doped CoMoO 4 nanosheet arrays with atmosphere treatment strategy.

2022年11月1日 · Transmission electron microscopy (TEM) analysis of β-CoMoO 4 molybdate indicated quasi-spherical particles with nanometric sizes ranging from 10 to 60 nm. The analysis of the UV–Visible spectra allows us to affirm that the thermochromism phenomenon is due to the displacement of the O 2– →Mo 6+ charge transfer band towards high energies.

制备的样品通过 X 射线衍射 (XRD)、拉曼光谱、扫描电子显微镜 (SEM)、能量色散 X 射线光谱 (EDS)、透射电子显微镜 (TEM) 和 X 射线光电子能谱 (XPS) 进行表征）。

透射电子显微镜 （TEM） 图像验证了 Co3O4/CoMoO4 HNC 由 Co3O4/CoMoO4 异质结构组成。 X 射线光电子能谱 （XPS） 表征表明，与 CoMoO4 相比，Co3O4/CoMoO4 的 Mo 3d 峰位于较低的结合能下，表明 Co3O4 和 CoMoO4 之间存在电荷转移。
