2020年7月30日 · In this work, Co (OH) 2 hollow nanocubes derived CoS 2 @C composite was successfully synthesized through the carbon coating and sulfidation processes. The three-dimensional hollow architecture can not only effectively restrict the volume expansion, but also shorten the ion/electron transport pathway and provide more active sites for reaction.

Herein, we report the simple one-step hydrothermal synthesis of cobalt sulfide nanoflakes decorated with reduced graphene oxide (CoS/rGO) nanocomposites as an effective electrode material for...

2022年3月1日 · Herein, a rationally designed oxide/sulfide heterostructures, which named as CoO/CoS 2, are successfully realized. Benefited from the electrons interaction between multiple components at the heterojunction interface and the defect structure, the CoO/CoS 2 displays highly effective bifunctional catalytic performance and robust durability.

2021年9月1日 · Thereby, coupling of GDY with CoS 2 nanowire material could supply more active sites of carbon atoms in the acetylene bonds and the unsaturated sulfur in CoS 2 for improving the intrinsic catalytic performance of catalytic hydrogen composite material, which may because of the strong electronic interactions between GDY and CoS 2 confirmed by ...

Zhao Wang et al. developed a self-standing CoS 2-CNFs electrode with CoS 2 nanoparticles and reported that CoS 2 -CNFs exhibited excellent performance with a high specific capacitance of 488...

As shown in Figure 3 a, the XPS spectrum of CoS x before the OER measurement clearly shows the peaks at binding energies of 163, 227, 532, and 798 eV, which belong to the signals of S 2p, S 2s,...

XPS 光谱解读. O1s 谱图的解读较复杂。 除金属氧化物外，许多化合物和氧化物的 O1s 结合能对应的范围非常窄。 O1s 峰一般较宽，有多个重叠峰。 例如，因存在水和/或有机化合物污染而导致与 SiO 2 峰干扰严重。 有机化合物污染还导致难以区分 O1s 区域的碳酸盐类 ...

To investigate the electronic structure of the deposited composition, X-ray photoelectron spectroscopy (XPS) measure- ments were utilized. The complete survey spectrum of the electrochemically...

在本文中，我们对C（1s）和O（1s）核心能级与X射线光发射XPS中测量的BE的理论结合能BE的符号和误差幅度进行了研究。实验。特别是，我们解释了由于CO（1π）和CO（2π）水平几乎简并引起的相关效应，Hartree-Fock C（1s）BE的错误符号出乎意料，它比实验要大。
