2022年1月1日 · The partial densities of states (pDOS) for Co 3 O 4 (Fig. S1) shows that the valence band maximum (VBM) and conduction band minimum (CBM) are mainly dominated by Co 3d and O 2p orbits, indicating that transition metal d orbits play a …

2018年7月27日 · Benefiting from the unique honeycomb composite structure composed of monodisperse Co 9 S 8 nanoparticles in situ embedded within the three-dimensional interconnected network carbon matrix with...

2023年6月1日 · We report the formation of flower-like Co9S8/MoS2/C composites by a simultaneous vulcanization-carbonization process using MoCl5 as the Mo source and a 2-methylimidazole cobalt salt as the Co and C precursor at different temperatures (600, 700 and 800 ℃) in sublimed sulfur.

2024年1月24日 · An inverse-opal-structured cobalt sulfide@nitrogen-doped-carbon (Co9S8@NC) is developed as a catalytic host of the iodine electrode, specifically targeting improved reaction kinetics for the two-elec...

2025年2月1日 · In this research, a three-phase transition metal sulfide nanoflower (Co 9 S 8 /Co 1-x S/WS 2) was designed and used as a bifunctional oxygen electrocatalyst. The structure of transition metal sulfides was optimized by modulating the sulfidation temperature, which enhanced the electrocatalytic performance of the catalysts for oxygen.

The metallic Ni2P@Co9S8 heterostructure is a highly efficient and stable bifunctional catalyst for overall water splitting. The electron transfer from Co─Co bonds of Co9S8 to active Ni sites of Ni2P ...

2022年10月21日 · The d-band partial density of states (PDOS) of Co atoms in CoO 2 /Fe-Co 9 S 8 and the p-band PDOS of O atoms were analyzed to predict the adsorption intensity of oxygen intermediate species in the OER process (Figure 4a).

Figures 8 and 9 show the projected density of states (pDOS) of surface cobalt and sulfur atoms in the stoichiometric slabs, together with the crystal orbital overlap population (COOP) analysis.

本工作利用水热法成功构建具有优异电化学活性的Co9S8@Fe3O4异质结构催化剂。研究结果表明，得益于Fe3O4发挥的“栅栏”作用，在OER过程中Co9S8组分经历了Co9S8→CoOx→CoOOH的重构过程，但是整个催化剂三维形貌结构并未发生坍塌。

2016年9月9日 · Here we report Co 9 S 8 nanoparticles grown in situ on nitrogen- and sulfur-doped porous carbon (Co 9 S 8 /NSPC) as a bifunctional catalyst for OER and ORR using poly (2-aminothiazole) as a...
