To determine the oxidation state of nickel (Ni) in the complex (Ni(CO)4), we can follow these steps: 1. Identify the overall charge of the complex: The complex (Ni(CO)4) is neutral, meaning its overall charge is 0. 2. Determine the contribution of the ligands: In this complex,...
Enter just an element symbol to show the common and uncommon oxidation states of the element. 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 你可以用小括号()或括号[ ]。 What is an oxidation state? The oxidation state or oxidation number ...

The accessible reduction events observed for (RN3)NiCl2 suggest that for these complexes the NiI oxidation state is accessible via one-electron reduction with a chemical reductant and thus it can be exploited in reactivity and mechanistic studies. When compared to (dtbbpy)NiCl2, the (RN3)NiC...

(−0.53 V) versus NHE. Electrons are photoexcited from the VBM to the CBM of LaNi-Phen/COF-5, which enables the reduction of adsorbed CO2molecules to CO. Besides, for the oxidation half-reaction, the photoexcited holes in the VB of LaNi-Phen/COF-5 are consumed by the electrons ...
首先,4K下CO2随机分布在CuO表面的-Cu-O-链间,随着进一步升温,Ni2团簇水平吸附表面迁移的CO2并进一步活化CO2,CO2其中一个O原子与Ni2团簇中的Nic原子化学成键,而C原子与基底Cu原子结合,当进一步升温后,CO2分解形成CO和O物种。 图2 CO2在Ni2团簇上的吸附、活化和解离过...
It has been reported that compared to metal nanoparticles, supported metal clusters (SMCs) in high oxidation states have less adsorbing strength to CO, allowing a higher CO selectivity in CO2 hydrogenation22,26. However, the stability of SMCs is usually negatively correlated with their surface ...
