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?
To date, the effect of oxidation state on activity remains controversial in whether higher or lower oxidation states benefit the enhancement of catalytic activity. Herein, we discover a volcanic relationship between oxidation state and hydrogen evolution reaction activity based on Os single-atom catalysts...

Electrocatalytic oxidation offers opportunities for sustainable environmental remediation, but it is often hampered by the slow mass transfer and short lives of electro-generated radicals. Here, we achieve a four times higher kinetic constant (18.9 min
However, traditional Ni/Al2O3 catalysts have difficulties, like deactivation due to coke deposition, requirement of reactivation under hydrogen flow as a result of strong oxidation tendency, hot-spot formation and additionally, sintering during oxidative steam reforming (OSR) reactions. In recent ...

The catalytic activity of metals supported on oxides depends on their charge and oxidation state. Yet, the determination of the degree of charge transfer at the interface remains elusive. Here, by combining density functional theory and first-principles molecular dynamics on Pt single atoms deposited...
Taking into account the oxide formation energies of well-optimized state-of-art Pt and Pd CO oxidation catalysts are − 133.9 and − 115.5 kJ/mol, respectively, the difference between the two studied systems can be explained by closer to the optimal value of Cu oxide formation (−...
