To determine the intensity of color for the complexes (Co(CN)6)3−, (Co(H2O)6)2+, and (Co(Cl)4)2−, we need to analyze the coordination geometry, the nature of the ligands, and their effects on the crystal field stabilization energy (CFSE). ...
The process can be proposed as follows15,30: Co(OH)2 + OH− ↔ CoOOH + H2O + e− (1) CoOOH + OH− ↔ CoO2 + H2O + e− (2) Ni(OH)2 + OH− ↔ NiOOH + H2O + e− (3) When increasing the scanning speed, an obvious phenomenon is that the position of anode...

The effects of various Co/Cu ratios on activity are also investigated, which can be easily adjusted by changing the mass of Co(NO3)2·6H2O and Cu(NO3)2·3H2O (Figure S21). Compared with other materials, the catalyst with the Co/Cu ratio of 5:1 had the best ORR and OER performances...

(CO + H2O → CO2 + H2)7and CO hydrogenation to methanol reaction (CO + 2H2 → CH3OH)8,9, are a representative example. This has inspired great efforts devoted to identifying the active sites of Cu–ZnO–Al2O3catalysts in both reactions. However, debates still ...
