Abstract:
Herein the role of a mononuclear cobalt(iii) complex, [CoIII(DPKOH)2]ClO4 (DPK = di(2-pyridyl)ketone), in the water electrooxidation process is investigated with scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction studies, NMR, chronoamperometry, cyclic voltammetry, extended X-ray absorption fine structure and X-ray absorption near edge structure determination. Our experiments show that, in comparison to the reported literature, other cobalt-containing structures on the surface of the FTO electrode could also be the true catalyst for water oxidation.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

States of Water
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
