New discoveries in chemical research and development in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 108-32-7, Name is 4-Methyl-1,3-dioxolan-2-one, molecular formula is C4H6O3. In an article, author is Al-Zuraiji, Sahir M.,once mentioned of 108-32-7, Quality Control of 4-Methyl-1,3-dioxolan-2-one.
Herein, we compare the electrochemical and electrocatalytic properties of two selected, water-insoluble Fe(II) coordination complexes made with the non-symmetric, bidentate ligands, 2-(2′-pyridyl)benzimida zole (PBI) in [Fe(PBI)(3)](OTf)(2) (1, OTf- = trifluoromethyl sulfonate anion) and 2-(2′-pyridyl)benzoxazole (PBO) in [Fe(PBO)(2)(OTf)(2)] (2). Cyclic voltammetry in water/acetonitrile mixture indicates considerable activity for both compounds. However, only 1 acts as homogeneous catalyst. The complexes have been successfully immobilized on indium-tin-oxide (ITO) electrode surface. The hydrophobic ligands allowed for a simple dip-coating and drop-casting of 1 and 2 onto ITO. Both 1/ITO and 2/ITO showed increased activity in electrocatalytic O-2 evolution in borate buffer at pH 8.3. According to scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), moreover, re-dissolution tests, the Fe remains in complex with PBI during electrolysis in the drop-casted, nano-porous films of 1/ITO. In contrast, the PBO complex in 2/ITO undergoes a rapid in situ decomposition yielding a mineralized form that is responsible for catalysis. (C) 2019 The Author(s). Published by Elsevier Inc.
