Web8 de jan. de 2024 · In this work, γ-CoOOH was successfully synthesized from α-Co(OH)2, as a precursor, by electrochemical oxidation, without the use of any additives or high temperatures. The films were morphologically and structurally characterized using X-Ray Diffraction and Scanning Electronic Microscopy techniques. Cyclic voltammetry, … WebAbstract. We present an unusual, yet facile, strategy towards formation of physically mixed Ni–Fe(O x H y) oxygen evolution electrocatalysts.We use in situ X-ray absorption and UV-vis spectroscopy, and high-resolution imaging to demonstrate that physical contact between two inferior Ni(OH) 2 and Fe(OOH) catalysts self-assemble into atomically intermixed Ni–Fe …
