β -Ni(OH) 2 and NiO nanostructured films were prepared on fluorine-doped tin oxide (FTO) glass substrates by using chemical bath deposition (CBD) at different concentrations of a complexing agent ( i.e. , NH 3 ). The as-deposited β -Ni(OH) 2 films exhibited various porous structures, such as nanoislands, nanoflakes, nanosheets and nanoplatelets, depending on the concentration of the complexing agent, and they could be converted to NiO films by using calcination. The β -Ni(OH) 2 and the NiO films were characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS). Importantly, the electrochemical activity of NiO nanoplatelet-films for the oxygen evolution reaction (OER) was also investigated as a function of the annealing temperature.

β-Ni(OH)2 和 NiO 纳米结构薄膜采用化学浴沉积法制备,用于放氧反应

通过在不同浓度的络合剂(即NH 3 )下使用化学浴沉积(CBD)在掺氟氧化锡(FTO)玻璃基板上制备β-Ni(OH) 2 和NiO纳米结构膜。沉积态的β-Ni(OH) 2 薄膜表现出各种多孔结构,如纳米岛、纳米薄片、纳米片和纳米片,取决于络合剂的浓度,它们可以通过煅烧转化为NiO薄膜。β-Ni(OH) 2 和NiO薄膜通过使用扫描电子显微镜(SEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)表征。重要的是,还研究了 NiO 纳米片膜对析氧反应 (OER) 的电化学活性与退火温度的关系。
