Abstract

With its distinctive multiple electrochemical reaction, iron vanadate (FeV₃O₉.2.6H₂O) is considered as a promising electrode material for energy storage. However, it has a relatively low practical specific capacitance. Therefore, using the low temperature sol-gel synthesis process, transition metal doping was used to enhance the electrochemical performance of layered structured FeV₃O₉.2.6H₂O (FVO). According to this study, FVO doped with transition metals with larger interlayer spacing exhibited superior electrochemical performance than undoped FVO. The Mn-doped FVO electrode showed the highest specific capacitance and retention of 143 Fg^-1 and 87%, respectively, while the undoped FVO showed 78 Fg^-1 and 54%.

掺杂过渡金属的层状钒酸铁（FeV3-xMxO9.2.6H2O，M = Co、Mn、Ni 和 Zn），用于增强能量存储特性。

钒酸铁（FeV3O9.2.6H2O）具有独特的多重电化学反应，被认为是一种很有前途的储能电极材料。然而，它的实用比电容相对较低。因此，利用低温溶胶-凝胶合成工艺，过渡金属掺杂被用来提高层状结构 FeV3O9.2.6H2O (FVO) 的电化学性能。根据这项研究，掺杂了过渡金属且层间距较大的 FVO 比未掺杂的 FVO 表现出更优越的电化学性能。掺杂锰的 FVO 电极显示出最高的比电容和保持率，分别为 143 Fg-1 和 87%，而未掺杂的 FVO 则分别为 78 Fg-1 和 54%。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
