The paper proposes a new approach to Schiff-base ligand assisted sonochemical synthesis of iron vanadate. In this disquisition, we tried to comparing various factors and reaction condition on morphology, size and uniformity of as-obtained samples. Some parameters including Schiff-base capping agent (Bis(acetylacetone) ethylenediamine=Hacacen), electrolyte (NHF), solvent and reaction time were investigated to reach optimum condition. XRD, FT-IR, EDS, SEM and TEM were used in order to determine purity and structural morphology of as-synthesized products. Also, we explore the possibility of coupling vanadium pantaoxide into iron vanadate that improves optical properties and photocatalytic activity. With this in mind, FeVO/VO nanocomposite was prepared via in-situ ultrasound-assisted procedure by using NHF in one step. Influence of different parameters such as type of dye (Rhodamine B=Rh B, Phenol red=Ph R and Methyl violet=MV) and light source (Ultraviolet and visible) on photocatalytic ability of samples were studied.
本文提出了一种席夫碱配体辅助声化学合成钒酸铁的新方法。在本研究中，我们试图比较各种因素和反应条件对所得样品的形态、尺寸和均匀性的影响。研究了一些参数，包括席夫碱封端剂（双（乙酰丙酮）乙二胺 = Hacacen）、电解质（NHF）、溶剂和反应时间，以达到最佳条件。使用XRD、FT-IR、EDS、SEM和TEM来确定合成产物的纯度和结构形态。此外，我们探索了将五氧化二钒偶联到钒酸铁中的可能性，这改善了光学性能和光催化活性。考虑到这一点，通过一步使用NHF的原位超声辅助程序制备了FeVO/VO纳米复合材料。研究了不同参数，如染料类型（罗丹明B = Rh B、酚红 = Ph R和甲基紫 = MV）和光源（紫外线和可见光）对样品光催化能力的影响。
