“…Up to now, only a few preparation of Mn(VO3)2 have been reported. For example, Mn(VO3)2•yH2O compounds were synthesized with a precipitation method [13][14] or refluxing route with the mixture of V2O5 with Mn(CH3COO)2 in water medium [15]. The powder form of Mn(VO3)2 can also be reached via route-rheological phase reaction method or polymer gellation method [16][17].…”

Adopting MnSO4•H2O and K6V10O28•9H2O as the manganese and vanadium source, respectively, the Mn(VO3)2 product was obtained by the facile one-step hydrothermal method under different pH conditions without adding any additives. The effects of pH on microstructure and photoactivity were investigated. The photocatalytic results demonstrate that Mn(VO3)2 prepared at pH = 5.0 showed optimal photoactivity in the photodegradation of RhB under UV light irradiation，and 95% of RhB was degraded by irradiation within 80 minutes, offering a new insight with the functional materials in the application of the photochemistry field.

“…The most studied compounds in this respect are Ni 3 [7][8][9][10][11] and a mixed-ion vanadate LiNiVO 4 [12][13][14][15][16]. In fact, the simplest nickel vanadate Ni(VO 3 ) 2 itself does not suit in such applications; however, synthesis of Ni(VO 3 ) 2 doped by lithium ions represents a viable option for the development of a different class of lithium-ion batteries [17,18]. Therefore, the research on innovative methods for the synthesis of nickel vanadates including Ni(VO 3 ) 2 capable of accommodating lithium ions is ongoing.…”

Trapping ionic dimers of dinuclear peroxido mandelato complexes of vanadium(V) into cavities constructed from Δ- and Λ-[Ni(phenanthroline)3]2+ cations: a precursor to Ni(VO3)2

A nickel-vanadium metal-organic hybrid compound [Ni(phen) 3 ] 2 [(V 2 O 2 (O 2) 2 ((S)-mand) 2)][(V 2 O 2 (O 2) 2 ((R)-mand) 2)]•18H 2 O (phen = 1,10-phenanthroline, mand 2− = mandelato(2−) ligand, C 6 H 5-CO-COO 2−) (1) was prepared and characterized by spectral methods, X-ray structure analysis and simultaneous DTA and TG measurements. The crystal structure of 1 contains both Δ and Λ enantiomers of the [Ni(phen) 3 ] 2+ cations that construct sandwich layers along the crystallographic axis c, in between which sit the vanadium(V) complex anions. These are present as ionic dimers in the form of a robust {[(V 2 O 2 (O 2) 2 ((S)-mand) 2)][(V 2 O 2 (O 2) 2 ((R)-mand) 2)]} 4− species. The two individual anions are coupled by a pair of weak, yet significant attractions between two vanadium atoms and two peroxido ligands of the adjacent anion at V-O distances 2.660 Å. The 51 V NMR spectrum of the compound in DMSO solution revealed a complicated course of decomposition reactions of the anion, which led to formation of the [(V 2 O 4 (S,R-mand) 2 ] 2− anion as a single product. The metal-organic hybrid compound 1 is converted by thermal decomposition into a potential anode material for lithium-ion batteries Ni(VO 3) 2 .

Manganese vanadate microtubes have been synthesized by a facile polyvinyl pyrrolidone-assisted hydrothermal route. X-ray diffraction pattern confirms that the microtubes are composed of monoclinic MnV2O6, tetragonal V2O5 and orthorhombic MnO2 phases. The outer diameter and inner diameter of the microtubes are about 300 nm-3 µm and 200 nm-1 µm, respectively. The tube wall thickness of the microtubes is about 50 nm-1 µm. The possible formation process of the manganese vanadate microtubes has been proposed as a polyvinyl pyrrolidone-assisted growth mechanism
