Crystal Structure of a Metastable Form of Indium Orthovanadate, InVO4-I

Influence of point defects on the performance of InVO₄ photoanodes

“…11 In order to be a useful photoanode material, InVO 4 should be photochemically stable in aqueous solutions. The stability of InVO 4 films deposited on quartz has been investigated for aqueous solutions with pH values between 1 and 14.…”

Synthesis and properties of Fe0.83V1.17O4

“…Phase X crystallizes in the monoclinic system and its endcentered (C) unit cell parameters are given in Table 4. The literature scan has shown that angular positions of diffraction reflection, their relative intensities and unit cell parameter of phase X are similar to these ones of Fe 1-x Cr x VO 4 solid solution phase, CrVO 4 -I and InVO 4 -I, which are isostructural with a-MnMoO 4 [13][14][15][16]. It permits advancing suggestion, that phase X belongs to a group of orthovanadates, MVO 4 , isostructural with a-MnMoO 4 .…”

“…Thus, the structure of the Fe 1-x Cr x VO 4 phase differs essentially from the stable at ambient conditions structures of triclinic FeVO 4 -I and orthorhombic CrVO 4 -III. On the other hand, soft chemistry synthesis methods lead to formation of CrVO 4 -I and InVO 4 -I isostructural with a-MnMoO 4 [15,16].…”

Influence of point defects on the performance of InVO 4 photoanodes

“…Its main features are the high stability over a wide pH range (3)(4)(5)(6)(7)(8)(9)(10)(11), and the previously reported flatband potential of -0.04 V vs. RHE that enables hydrogen evolution. 10 The presence of deep donor states in the material leads to visible light absorption at photon energies >2.5 eV.…”
