Room-temperature co-precipitation synthesis of (Ca,Sr,Ba)WO4 solid solutions: Structural refinement, morphology and band gap tuning

Development of Z-scheme bimetallic tungstate-supported nitrogen deficient g-C3N4heterojunction for the treatment of refractory pharmaceutical pollutants

“…The detected band at 525–518 cm −1 was caused by the asymmetric stretching of O–W–O–W–O distorted octahedral [WO 6 ]–[WO 6 ] in the nanocomposites. 33 The Ni–O, Co–O and Zn–O bond vibrations were the cause of the active mode at 418–438 cm −1 . Consequently, the FTIR data confirm the effective incorporation of NCW and CZW nanoparticles into ND-GCN nanosheets.…”

Adhesion, stability, structural and electronic properties of perovskite/BaWO4 heterostructures: first-principles and experimental characterizations

“…Barium tungstate (BaWO 4 ) with a scheelite structure is known for its high ionic/electronic conductivity and high thermal/chemical stability, and has potential applications in catalysis. [23][24][25][26] Recently, the heterostructural growth of CsPbBr 3 and MAPbBr 3 NCs on a BaWO 4 crystal was successfully demonstrated based on lattice matching. 27,28 Compared to the pure perovskite, the perovskite/BaWO 4 heterostructures exhibited enhanced luminescence intensity and sustained stability against UV-light radiation, heat, and diverse solvents.…”

A Chemical-Pressure-Induced Phase Transition Controlled by Lone Electron Pair Activity

“…Solid solutions of semiconductors are pertinent examples to illustrate how the interactions associated with the doping process mimic the effect of thermodynamic variables (pressure and temperature) and also modulate the properties of advanced materials with extended functionalities (see for example refs , ). Among these solid solutions, the ternary metal tungstate- and molybdate-based compounds form an important class of multifunctional materials with a combination of covalent, ionic, and metallic bonding that has been widely studied due to their fundamental and industrial interest. − In spite of being in the next period, tungsten shows a similar atomic radius as molybdenum due to the well-known lanthanide contraction. This good size matching guarantees the alloying of the two semiconductors in a wide composition range and avoids the phase separation that otherwise would occur originated by large lattice-mismatching strains.…”
