Selective oxidation of toluene over layered structures of Bi2MoO6 and La2MoO6

Oxygen‐Deficient R2MoO6–δ (R = Tb, Dy, Y, Ho, Er, Tm, Yb) with Fluorite Structure as Potential Anodes in Solid Oxide Fuel Cells

“…[1] Among them, the family of R 2 MoO 6 molybdates (R = rare earths or Bi) displays appealing catalytic properties in the oxidation of hydrocarbons. For instance, Bi 2 MoO 6 is an extensively used catalytic component for selective olefin oxidation; [2] La 2 MoO 6 and Pr 2 MoO 6 [3][4][5] have also been described as catalysts in the selective oxidation of toluene and isobutene, respectively. Moreover, a related compound, La 2 Mo 2 O 9 , was reported to be a fast oxide-ion conductor with an ionic conductivity of 6 ϫ 10 -2 Scm -1 at 800°C, comparable with other widely used solid oxide fuel cell electrolytes.…”

Novel Nd2WO6-type Sm2−xAxM1−yByO6−δ (A=Ca, Sr; M=Mo, W; B=Ce, Ni) mixed conductors

“…These compounds exhibited about three orders of magnitude higher total conductivity in wet H 2 compared to that in air at low temperatures due to the reduction of Mo VI and Ce IV . In our incessant efforts in searching new anode materials, we have encountered a new family of fluorite-related structure materials with chemical composition of Sm 2 MoO 5 (SMO) and Sm 2 WO 6−ı (SWO) and the former compound can be prepared from the Nd 2 WO 6 -related structure Sm 2 MoO 6 [17][18][19][20][21][22][23][24][25][26][27][28][29][30] by topochemical reduction in H 2 [18].

Structure refinement and superspace description of the system Bi2(n + 2)Mo n O6(n + 1) (n = 3, 4, 5 and 6)

“…Due to the functional properties of some compounds obtained within the Bi 2 O 3 -MoO 3 system, mainly catalysts (Galvan et al, 1993;Agarwal et al, 1994) and good ionic conductors (Vannier et al, 2000;Galy et al, 2006;Holmes et al, 2008), this binary system has been extensively studied. Within this context, four new compounds, Bi 10 Mo 3 O 24 , Bi 6 Mo 2 O 15 , Bi 14 Mo 5 O 36 and Bi 8 Mo 3 O 21 , have been found in the mBi 2 O 3 -MoO 3 system, corresponding to m = 1.666, 1.500, 1.400 and 1.333 (Vila et al, 2004(Vila et al, , 2005(Vila et al, , 2007.…”
