Atomic layer deposition of MoO3 on mesoporous γ-Al2O3 prepared by sol–gel method as efficient catalyst for oxidative desulfurization of refractory dibenzothiophene compound

Superior stability and activity of a PbMoO4/BiOBr nanocomposite for enhanced catalytic oxidative desulfurization of actual fuel

“…Additionally, the peak at 990 cm À1 corresponds to the asymmetric stretching modes of MoQO. 32 The peak at 1102 cm À1 was assigned to the asymmetric stretching vibration of Pb-O. 33 The strong peak at 840-740 cm À1 is the characteristic absorption peak of Mo-O and Pb-O.…”

Facile synthesis of ZnMoO4/AlPO4-5 nanorod composites as visible-light-driven photocatalysts and high-performance energy storage materials

“…9 Thus, molybdenum oxides are very close to existing as MoO 3 phase in agreement with the XRD results. 33 The XPS results conrm that in the ZnMoO 4 nanocrystals obtained; there are valence states of +2, À6, and À2, respectively. It was noticed that by increasing Mo : Zn molar ratio while maintaining the Mo content constant, the XPS peak intensity decreased by increasing the Mo content concentration up to Zn : M (6)/AlPO 4 -5 catalysts.…”

Synthesis of highly-uniform titania overcoats on a mesoporous alumina catalyst support by atomic layer deposition and their application in hydroprocessing

“…20 Furthermore, MoO 3 active phase growth on mesoporous alumina by ALD and its application in oxidative desulphurization has been reported. 21 ALD synthesis was anticipated to lead to a homogeneously distributed Ti layer, fully covering the accessible surface of the support. Moreover, contrary to conventional used synthesis methods it provides the possibility to avoid the use of solvents, thus drastically minimizing the generation of synthesis process-related waste.…”
