(American Chemical Society, 2019-01)
The geometric, electronic, and magnetic properties of Mo m Co n (3 ≤ m + n ≤ 8) and Mo x W y Ni z (3 ≤ x + y + z ≤ 8) clusters, as models for the hydrodesulfurization process, are investigated from a computational point ...
Structural and compositional effect of heteropolyoxoanions [NiMo6-x WxO24H6]4- on the catalytic activity of clean selective oxidation of diphenylsulfide
(Bentham Science Publishers, 2014-02)
Diphenyilsulfide oxidation by H2O2 as oxidant was studied through the structural effect of the isomorphous W-Mo systems, Anderson type, with [Ni(II)Mo(VI)6-xW(VI)xO24H6]4- composition. These phases were proved as alternative ...
