The activity of molybdenum and molybdenum oxide model catalysts for olefin metathesis

XPS studies on the Mo oxide-based coatings electrodeposited from highly saturated acetate bath

“…It was found that the catalytic activity decreases in the following sequence: MoO 2 > MoO 3 > Mo [19]. Such findings provide motivation for the development of a simple electrodeposition procedure for preparation of more active metallic molybdenum films that would be combined with its oxides in a synergetic manner to yield a surface which is more active than each of the components separately.…”

Nonclassical Crystallization and Size Control of Ultra-Small MoO2Nanoparticles in Water

“…Nevertheless, abrupt capacity fading occurs after 10 cycles. MoO 2 and Mo obtained after discharge are indeed well known for their catalytic properties, which are exacerbated for nanoparticles . The active material can then catalyze electrolyte degradation of the electrolyte as already observed during the CoO conversion reaction .…”

“…MoO 2 and Mo obtained after discharge are indeed well known for their catalytic properties, which are exacerbated for nanoparticles. [2][3][4][5][6][7][8][9][10][11][12][13] The active material can then catalyze electrolyte degradation of the electrolyte as already observed during the CoO conversion reaction. [ 42 ] Moreover, these small nanoparticles are more soluble into the electrolyte as demonstrated by the blue color of the electrolyte at the end of cycling, characteristic of Mo(VI)/Mo(V) mixtures.…”

“…Molybdenum oxides attract great interest from a broad range of scientifi c communities, especially dealing with catalysis and energy storage. MoO 3 is for instance considered for the design of supercapacitors, [ 1 ] while MoO 2 is intensively scrutinized as a catalyst, [2][3][4][5][6][7][8][9][10][11][12][13] Li-ion battery anode material, [14][15][16][17][18][19][20][21][22][23][24][25][26] for its pseudocapacitive [ 17 ] and electronic [ 27 ] behaviors. www.particle-journal.com www.MaterialsViews.com…”

Evaluation of two processing routes for the synthesis of molybdenum oxide with cobalt addition

“…Metal oxides over support materials are, therefore, used as catalysts in a large variety of commercial processes that involve the conversion of hydrocarbons, such as hydrotreatment reactions [5]. Among metal oxides, molybdenum oxide, particularly, presents a set of properties which, in addition to its multiple oxidation states, may be interesting in electrochemical storage [6], heterogeneous catalysis [7], and photocatalysis [8]. Recently, much attention has been paid to the preparation and performance of mixed metal oxide catalysts, as the addition of a second metal to the oxide structure could change electronic and structural characteristics of the material, leading to superior final behavior in those areas.…”
