In situ laser Raman studies of the mechanism of ethanol oxidation over supported molybdenum oxide
"Ethanol oxidation over supported molybdenum oxide was studied by in situ laser Raman spectroscopy, deuterium isotopic substitution, together with steady-state and transient reactivity and kinetic measurements. The combination of techniques allows a complete description of the mechanism of ethanol …

The influence of molybdenum and vanadium on the activity and selectivity of a cobalt Fischer-Tropsch catalyst
… literature on CO hydrogenation indicates that molybdenum oxide and vanadium oxide used as a promoter may be beneficial for the activity and selectivity of a cobalt based catalyst. To eliminate the structural influence on the selectivity by using commercial MoO3 and V2O5 supports, and alumina …

Mesoporous Carbon/Silica Encapsulated Molybdenum and Ruthenium Nanocatalysts For Green Chemistry Applications
… for green chemistry applications. In this work, molybdenum oxide and ruthenium nanoparticles were selected as model metal oxide and metal compounds to be encapsulated within mesoporous carbon and silica supports. The resulted nanocatalysts (e.g., Mo@C, H4SiMo12O40@mSiO2, Mo/mSiO2, and Ru@mSiO2) …

Promotion of Heterogeneous Acid and Base Catalysts for Biomass Upgrading
… leveraged the acid-base pairs on alkaline earth oxides to generate novel monomers for chemically recyclable plastics. First, we show how applied electrochemical potentials can be used to enhance Brønsted acid-catalyzed dehydration reactions over a molybdenum oxide film on an yttria-stabilized …

Low-dimensional purple and blue bronzes: Crystal growth, characterization and optical properties
The molybdenum oxide bronzes are a family of charge-density-wave (CDW) conductors with distinctive properties originating from their low-dimensional crystal structure and associated Fermi surface instabilities. Single crystals of potassium blue and purple bronzes and sodium purple bronze have been …
