Application

Molybdenum oxide nanoparticles have been studied in photocatalytic systems, as gas sensors for automobiles and as anodes in lithium ion batteries.
Precursor to LAMOX fast ion conductors and superconductors.
Used in the solid state synthesis of a remarkable ternary, reduced molybdenum oxide, Pr4Mo9O18, whose structure contains previously unknown Mo7, Mo13 and Mo19 clusters. The new cluster product is a small band gap semiconductor.
