Application

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.
Molybdenum oxide nanoparticles have been studied in photocatalytic systems, as gas sensors for automobiles and as anodes in lithium ion batteries.
