      abstract     = {Industrially-applied mixed metal oxide catalysts often
                      possess an ensemble of structural components with
                      complementary functions. Characterisation of these
                      hierarchical systems is challenging, particularly moving
                      from binary to quaternary systems. Here a quaternary
                      Bi−Mo−Co−Fe oxide catalyst showing significantly
                      greater activity than binary Bi−Mo oxides for selective
                      propylene oxidation to acrolein was studied with chemical
                      imaging techniques from the microscale to nanoscale.
                      Conventional techniques like XRD and Raman spectroscopy
                      could only distinguish a small number of components.
                      Spatially-resolved characterisation provided a clearer
                      picture of metal oxide phase composition, starting from
                      elemental distribution by SEM-EDX and spatially-resolved
                      mapping of metal oxide components by 2D Raman spectroscopy.
                      This was extended to 3D using multiscale hard X-ray
                      tomography with fluorescence, phase, and diffraction
                      contrast. The identification and co-localisation of phases
                      in 2D and 3D can assist in rationalising catalytic
                      performance during propylene oxidation, based on studies of
                      model, binary, or ternary catalyst systems in literature.
                      This approach is generally applicable and attractive for
                      characterisation of complex mixed metal oxide systems.},
