Fig. 1From: Multi-slice frozen phonon simulations of high-angle annular dark field scanning transmission electron microscopy images of the structurally and compositionally complex Mo–V–Nb–Te oxide catalystCation positions in the [001] projection of the MoVNbTe oxide M1 catalyst. Site colors correspond to crystallographically distinct cation sites. The black rectangle illustrates the size of the area simulated. The pentagonal (dark red), hexagonal (green) and heptagonal (light blue) rings of metal–oxygen octahedra are outlined above. Unit cell parameters [4]: Pba2 (no. 32); a = 2.1134(1) nm, b = 2.6647(1) nm, c = 0.40140(2) nmBack to article page
