Crystallography studies of as-prepared CoxMg1−xO.
a, A XRD pattern of the CoxMg1−xO solid solution. b, A TEM image of a representative cube particle of the CoxMg1−xO solid solution with a close up of the particle as an inset showing clearly lattice fringes of the structure. c, An EDX spectrum of the materials measured on a similar particle to that shown in b. The region of interest (inset) indicates the presence of Co in the materials. The spurious Cu signals originate from the TEM grid.
