The temperature-dependent behavior of the low-and intermediate-temperature phases of -Bi 2 MoO 6 were investigated. As revealed by high-resolution neutron and synchrotron powder di4raction as well as electron di4raction, the low-temperature Aurivillius phase shows a previously undetected incommensur

We report a detailed in situ study of the preparation of the -phase Bi 2 MoO 6 catalyst from a gel. In particular, the local coordination around molybdenum remained tetrahedral, although the poorly crystalline bismuth molybdate phase started to appear below 4003C; above this temperature there was a
