“…Interestingly, the original nanosheet samples Ni(OH)(2)-200 and NiO-300 still maintained their morphology and structure although they all went through an activity test at 500 °C in a 1.0% CH(4) atmosphere, which proves that the calcination of nanosheets in a CH(4) atmosphere tended to maintain their nanosheet morphology compared with calcination in the air. …”

“…In this study, three different approaches, i.e. the sol–gel method, precipitation method and hard-template method, were applied to synthesize MgF(2) catalysts with improved stability towards the dehydrofluorination of hydrofluorocarbons (HFCs); the in situ XRD technique was employed to investigate the relationship between the calcination temperature and the crystallite size of precursors to determine optimal calcination temperature for the preparation of the MgF(2) catalysts. …”

“…We attempted to insert guest iron oxide (Fe(x)O(y)) nanoparticles into these films by two different methods: (a) by co-precipitation—where iron precursors are introduced in the synthesis sol before deposition of the silica film—and subsequent oxide production during the film calcination step; (b) by preparing and calcining the silica films first then impregnating them with the iron precursor, obtaining the iron oxide nanoparticles by a second calcination step. …”
