Mg-Al layered double hydroxide (LDH) nanocrystallites with a lateral size less than 9 nm were in situ synthesized within the pore channels of mesoporous silica materials, creating one of the most active heterogeneous base catalysts owing to the high number of active edge sites.

Nitriding of nanocrystalline iron and reduction nitride with gaseous mixtures hydrogen ammonia were studied at 375 °C atmospheric pressure using the chemical potential programmed reaction (CPPR) method coupled in situ XRD. In this paper, a series phase transitions occurring during processes is shown, detailed analysis composition structure material given. The influence variable nitriding on lat...
