Synthesis of nanocrystalline NiO/doped CeO2 compound powders through combustion of citrate/nitrate gel

Citrate–nitrate auto-combustion synthesis of perovskite-type nanopowders: A systematic approach

“…Regarding FE samples, at low F/O ratios crystal size is 120 nm as well, although it was not possible to obtain a crystal size trend with F/O since, by increasing F/O ratio, the perovskite structure changes from cubic to a less symmetric structure, which was not possible to identify properly, as already discussed in the previous paragraph. From the above results it is possible to calculate the mean agglomeration degree (particle size/crystal size) for CE and CO samples which is 1.5-2 crystals per particle at F/O = 0.4 for all the chemical compositions examined and increases slightly to 3-4 [55][56][57] Moreover, a volcano trend of the crystal size with fuel content is reported in literature, 53,58 although this trend could be interpreted as the overall result of the F/O and C/M variation.…”

Catalytic Performance of Ce1−x Ni x O2 Catalysts for Propane Oxidative Steam Reforming

“…Stoichiometric amounts of (NH 4 ) 2 Ce(NO 3 ) 6 , Ni(NO 3 ) 2 Á 6H 2 O and C 2 H 6 N 4 O 2 (oxalyldihydrazide, as fuel) in aqueous solution were mixed in a borosilicate dish and heated at 350°C to give a flaming combustion [15,16]. The chemical reactions occurring in the combustion process can be written as follows: …”

Synthesis of CuO, Cu and CuNi alloy particles by solution combustion using carbohydrazide and N-tertiarybutoxy-carbonylpiperazine fuels

“…Combustion synthesis is an effective method for the preparation of homogeneous, finely dispersed crystalline uni-and multicomponent oxides [1][2][3][4][5][6][7][8] as well as metals and alloys of uniform composition and size [9,10]. This method is quick, straightforward and less time consuming without the involvement of any intermediate preparative steps.…”

“…This method is quick, straightforward and less time consuming without the involvement of any intermediate preparative steps. Combustion synthesis has been used extensively for the preparation of different classes of materials such as oxides, nitrides, carbides, complex oxides, metals and alloys which are used for diverse applications [1][2][3][4][5][6][7][8][9][10]. Several novel procedures and modifications have been introduced into combustion synthesis to obtain materials with desired properties for a variety of applications.…”
