“…The use of noble metals, particularly Pt and Rh as active species for catalytic reforming of the methane processes attract much interest because they lead to excellent results. However, they are very expensive (Hickman & Shimidt, 1992;Monnet et al, 2000;Fathi et al, 2000). Through scientific research was discovered that Ni when tested under reaction conditions of reforming of methane process, the catalytic performance and the quality of the product output are equivalent to the final results obtained by noble metals such as Pt and Rh.…”

“…Pt, Rh, Ni are among the most effective catalysts. Pt supported on silicon nitride [9,65] shows very good stability in comparison to Pd/alumina during partial oxidation (flow rate: 1.6 l/min; O 2 /CH 4 /N 2 :2/1/10) at 900°C. As can be seen in Fig.…”

“…In the case of Rh such behaviour was not observed since, during reaction, the metallic particles are coated by the support [65]. In reaction conditions the presence of Rh must catalyze decomposition of the support that recovers the active phase and renders the catalyst ineffective.…”

Aires, F. J. Cadete Santos Bertolini, J. C.Silicon nitride has very good thermal and chemical stability, as well as high thermal conductivity compared to oxide materials, which are commonly used as catalyst supports. In exothermic reactions working at high temperature, this facilitates heat transfer and thus limits the formation of local hot spots, which are often responsible for structural modification of the support in addition to sintering of active phases. However, it is only recently that this material has been considered for application as a catalyst support for high temperature reactions. It is now established that silicon nitride can be a good support for catalytically active phases. Its range of application is continually expanding (e.g., partial/total oxidation of methane, hydrogenation and dehydrogenation reactions, photocatalysis, base catalysis, etc.)

Gas phase ammonolysis of volatile metal chlorides at elevated temperatures is a favorable way to produce nitride or oxynitride nanopowders. Their composition as well as the physico-chemical properties is determined by reaction temperature, molar ratio of the reactants and the residence time of the gases in the reaction zone. Both single and multi component powders can be obtained. Typical particle sizes are in the range of 50 to 350 nm. The specific surface can reach values up to 300 m2/g. Microporous analysis revealed the presence of pores with a diameter between 0.6 and 0.7 nm in amorphous silicon nitride. The powders can be used, depending on the characteristics, as catalyst or basic catalyst support. The paper gives an overview about vapor phase synthesis of single and multi component nitrides as well as the use of amorphous silicon nitride as a basic catalyst support for dehydrogenation of propane.
