“…Mou et al reported that such catalysts display higher catalytic activity in ethylbenzene dehydrogenation and also slower deactivation compared to impregnated catalysts [2]. Similar conclusions were reached by Xiao et al for the selective reduction of NO by propylene [3].…”

“…[8] Constrastingly, Mou and co-workers found that physically mixed samples have lower rates of deactivation and higher catalytic activities than solution impregnation samples in both fresh and regenerated tubular MCM-41-supported MoO 3 catalysts for the ethylbenzene dehydrogenation reaction. [9] The preparation of oxide-supported mesoporous catalysts includes two separate steps of inclusion and calcination. Early in 1990, Xie and Tang reported on the spontaneous monolayer dispersion of salts and oxides on the surface of supports after solid-state grinding and, in some cases, preheating.…”

Solid‐state grinding is a simple and effective method to include guest species into the channels of ordered mesoporous materials with a different degree of filling. After calcination, a monolayer or several monolayers of guest species can not only form highly dispersed oxide species and other surface species on the hosts whether the template is occluded in the channels or not, but the guest species can also fill the mesoporous channels in the host and thus lead to nanowires or nanoarrays. Solid‐state salt inclusion is faster and more convenient than other inclusion routes. The absence of a solvent not only saves the time otherwise needed for evaporation but also leads to a higher degree of filling through a simple inclusion step as the void space in the pores is not occupied by the solvent. Also, the lack of competitive adsorption of solvent molecules enhances the interaction between the guest species included and the silica wall, which facilitates the high dispersion of oxide species. However, host–guest interactions that are too strong may disturb the self‐crystallization of guest species in the mesopores leading to imperfect nanocasting of the mesostructure.

“…The use of many catalysts, which mainly consist of Fe and K oxides containing one or more promoters (Mg, Ce, Cr, Mo, V, Ca), and acid solids such as zeolites and metal phosphates, has been reported. There is a continuous search for more efficient catalysts and reaction conditions; some of the new catalysts formulations proposed also involving iron oxides [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Dehydrogenation of ethylbenzene on alumina-pillared Fe-rich saponites

et al. 2005

An iron-rich saponite, variety griffithite, from Griffith Park, California, USA, has been pillared with hydroxy-aluminium oligomers, giving rise to very crystalline layered solids with basal spacings of 17.4-17.7 a˚and specific surface areas of 233-293 m 2 /g. The catalytic performance of these pillared solids, and also of the natural griffithite, all after calcination at 773 K, in the dehydrogenation of ethylbenzene was evaluated. The catalytic behaviour strongly depends on the acid properties developed in the solids by the pillaring treatment.
