Sol–gel synthesis of V2O5–SiO2 catalyst in the oxidative dehydrogenation of n-butane

Silicates characterization as potential bacteriocin-carriers

“…The position and shape of these bands undergo very slight changes with later treatments. The high intensity adsorption band at 1092 cm − 1 , corresponding to Si-O asymmetric stretching characteristic of silica gels, and a shoulder at 1199 cm − 1 , are indicative of a degree of disorder in the silica network (Murgia, Farfán Torres, Gottifredi, & Sham, 2006). The shoulder observed at 960 cm − 1 (Fig.…”

Density functional theory study of the oxidative dehydrogenation of propane on the (001) surface of V2O5

“…Catalysts contain either dispersed vanadia or particles of V 2 O 5 are among the most active selective oxidative dehydrogenation catalysts and many papers and reviews have been published dealing with the preparation of vanadium based catalysts and their related properties [10,13,15,[27][28][29][30][31][32][33][34]. From experimental studies, it was found that both monovanadate and polyvanadate units can be formed on the support depending on the vanadium content [35,36].…”

The beneficial utilization of natural zeolite in preparation of Cr/clinoptilolite nanocatalyst used in CO2-oxidative dehydrogenation of ethane to ethylene

“…Regarding to the abundance and lower 15 cost of light alkanes, upgrading them to the corresponding alkenes 16 may become interesting processes to meet future demands for 17 light olefins [4], particularly for ethylene. As an important raw 18 material in the modern chemical industry, ethylene is currently 19 produced by steam cracking and fluid catalytic cracking (FCC) 20 [5].…”
