Catalytic performance of nanostructured iron oxides synthesized by thermal decomposition technique

Kinetics of CO oxidation on palladium using microkinetics coupled with reaction route analysis

“…Among gas phase reactions, CO oxidation is an important reaction and is used in many processes such as water gas shift reaction (Ratnasamy and Wagner, 2009), automobile emission gas abatement (Farrauto and Heck, 1999). This reaction has been studied on various metal surfaces such as platinum (Pt) (Engel and Ertl, 1979), palladium (Pd) (Satsuma et al, 2013), rhodium (Rh) (Oh et al, 1986); (Bunluesin et al, 1995), copper (Cu) (Huang and Tsai, 2003), iridium (Engel and Ertl, 1979) and many metal oxides such as iron oxide (El-Sheikh et al, 2009;Halim et al, 2007;Liu et al, 2010;Tripathi et al, 1999), ceria (Bunluesin et al, 1995(Bunluesin et al, ,1996Dong et al, 1999;Oh and Hoflund, 2006;Yao and Yao, 1984;Zhu et al, 2007), zirconia (Satsuma et al, 2013;Faticanti et al, 2005) alumina (Cortes et al, 2007;Ivanova et al, 2010;Zorn et al, 2011), titania (Dong et al, 1999;Satsuma et al, 2013;Zhu et al, 2007).…”

Highly crystalline superparamagnetic iron oxide nanoparticles (SPION) in a silica matrix

“…Consequently, preparation of the magnetic nanoparticles requires several tasks, such as control of the size and size distribution of the particles, control of the morphology and crystallinity, and prevention of the agglomeration. Different preparation methods have been developed in order to obtain desirable samples and physical properties: hydrothermal, sol-gel, solvothermal, mechanochemical, polyol process, co-precipitation, template, thermal decomposition, spray pyrolysis, chemical vapour deposition, carbothermal reduction, electro-precipitation, microwave plasma synthesis, ␥-irradiated water-in-oil microemulsion, melt quench technique, microemulsion and reverse microemulsion technique [1,48,59,62,68,70,[73][74][75][76][77][78][79][80]. Among them the sol-gel method has been shown to be very useful for preparation of iron oxide nanoparticles dispersed in an amorphous silica matrix.…”

Nanosized spinel oxide catalysts for CO-oxidation prepared via CoMnMgAl quaternary hydrotalcite route

“…Catalytic oxidation of CO into CO 2 is considered to be a good route for the reduction of the toxic effects of CO emission in motor engines and other industrial processes [1]. Supported noble metals are generally considered as efficient catalysts for CO oxidation [2,3].…”
