INTRODUCTION It is not our intent here to present a comprehensive review of the dynamic behavior of the catalytic oxidation of CO. This reaction is one of the most widely studied in the field of catalysis. A review paper by Engel and Ertl [ l ] has examined the basic kinetic and mechanistic aspects, and a comprehensive paper by Razon and Schmitz [2 ’J was recently devoted to its dynamic behavio...

Chemical reactivity of transition metal clusters toward various molecules in gas phase has been a subject of numerous investigations,1,2 motivated by search of analogues to adsorption mechanisms and reactivity at bulk metal surfaces. However, the full catalytic cycle, involving detection of a product molecule XY, as a result of reaction between reactants X and Y in the presence of the metal clu...

an efficient synthetic method for successful synthesis of amine denderon on sba-15 and related pd (ii) complex has been developed. this modified mesoporous material was characterized by various techniques such as tem, xrd, atomic absorption spectroscopy, n2 adsorption-desorption, and ft-ir. the catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of al...

PtSn-based catalysts are one of the most active materials toward that contribute ethanol oxidation reaction (EOR). In order to gain a better understanding of the Sn influence on the carbon monoxide (principal catalyst poison) and ethanol oxidation reactions in acidic media, a systematic spectroelectrochemical study was carried out. With this end, carbon-supported PtSnx (x = 0, 1/3 and 1) materi...

We report the first experiment carried out on an in situ setup, which allows for detection of CO(2) from catalytic CO oxidation close to a model catalyst under realistic reaction conditions by the means of planar laser-induced fluorescence (PLIF) in the mid-infrared spectral range. The onset of the catalytic reaction as a function of temperature was followed by PLIF in a steady state flow react...

In this study, TiO2 thin film photocatalyst on carbon fibers was used to synthesize ultra-long single crystalline Pt nanowires via a simple photoreduction route (thermally activated photoreduction). It also acted as a co-catalytic material with Pt. Taking advantage of the high-aspect ratio of the Pt nanostructure as well as the excellent catalytic activity of TiO2, this hybrid structure has the...
