Adsorption and reactions of ethanol and ethanol–water mixture on alumina-supported Pt catalysts

Towards an improved process for hydrogen production: the chemical-loop reforming of ethanol

“…) 52,38. Figures 5(A-C) show a strong band at 3252 cm -1 that may be assigned to the OH stretching of ethanol H-bonded to the surface, which also was observed over the stoichiometric CoFe 2 O 4 ferrospinel in our previous paper 38.…”

“…[50][51][52][53][54] However, the species formed with increasing temperatures are more related to the surface chemistry of each compound. According to the literature, ethanol adsorbs on the surface mainly as an ethoxide, formed from the scission of the O-H bond.…”

Electro-oxidation of methanol and ethanol on carbon-supported Pt catalyst at intermediate temperature

“…Partly, ethanol oxidation at intermediate temperature may proceed similarly to that at room temperature, as stated above. In addition, dehydrogenation of ethanol occurs at intermediate temperature [42,43].…”

Improved ethanol steam reforming on Rh/Al2O3 catalysts doped with CeO2 or/and La2O3: Influence in reaction pathways including coke formation

“…According to the literature [23][24][25], the reaction mechanism on supported noble metal catalysts involves different steps: (i) ethanol dissociative adsorption, (ii) ethanol dehydrogenation to acetaldehyde and acetyl species, and (iii) acetaldehyde decomposition to CO and methane, or (iv) oxidation of dehydrogenated species to acetate species by addition of support-bound hydroxyl groups. In addition to these reactions, subsequent reactions such as water gas shift (WGS) and steam reforming of methane (SRM) promote the production of H 2 from the CO and methane previously produced.…”
