Spectroscopic identification of alkoxide, aldehyde, and acyl intermediates in alcohol decomposition on Pd(111)

Chemistry of Ethylene Glycol on a Rh(100) Single‐Crystal Surface

“…Several surface science studies on the reaction and decomposition of the related single alcohol ethanol on group VIII metals are available, for example Ni, [2][3][4][5] Pd, [6][7][8][9] Ir, [10] Pt, [4,[11][12][13][14][15][16][17] and Rh, [18][19][20][21] but research on ethylene glycol is scarce (e.g., Ni, [22] Pt, [4,16,17] and Rh [23] ). The surface chemistry of ethanol provides insight into what may be expected for ethylene glycol.…”

Ethanol Adsorption, Decomposition and Oxidation on Ir(111): A High Resolution XPS Study

“…[1][2][3][4][5][6][7][8][9][10][11][12] The nature of the metal determines whether CÀC or CÀO bond breaking occurs first. Different reaction intermediates have been identified, including C 2 H 5 O ad , [9] acetaldehyde [9] and acetyl. [4,9,13] In some of these studies high-energy resolution X-ray photoemission spectroscopy (XPS) was used to elucidate the identity of surface intermediates and determine adsorbate coverage.…”

Hydrogen generation by photocatalytic reforming of potential biofuels: Polyols, cyclic alcohols, and saccharides

“…In order to understand the mechanism of hydrogen production, the reactivity pattern of alcohol on pure TiO 2 and Pd surfaces were used to gain insights into the catalytic processes. Although most of the decomposition studies were carried out on the Pd model single crystal surfaces in UHV conditions [34][35][36][37][38], we have shown that methanol, ethanol and propanol photocatalytic reaction products mimic the decomposition pattern on the well-defined Pd metal surfaces [21,39]. Studies carried out by Griffin et al on the decomposition of ethylene glycol on Pd showed similar characteristics to methanol decomposition [40].…”
