The decomposition of surface methoxy on clean and oxygen post dosed Fe(100); control of reaction selectivity

Probing Surface Reaction Mechanisms Using Chemical and Vibrational Methods: Alkyl Oxidation and Reactivity of Alcohols on Transitions Metal Surfaces

“…acetone formation from 2-propoxide bound to Rh (111)-p(2×1)-O. 2 In contrast, the C-O bond in alcohols bound to Mo(110) [23][24][25][26][27] or Fe [28][29][30][31] is readily cleaved. For example, the C-O bond in methoxide breaks below 400 K on Mo (110), resulting in ∼99% nonselective decomposition to surface carbon, hydrogen, and oxygen.…”

Theoretical study on the effective methanol decomposition on Pd(111) surface facilitated in alkaline medium

“…It has also been shown that the decomposition reaction often occurs at low temperatures of around 200 K on the surface of Group VIII metals. For example, studies by means of many experimental techniques such as high resolution electron energy loss spectroscopy (HREELS), temperature programmed desorption and isotopic labeling have shown that methanol decomposition takes place by the O-H bond breaking on Ni(1 1 1) [11,12], Ni(1 1 0) [13,14], Pt(1 1 1) [15], Pd(1 0 0) [18,19], Ru(0 0 1) [20], Fe(1 0 0) [21], Rh(1 1 1) [22,23], and Rh(1 0 0) [24]. A study by static secondary-ion mass spectrometry (SSIMS) on methanol decomposition on Pd(1 1 1) single crystal surface has observed PdOCH þ 3 species which give evidence for the presence of the CH 3 O species [27].…”

“…The adsorption of methanol on metal surfaces has been extensively studied experimentally [4,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The dissociative chemisorption of methanol on metal surfaces by the O-H bond breaking to produce CH 3 O intermediates is commonly accepted as a general phenomenon [26].…”
