Generation of CH2 species: thermal and photo-induced dissociation of CH2I2 on Rh(111) surface

Adsorption and reactions of CH2I2 on Ru(001) surface

“…5C ). of Ru(001) resembles that of Rh(111) [18,19]. On Pd(100) we found a larger amount of C 2 H 4 An interesting feature of the CH 2 I 2 /Ru(001) system is the formation of CH 3 I in the desorbing besides CH 4 [17], while on Cu surfaces only C 2 H 4 was produced without CH 4 [23].…”

“…In the UP spectra of polycrystalline Ni and Co, following the dissociative adsorption of CH 2 I 2 , a [18] surfaces. Much less change (Dw#−0.1 eV ) was obtained for Cu(100) surface [23].…”

Thermal chemistry of diiodomethane on Ni(110) surfaces II. Effect of coadsorbed oxygen

“…On clean metals, methylene chemisorbed species typically react via coupling to ethene, dehydrogenation to carbon, and hydrogenation to methane steps [22][23][24][25][26][27][28][29]. In our accompanying article, the first half of this report, additional hydrocarbon chain growth steps were detected on clean Ni(1 1 0) surfaces as well [30].…”

Bond Forming Reactions Involving C1 Moieties: Late Versus Early Transition Metal Surfaces

“…Methane production is seen in both cases, a clear indication of the potential for vanadium surfaces to promote certain hydrogenation reactions. Similar chemistry has been documented on the surfaces of single-crystals of other transition metals, both for methylene groups on Cu(100) [21], Cu(110) [22], Ag(111) [23], Ni(100) [24], Ni(110) [25], Pd(100) [26], Pt(111) [27][28][29], Rh(111) [30,31], Ru(001) [32,33], Mo(100) [34,35], and Mo(110) [36], and for methyl moieties on Cu(100) [37], Cu(111) [37,38], Cu(110) [22,37], Ni(100) [24,39], Ni(111) [40,41], Ni(110) [42], Pd(100) [43,44], Pt(111) [27,28,45,46], Rh(111) [47,48], Ru(001) [49], Mo(100) [35,50], and Mo(110) [51]. Ethylene production via coupling of methylene is also seen in Fig.…”
