Catalysis of methane decomposition over elemental carbon

Catalytic performance of carbon nanotubes in H2O2 decomposition: Experimental and quantum chemical study

“…Besides serving as a support, CNTs alone can be used as catalysts for some specific reactions, including methane and NO x decomposition [3,4], oxidative dehydrogenization of aromatic hydrocarbons and alkanes [5,6,7,8,9], oxidation of aniline [10], p-toluidine [11], and benzyl alcohol [12], catalytic wet air oxidation of phenol [13,14] and pcoumaric acid [15,16], aerobic oxidation of cyclohexane [17,18], ozonation of oxalic acid [19,20], selective oxidation of H 2 S [21], and heterogeneous hydroxylation of organics [22]. Nitrogen-doped CNTs were used as basic catalyst in Knoevenagel condensation [23] and CO oxidation [24] reactions.…”

Production of Hydrogen: Photocatalytic Decomposition of Dimethyl Ether over Metal-Promoted TiO<sub>2</sub> Catalysts

“…We assume that the CH 3 O species formed at the metal/TiO 2 interface is much more reactive than that located on TiO 2 . The promoting effect of Pt metals deposited on TiO 2 is generally explained by the better charge carrier separation induced by illumination [12] [13] [42].…”

“…In principle, the decomposition of methane and hydrocarbons seems to be a suitable process, but the carbon formed poisons the catalyst in early phase of the reaction [1]- [3]. More frequently used sources of H 2 are ethanol, me-thanol and formic acid [4] [5].…”

Methane Conversion Assisted by Plasma or Electric Field

“…To avoid operating this regeneration process, many investigations have assessed carbon-based catalysts. Testing of various carbon-based catalysts found that amorphous carbon such as active carbon and carbon black exhibited higher activity than ordered catalysts such as graphite and diamond powder 24) . Furthermore, conversion of methane as high as 70 % can be achieved over a wood char catalyst 25) .…”
