“…Continuous increase in fuel consumption in the energy sector, in various branches of the chemical, petrochemical industry and transport leads to an increase in the volume of harmful substances entering the atmosphere. This is becoming more urgent due to the toughening of the requirements to the quality of the produced base and raw intermediate products of the petrochemical industry [1][2][3][4]. Therefore, studies aimed at developing of various catalysts for the complex treatment of gas emissions of industry, as well as catalysts that work effectively in the field of synthesis-gas production under more favorable conditions, are strategically important [5][6][7][8][9].…”

“…It is known that there are four steps in methane dissociation to surface CH* and C* species, as expressed in Equations (1-4), which are very fast on transition metal surfaces, such as Ni, Ru and Pt [42][43][44][45]. Thus, the reactions of C* and CH* with surface oxygen or OH* to form CO and H 2 are mainly considered here to find out how H 2 O and TiO 2 are involved in the steam reforming or oxidizing reactions of methane [2-4, 18,24] as expressed in Equations (5-8): Under dry atmosphere…”

First principles study on methane reforming over Ni/TiO2(110) surface in solid oxide fuel cells under dry and wet atmospheres

Understanding the carbon-tolerant mechanisms from a microscopic view is of special importance to develop proper anodes for solid oxide fuel cells. In this work, we employed density-functional theory calculations to study the CH 4 reaction mechanism over a Ni/TiO 2 nanostructure, which experimentally demonstrated good carbon tolerance. Six potential pathways for methane reforming reactions were studied over the Ni/TiO 2 (110) surface under both dry and wet atmospheres, and the main concerns were focused on the impact of TiO 2 and Ni/TiO 2 interface on CO/H 2 formation. Our calculations suggest that the reaction between carbon and the interfacial lattice oxygen to form CO* is the dominant pathway for CH 4 reforming under both dry and wet atmospheres, and intervention of steam directly to oxidize C* with its dissociated OH* group is less favorable in energy than that to wipe off oxygen vacancy to get ready for next C* oxidation. In all investigated paths, desorption of CO* is one of the most difficult steps. Fortunately, CO* desorption can be greatly promoted by the large heat released from the previous CO* formation process under wet atmosphere. H 2 O adsorption and dissociation over the TiO 2 surface are found to be much easier than those over Ni, yttria stabilized zirconia (YSZ) and CeO 2 , which should be the key reason for the greatly depressed carbon deposition over Ni-TiO 2 particles than traditional YSZ-Ni and CeO 2 -Ni anode. Our study presents the detailed CO* formation mechanism in CH 4 reforming process over the Ni/TiO 2 surface, which will benefit future research for exploring new carbon-tolerant solid oxide fuel cell anodes.
