Thermocatalytic decomposition of methane over activated carbons: influence of textural properties and surface chemistry
TL;DR: In this article, the authors used activated carbons with different textural properties and surface chemistry to study the influence of these properties on the efficiency of methane decomposition, and found that the initial reaction rate of decomposition is related to the surface chemistry of the catalyst, in particular to the concentration of oxygenated groups.
Journal ArticleDOI
Cherry stones as precursor of activated carbons for supercapacitors
Mara Olivares-Marín,J. A. Fernández,María Jesús Lázaro,C. Fernández-González,Antonio Macías-García,Vicente Gómez-Serrano,Fritz Stoeckli,Teresa A. Centeno +7 more
TL;DR: In this paper, it was shown that cherry stones-wastes can be recycled as activated carbons for electrode material in supercapacitors, which lead to capacitances at low current density as high as 230 F g−1 in 2 M H2SO4 aqueous electrolyte and 120 F g −1 in the aprotic medium 1 M (C2H5)4NBF4/acetonitrile.
Journal ArticleDOI
Hydrogen production by thermo catalytic decomposition of methane on Ni-based catalysts: influence of operating conditions on catalyst deactivation and carbon characteristics
TL;DR: In this paper, the authors used a commercial Ni-based catalyst to study the characteristics of the carbon produced and the catalyst deactivation mechanism in a fixed bed reactor at different operating conditions, and they showed that the deposited carbon appeared either as large filaments a few nanometres in diameter emerging from Ni particles or as uniform coatings.
Journal ArticleDOI
Pt-Richcore/Sn-Richsubsurface/Ptskin Nanocubes As Highly Active and Stable Electrocatalysts for the Ethanol Oxidation Reaction
Rubén Rizo,Rosa M. Arán-Ais,Elliot Padgett,David A. Muller,María Jesús Lázaro,José Solla-Gullón,Juan M. Feliu,Elena Pastor,Héctor D. Abruña +8 more
TL;DR: The synthesis, characterization, and electrochemical behavior of cubic Pt-Sn nanoparticles are described, finding that Sn dissolves from the outer part of the shell after potential cycling, forming a ∼0.5 nm Pt skin, which is responsible for the high activity and stability.
Journal ArticleDOI
Analysis of the strategies for bridging the gap towards the Hydrogen Economy
TL;DR: In this article, the current situation of the three main fields of the Hydrogen Economy: production, distribution and uses are analyzed and some considerations and suggestions for action are provided, and the strategy for introduction should be planned not in terms of confrontation with the other energy vectors but in term of convergence and synergies search.
