B. Delmon Honor Special issue
No full textThis special issue of Applied Catalysis A presents a collection of papers honouring Professor Bernard Delmon on the occasion of his 80th birthday. The objective was to compile an issue comprising contributions from researchers who have worked with Professor Delmon in our laboratory whether as PhD students, post-docs or visiting professors - namely researchers who have closely collaborated with him and who were taught and inspired by him

The boiling pot at oxide surfaces
No full textThe contribution concerns the crucially important layer near the catalyst surface (here, called Z* for convenience) that turns out to be often thicker than usually assumed. Special experiments [M. Alifanti, J. Kirchnerova, B. Delmon, D. Klvana, Appl. Catal. A 262 (2004) 167] indicate that Z* could possess electrochemical features, more precisely promote polarization effects. Measurements of thermodynamical activity and introduction of foreign species in Z* could lead to progress in fundamental interpretations. Examples are given and suggestions made, concerning the use of polarizable dopes in the gas phase or in the catalyst (possibly containing two or several phases), or the application of physical activation techniques. Some speculations are proposed concerning new advances. (C) 2006 Elsevier B.V. All rights reserved
How To Reduce the Greenhouse-effect, and a Few Other Questions Concerning Catalysis
No full textAll those active in catalytic science and technology know that catalysis has a paramount role to play for environmental protection. But do we discern the most important problems? Just by accident, the author of this chronicle presented more or less impromptu some remarks at a meeting [1] and thereafter talked on the same topic in front of different audiences. He discovered that what he believed to be more or less obvious to his colleagues actually opened to them some new horizons and induced animated discussions (not deprived of passion in some cases!). This is the reason why he takes the risk to present this publication. He wishes to underline that the facts and figures he cites are the best available ones. He has noticed that, although scientifically grounded, these facts and figures may hurt some readers. He has been himself very unhappy to discover the results of some comparisons. Factual data cannot be denied. The problem is to find socially acceptable ways to improve the situation described by these facts
Deactivation of carbon-supported platinum catalysts during oxidations in aqueous media
No full textThe platinum catalyzed selective oxidn. reactions of ethanol and methyl-a-D glucopyranoside (MGP) were studied in combination with catalyst characterization using Transmission Electron Microscopy (TEM), CO chemisorption, cyclic voltammetry and open-circuit potential measurements. Some evidence for catalyst deactivation by over-oxidn., leaching, platinum particle growth and site coverage is presented. The absence of deactivation obsd. for ethanol can be attributed to the higher reducing ability of ethano
