نویسندگان
چکیده
The theory of diffusion and the principal methods of determining surface diffusion coefficients are presented and their strengths and weaknesses discussed. A summary of major experimental results for diffusion of metallic and non-metallic adsorbates on metal surfaces is given and areas of agreement and disagreement between various measurements are discussed. A brief overview of principal conclusions, problem areas and future directions concludes the review. This review was received in its present form in October 1989. 0034-4885/90/070917 + 86314.00 @ 1990 IOP Publishing Ltd 917

Transport of adsorbates at metal surfaces: from thermal migration to hot precursors
Theoretical aspects and evolution of surface diffusion studies are discussed with an emphasis on non-metallic adsorbates at metal surfaces. A survey of the existing literature is presented with the main experimental results tabulated. (The tables and their updates are available online at http://ipent.ep ̄.ch/gr_kern/jv_barth/ SD_tables.html) Conception, theoretical and experimental work on trans...
متن کاملAdsorbate diffusion on transition metal nanoparticles.
Diffusion of adsorbates on transition metal nanoparticles is a precursor process for heterogeneously catalyzed reactions, and as a result, an atomistic understanding of the diffusion mechanism is very important. We systematically studied adsorption and diffusion of atomic and diatomic species (H, C, N, O, CO, and NO) on nanometer-sized Pt and Cu nanoparticles with different sizes and shapes usi...
متن کاملFast diffusion of water nanodroplets on graphene.
Diffusion across surfaces generally involves motion on a vibrating but otherwise stationary substrate. Here, using molecular dynamics, we show that a layered material such as graphene opens up a new mechanism for surface diffusion whereby adsorbates are carried by propagating ripples in a motion similar to surfing. For water nanodroplets, we demonstrate that the mechanism leads to exceedingly f...
متن کاملPhotochemistry on metal nanoparticles.
The photochemistry of small molecules on well-defined metal surfaces has been the subject of intense research for more than three decades.1 This field is of interest because it rests on the superposition of two influences. On one hand, new reaction channels can become possible by electronic excitation, which are usually not accessible by thermal activation. On the other hand, compared to molecu...
متن کاملWork function changes induced by charged adsorbates: origin of the polarity asymmetry.
A theoretical analysis of charged adsorbates on a metal surface reveals a pronounced polarity asymmetry between electropositive and electronegative species, thus reproducing a well known but so far not properly understood experimental fact. For ionic adsorbates on metal surfaces, we analyze the several, often cancelling, terms that contribute to the change of the interface dipole and, hence, to...
