Chemical Processes on Solid Surfaces

Nobel Prize® and the Nobel Prize® medal design mark are registered trademarks of the Nobel Foundation 1 Introduction The Nobel Prize in chemistry for 2007 is awarded to Gerhard Ertl for his thorough studies of fundamental molecular processes at the gas-solid interface. When a small molecule hits a solid surface from a gas phase there are a number of possible outcomes. The molecule may simply ei...

Acid–Base Cooperative Catalysis for Organic Reactions by Designed Solid Surfaces with Organofunctional Groups

This chapter deals with acid–base bifunctional heterogeneous catalyst surfaces with organofunctional groups. One of the most important issues for bifunctional heterogeneous catalysis is the coexistence of incompatible catalytic species, such as acid and base, nearby on a same solid particle surface. In nucleophilic reactions, acid–base bifunctional catalysts enable the activation of both nucleo...

Clusters, surfaces, and catalysis.

The surface science of heterogeneous metal catalysis uses model systems ranging from single crystals to monodispersed nanoparticles in the 1-10 nm range. Molecular studies reveal that bond activation (C-H, H-H, C-C, CO) occurs at 300 K or below as the active metal sites simultaneously restructure. The strongly adsorbed molecules must be mobile to free up these sites for continued turnover of re...

Silica sol as grouting material: a physio-chemical analysis

At present there is a pressing need to find an environmentally friendly grouting material for the construction of tunnels. Silica nanoparticles hold great potential of replacing the organic molecule based grouting materials currently used for this purpose. Chemically, silica nanoparticles are similar to natural silicates which are essential components of rocks and soil. Moreover, suspensions of...
