“…Applications of thiol-stabilized AuNPs in catalysis include the asymmetric dihydroxylation reactions, [94] carboxylic ester cleavage, [95] electrocatalytic reductions by anthraquinone functionalized AuNPs, [96] and particle-bound ring opening metathesis polymerization. [97] These catalytic applications have in common the exploitation of the carefully designed chemical functionality of the ligand shell, rather than the potential catalytic activity of a nanostructured clean metal surface. One of the most prominent potential long-term applications for AuNPs and clusters is the development of new, ultimately small electronic devices.…”

Carbon nanotubes constitute a novel class of nanomaterials with potential applications in many areas. The attachment of metal nanoparticles to carbon nanotubes is new way to obtain novel hybrid materials with interesting properties for various applications such as catalysts and gas sensors as well as electronic and magnetic devices. Their unique properties such as excellent electronic properties, a good chemical stability, and a large surface area make carbon nanotubes very useful as a support for gold nanoparticles in many potential applications, ranging from advanced catalytic systems through very sensitive electrochemical sensors and biosensors to highly efficient fuel cells. Here we give an overview on the recent progress in this area by exploring the various synthesis approaches and types of assemblies, in which nanotubes can be decorated with gold nanoparticles and explore the diverse applications of the resulting composites.

“…They found much higher turnover frequencies for the surfacebound Ru catalyst compared to the same catalyst in bulk solution. [132] This phenomenon is tentatively attributed to the favorable orientation of the Ru species, which facilitates their interactions with the growing polymer chain. Most mechanistic studies in SAMs, however, report diminished reactivity (vide infra), due to partially blocked access of an external reagent to the monolayer-embedded reaction center.…”

“…[8] In previous studies we employed SAMs of various thiols for a number of applications such as direct crystallization or polymerization catalysis. [9] The use of thiol monolayer surfaces on gold has been extended by us to the use of thiol coated gold colloids. This has opened new dimensions in the chemistry of protected surfaces as colloids show a similar behavior as molecules, that is they can be precipitated or redissolved.…”

Gold-coated glass slides have be patterned by using self-assembled monolayers (SAM) of alkane thiols. Through the use of a special thiol terminated with a styrene monomer, microstructures of 5 to 10 microm width and 70 A height have been formed on the surface by graft polymerization of styrene. These patterned gold slides have then been used to template the precipitation of thin titania films from ethanolic solutions of titanium isopropoxide to create microstructured architectures in the film. Plasmon resonance spectra have established the presence of different steps in the process and have been used to follow the kinetics of the precipitation of titania on the surface. The structured TiO2 films have been characterized by scanning electron microscopy.
