This book covers recent advances in the field of surface functionalized metal catalysts. It not only explores novel catalysts based on metal nanoparticles immobilized on functionalized supports, but also provides an overview of the latest developments in the study of the influence of capping ligands on metal nanoparticle catalysis. Catalysis with surface functionalized metallic systems is attracting significant interest due to the possibility to precisely control the reactivity of surface active sites. Controlling the synthesis, characterization and application of these catalysts offers new possibilities to classical heterogenous catalysis.
