Abstract

The subject of catalysis by coinage metals (copper, silver, and gold) comes up increasingly day-by-day. This Special Issue aims to cover the numerous aspects of the use of these metals as catalysts for several reactions. It deals with synthesis and characterization of copper, silver and gold based catalysis, their characterization and use, both for heterogeneous and homogeneous catalysis, and some of their potential applications.

Highlights

Catalysts are materials that allow important reactions to be more selective, faster and require less energy
The observed phenomena cannot be explained only considering the 1–13 nm Ag particle size distributions measured by HRTEM; the existence of Ag species with size < 1 nm, non-visible in HRTEM, and their interaction with the supports, needs to be taken into account
Silver and copper are reported as catalysts, in a new and efficient way, for the cycloaddition of propargyl-substituted dihydroisoindolin-1-one with arylnitrile oxides to produce novel 3,5-disubstituted isoxazoles of the ethyl-2-benzyl-3-oxo-1-((3-arylisoxazol-5yl)methyl)-2,3-dihydro-1H-isoindole-1-carboxylate type [2]

Summary

Introduction

Catalysts are materials that allow important reactions to be more selective, faster and require less energy. Coinage metals (copper, silver, and gold) are often found as important components of most catalysts and are known for their high activity and important properties. The role of sub-nanometric Ag species (on Fe, Mg and Ce modified TiO2 materials) on catalytic CO oxidation is studied by several techniques in [1].
