Metal cluster complexes exhibit many useful catalytic, optical, and other potentially useful properties for materials science applications, and many impressive advances have been made with respect to their synthesis. These metrics are regularly updated to reflect usage leading up to the last few days. Please reconnect. T. M. Bernhardt, Gas-phase kinetics and catalytic reactions of small silver and gold clusters, Int. In addition, based on computational modeling of SMCs, theoretical calculations corroborated well with experimental results, providing in-depth insights into the structure–property relationship for SMCs in catalysis. Molecular metal atom clusters or atomic species are comprised of at least two or more metal atoms attached to each other, notwithstanding being bonded to other nonmetals. Different from isolated metal atoms and large metal nanoparticles (NPs), supported metal clusters (SMCs) possess distinct geometric and electronic structures and thus exhibit enhanced activity and designated selectivity in catalysis.

Files available from the ACS website may be downloaded for personal use only. Different from isolated metal atoms and large metal nanoparticles (NPs), supported metal clusters (SMCs) possess distinct geometric and electronic structures and thus exhibit enhanced activity and designated selectivity in catalysis. The development of new sophisticated synthetic techniques has led to enormous progress in the synthesis of this diverse class of compounds. In particular, upon entrapping an otherwise unstable metal cluster into a carbon cage, the so-called endohedral clusterfullerenes fulfil the mutual stabilization of the inner metal cluster and the outer fullerene cage with a specific isomeric structure which is often unstable as an empty fullerene.

Subsequently, the applications of SMCs in important catalytic reactions based on recent studies are discussed, including aerobic oxidation, hydrogenation, dehydrogenation, water–gas shift (WGS) reaction, and photocatalytic reactions. Magnetic properties of alkali metal clusters in zeolite cages The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online. the Altmetric Attention Score and how the score is calculated.

From that point forward, metal clusters of different metals, for example, Au, Ag, Cu, Pt, Pd, and so forth, have been developed and examined by molecular chemists. Therefore, the aim of this book is to form a comprehensive introduction to this very important area of inorganic chemistry. In particular, the importance of the cluster size-effect and metal–support interactions in determining the catalytic performance of SMCs is highlighted.
