Inside Back Cover: Activity of Atomically Precise Titania Nanoparticles in CO Oxidation (Angew. Chem. Int. Ed. 24/2019)

Abstract

Understanding how properties evolve in atomically precise nanoparticles as their size changes atom by atom is critical for designing functional nanomaterials. In their Communication on page 8002 ff., Y.‐X. Zhao, X.‐L. Ding and co‐workers show the superior oxidative activity of stoichiometric (TiO2)nO− over other clusters of (TiO2)nOm− (m≠1) has been experimentally identified even when the cluster dimensions increase to n=60, indicating that each atom still counts in the chemical behavior of titania nanoparticles composed of approximately 180 atoms.

Heterojunction Engineering of Multinary Metal Sulfide‐Based Photocatalysts for Efficient Photocatalytic Hydrogen Evolution

“…In addition to the PHE via water splitting, the understanding of the mechanism of photocatalytic degradation is also important and can provide efficient route to realize the PHE via overall water splitting. [ 97,98,99 ] The photocatalytic degradation of mechanism of MS photocatalysts has been studied by several researches [ 100,101,102,103 ] and the corresponding specific process has been summarized by Pingmuang et al. [ 96 ] Specifically, as shown in Figure 1f–h, the development stage of photogenerated degradation organics technique can be concluded as direct degradation, dye photosensitization, and photocatalytic degradation of dyes by the radicals from the photogenerated charges.…”
