SUMMARY:Claudia Felser, Max Planck Institute for Chemical Physics of Solids, Dresden, Germany
DESCRIPTION:
Topology and Chemistry: From
solid state chemistry to Catalysis
Topology, a mathem
atical concept, recently became a hot and truly transdisciplinary topic in
condensed matter physics, solid state chemistry and materials science. All
200 000 inorganic materials were recently classified into trivial and topol
ogical materials: topological insulators, Dirac, Weyl and nodal-line semime
tals, and topological metals [1]. The direct connection between real space:
atoms, valence electrons, bonds and orbitals, and reciprocal space: bands
and Fermi surfaces allows for a simple classification of topological materi
als in a single particle picture. Around 20% of all inorganic compounds hos
t topological bands, which opens also an infinitive play-ground for chemist
ry [2]. A fingerprint of topological materials is an unusual surfaces state
, which can impact catalysis. We discuss examples of topological catalysis:
hydrogen evolution and oxygen evolution reaction [3].
