Carbon structures comprising sp 1 chains (e.g., polyynes or cumulenes) can be synthesized by exploiting on-surface chemistry and molecular self-assembly of organic precursors, opening to the use of the full experimental and theoretical surface-scienc

Single Atom Catalysts (SAC) trapped in defective and nitrogen-doped graphene supported on metal substrates

Autor: Laura Trovato, Cristiana Di Valentin, Anu Baby

Publikováno v: Carbon. 174:772-788

Single Atom Catalysts (SAC) in graphene have been recently gaining more and more attention. They are usually non-noble transition metal (TM) adatoms getting trapped at the carbon vacancies during the fabrication of the graphene layer, which then act

Operando visualization of the hydrogen evolution reaction with atomic-scale precision at different metal–graphene interfaces

The development of catalysts for the hydrogen evolution reaction is pivotal for the hydrogen economy. Thin iron films covered with monolayer graphene exhibit outstanding catalytic activity, surpassing even that of platinum, as demonstrated by a metho

High Potassium Concentrations Nested in Epitaxial Monolayers of a Flexible Lander-Type Molecule on Ag(111)

Autor: Guido Fratesi, Roman Forker, Falko Sojka, Anu Baby, Torsten Fritz, Tino Kirchhuebel, Felix Otto

The structural, electronic, and optical properties of organic adlayers can be tuned to a large extent by incorporating metal atoms. Naturally, the tunability of those properties is limited by the thermodynamic stability of the intercalated phases obt

We investigated the adsorption of corannulene (C20H10) on the Ag(111) surface by experimental and simulated scanning tunneling microscopy (STM), X-ray photoemission (XPS), and near-edge X-ray absorption fine structure (NEXAFS). Structural optimizatio
