Electron beam-induced demetallation of Fe, Co, Ni, Cu, Zn, Pd, and Pt metalloporphyrins: insights in e-beam chemistry and metal cluster formations

By operando high-resolution transmission electron microscopy, we show that slow secondary electrons from the specimen can demetallate metalloporphyrins. This general approach allows study of the dynamics of various single metal atoms and metal clusters.

Anti-Arrhenius passage of gaseous molecules through nanoporous two-dimensional membranes

Temperature variations reveal a gating effect on molecular permeation across two-dimensional membranes. The reason appears to be adsorption–desorption equilibria on the membrane surface.

A model study of ceria–Pt electrocatalysts: stability, redox properties and hydrogen intercalation

The surface phase of Pt-supported ceria nanoparticles can be controlled by electrochemical potential and by nanoparticle size. Pt-supported ceria nanoparticles accommodate H at the Pt/ceria interface and suppress the hydrogen evolution reaction on Pt(111).

In situ scanning tunneling microscopy studies of carbonate-induced restructuring of Ag-decorated Cu(100) electrodes

AgCu bimetallic model catalysts were prepared by electrodeposition of Ag submonolayers on Cu(100) in sulphuric acid and studied by in situ STM. Electrolyte exchange to bicarbonate solution results in a carbonate-induced Ag island restructuring.

About this collection

Recognising that physical chemistry stands at the centre of efforts to obtain a deeper understanding of materials and molecular processes involved in energy transformation that hold the keys to future technology innovation and development, the DBG and the organizing committee of this year’s Bunsen-Tagung are pleased to showcase contributions describing recent research in physical chemistry either to the main topic of energy transformations or to the general topics of Physical Chemistry.

This themed collection is Guest Edited by Timo Jacob (Ulm University), Swetlana Schauermann (Kiel University), Robert Schlögl (Fritz Haber Institute of the Max Planck Society), and Alec Wodtke (Georg-August University & Department of Dynamics at Surfaces, Max-Planck-Institute for Multidisciplinary Sciences).
