FUNDAMENTALS

S

New frontiers for the in-situ and operando spectroscopic investigation of interfaces applied to catalysis and electrochemistry

This symposium will focus on the characterization of catalytically- and electrochemically- relevant interfaces by means of in situ and operando spectroscopies. Recent advances in the use of single and combined spectroscopic methods (photoemission, absorption, IR, Raman, etc,) will be presented and perspectives will be discussed.

Scope

Interfaces are of fundamental importance to understand the behavior of catalytic and electrochemical materials under reaction conditions. Spectroscopic methods are often used to investigate such materials because they allow qualitative and/or quantitative characterization under reactive environments without perturbing the reaction. Among them, synchrotron-based techniques, such as absorption, emission and photoemission spectroscopy, and “laboratory-based” techniques, such as Infrared and Raman spectroscopy, have been developed. By means of such techniques it is possible to obtain an in situ characterization of a material, that is, exposing it to a reactive environment under realistic working conditions while simultaneously acquiring information about the evolution of its physical-chemical and morphological properties. At the same time, operando measurements, carried out on materials undergoing a reaction while measuring the catalytic activity/selectivity and product pattern, are extremely useful to determine the structure-chemical composition-reactivity relationships. The main goal of this symposium is to merge the research communities investigating catalytic and electrochemical interfaces with different in situ/operando spectroscopic techniques to share and discuss recent results, methods and perspectives. The development of time- and space-resolved in situ/operando spectroscopic investigations will also be a paramount topic. The symposium will be a unique opportunity to foster the collaboration among groups having different expertise, to attract potential users developing materials whose novel properties need to be characterized, and to introduce recently developed experimental setups employing more than one spectroscopic method at the same time.

Papers focused on the investigation of catalytic and electrochemical interfaces by means of in situ and operando spectroscopic methods are invited and will be published in a special issue of “Catalysis Today”.

 
Hot topics to be covered by the symposium
  • In situ and operando spectroscopic investigation of reactive interfaces (XPS, XAS, XES, IR, Raman)
  • Time and space-resolved spectroscopic investigation of reactive interfaces under  realistic working conditions
  • Development of new in situ and operando spectroscopic methods
  • Development of new experimental setups employing more than one spectroscopic method for the in situ and operando investigation of reactive interfaces (both laboratory- and synchrotron-based).
