Surface Intermediates in Photocatalysis or in Plasma Assisted Catalysis by Operando Infrared Spectroscopy


Fourier Transform InfraRed spectroscopy (FTIR) is extensively used for the characterization of catalytic materials and for understanding catalytic reactions. Commercial instruments now offer very interesting time resolution that can provide important tools for catalytic materials. A general overview will be given. Examples of new applications will be presented in two main domains: plasma assisted catalysis and photocatalysis.

In plasma assisted catalysis, operando IR evidenced the efficiency of plasma for decomposing organic species and for the preparation of heterogeneous catalysts. Nanoparticles of zeolites were prepared easily, with included reduced metal nanoparticles. Operando IR showed the reactions at work, and the role of the surface species. The role of water for generating active radicals was measured quantitativelin in kinetic studies. It also gave the first evidence for the role of the catalyst surface in isopropanol decomposition on alumina [6].

A new reactor was built for operando IR in photocatalysis. This reactor was used for studying methanol photooxidation [8]. The real reaction mechanism was determined and meaningful intermediates were distinguished from spectator species, in particular using isotope labelling in the SSITKA method.


to the European Conference on Materials and Technologies for Sustainable Growth website.

ECo MaTech will be held in Bled (Slovenia) from 19th to 21st of September 2013.

Eco MaTech is the third edition of a conference that started in 2009. The aim of ECo MaTech is to gather representatives of academic and R&D institutions, industry, governmental agencies and civil society to:

- present their work, ideas and products, 
- increase fruitful exhanges between all the actors involved in sustainable growth technologies, 
- increase the networking with sustainable growth professionals, 
- establish a general discussion platform on sustainable growth.


The conference excursion will take you to the Alpine lake Bohinj ( and waterfall Savica (
A farewell party will follow the lake trip by a boat. Comfortable shoes are recommended.

Only cash is exepted for on-site payment.

The poster panels are 1m wide and 2m high. The standrad A0 size posters are recommended (841mm:1189mm).
