LAFEC’s main research interests are focused in the fields of Heterogeneous Catalysis, and especially, in materials synthesis and characterization, catalyst development and evaluation, and investigation of reaction kinetics and mechanisms. Of particular interest is the investigation of the surface chemistry and structure of dispersed metallic systems and of reducible metal oxides and their mixtures. Materials are characterized using a combination of physicochemical techniques, including selective chemisorption of probe molecules, temperature programmed desorption, reduction and oxidation (TPR, TPO and TPD), FT-IR, Raman, XPS and XRD. In parallel to catalyst development and testing, fundamental studies are made to identify the surface parameters, which determine the catalytic performance. Identification of reaction pathways and mechanisms is accomplished with the combined use of in situ FT-IR spectroscopy and transient mass spectrometry, including steady-state isotopic transient kinetic analysis (SSITKA).
- Primary goals in the field of Heterogeneous Catalysis are:
- Production of hydrogen by reformation of biomass-derived components and derivatives.
- Development of catalytic materials for the selective methanation of CO2 in reformate gas
- Development of catalytic materials for the selective hydrogenation of CO2 for the production of higher alcohols
- Oxidation of volatile organic compounds (VOC) over metal and metal oxide catalysts.
- Development of novel catalysts for the selective reduction of NOx present in the exhaust of lean-burn and diesel engines.

BRIEF SUMMARY OF RESEARCH ACHIEVEMENTS
- Advanced catalyst synthesis:
Catalyst synthesis is a topic that is often overlooked in the heterogeneous catalysis academic circles, where simpler catalyst formulations with inferior performance are often used. However, the use of more sophisticated synthetic procedure can greatly improve the desirable catalyst properties (surface chemistry, metal dispersion etc.), boosting the catalytic performance. Our team has applied novel synthesis methods, including Pechini sol-gel, microwave sol-gel and hydrothermal synthesis using batch reactors to prepare novel catalysts with superior catalytic activity, in collaboration with Khalifa University (KU, Prof. K. Polychronopoulou) and the University of Hamburg (UHH, Prof. S. Mascotto). In short, microwave irradiation was found to improve metal dispersion and catalyst homogeneity, Pechini sol‑gel to tune the pore structure and volume, while hydrothermal synthesis to yield desirable metal‑oxide nanostructures (e.g., nanorods, nanocubes). Moreover, the nanoparticle exsolution approach has been applied to create intermetallic Fe-Ni nanoparticles supported on a perovskite support with superior stability.
- Advanced catalyst characterization and in‑situ characterization:
Thorough catalyst characterization is very important, as it provides a way to examine the physicochemical and surface properties of the catalyst, establish structure‑function relationships for the respective reactions (i.e., which catalyst properties prove beneficial) and examine catalyst deactivation following long-term experiments. This provides a way to tune the catalyst synthesis, so that the catalyst has these desired properties, tailored for the reaction at hand. Moreover, in‑situ characterization offers the possibility to observe the reaction intermediate surface species and shed light to the reaction mechanism. However, many of these sophisticated characterization techniques require very expensive equipment and large facilities, which are mostly unavailable to Greek institutions. Through the deep collaboration with the aforementioned institutions KU and UHH, along with the Technical University of Delft (TUD, Prof. A. Bansode), Prof. Goula’s team will be granted access to such facilities and equipment (e.g., beamtime in synchrotron facilities and high-pressure in-situ DRIFTS equipment), in order to perform thorough catalyst characterization.
- CO2 hydrogenation reactions:
CO2 utilization is a core EU green new deal challenge. Our has demonstrated expertise working on CO2 hydrogenation for CH4 production. The most significant findings were that modification of the CeO2-based supports in Ni/CeO2 catalysts with aliovalent dopants, and in particular Praseodymium, can improve the defect chemistry and oxygen lability of the support and even the metal dispersion. Moreover, the synthesis method was also deemed very important, as the generation of high porosity was necessary for the formation of Ni nanoparticles of the desired size. The CO2 methanation mechanism was also investigated via in-situ DRIFTS, in collaboration with TUD and it was found to follow the formate route. Lastly, the team also has expertise on the integrated CO2 capture and hydrogenation process via dual-function materials (DFMs).
- High-pressure reactions:
Expertise in the handling of high‑pressure reactor systems, since CO2 hydrogenation to higher alcohols and hydrocarbons requires high pressure to operate. Our team has demonstrated such expertise in relevant reactions including the hydrogenation of waste oils for green diesel production and the hydrocracking of heptane. Relevant equipment for gas and liquid product analysis (GC and GC-MS) are also used for the reaction at hand.
