“Where Transient Catalysis meets the World of Instability”

Dear visitors and friends,

It is a pleasure to welcome you to our lab website, the home of the Heterogeneous Catalysis Laboratory (HCL) within the Chemistry Department at the University of Cyprus. Established in 1997 by Prof. A.M. Efstathiou, our laboratory pioneered the formation of the first research group and developed the country’s (island of Cyprus) first scientists with a Ph.D. in catalytic chemistry.

Throughout our journey, a primary focus of our research has been the utilization of advanced operando methodologies, such as DRIFTS-MS and UV-vis – Ms. Additionally, we employ a diverse array of well-designed step-gas switching experiments (Transient Method), including the use of stable isotopes (e.g., 13CO2, 13CO, 15NO, 18O2, D2, 13CH4) via SSITKA. These experiments, combined with other variations of step-gas switching, aim to provide in-depth fundamental information, such as intrinsic kinetic parameters (k’s, θ’s) and the chemical nature of active species, over the catalytic surface during real reaction conditions. Our emphasis lies in establishing robust relationships between this kinetic information and catalyst performance parameters (e.g., activity, selectivity, and stability with Time on Stream).

Our research spans various catalytic materials, including metal oxides and supported metal catalysts, applied to diverse catalytic reactions such as 16O/18O isotopic exchange, WGS, DRM, Fischer-Tropsch Synthesis, H2-SCR, NH3-SCR, CO2 hydrogenation, and Three-Way Catalysis.

Through the application of the aforementioned techniques, we have published over 170 papers in high-impact factor journals in the field of Catalysis (Physical Chemistry) and Chemical Engineering, accumulating over 7500 citations on Scopus and 9000 citations on Google Scholar.

In conclusion, I extend my warmest welcome to our Laboratory website and invite you to embark on an enjoyable journey into the realm of transient kinetics experimentation!

Greetings,
