This doctoral thesis aims at demonstrating the technical feasibility of methane production from microalgae via continuous catalytic supercritical water gasification (CSCWG). This work focuses on three different research approaches: (i) assessment and impro ...
Metal organic supramolecular chemistry on surfaces has matured to a point where its underlying growth mechanisms are well understood and structures of defined coordination environments of metal atoms can be synthesized in a controlled and reproducible proc ...
We demonstrate that the combination of x-ray irradiation and capping by polyethylene glycol (PEG) produces excellent flexibility in controlling the structure of Au–Pd nanoparticles while preserving their catalytic performance. We specifically adopted two d ...

Catalyst design for selective hydrogenations is of major importance for the manufacturing of fine chemicals. Catalytic procedure which uses scarce and expensive noble metals is very challenging in terms of exclusive attack of a single functionality or subs ...
The catalytic properties of Pd have triggered a strong interest in the related catalysis by Au–Pd nanoparticles. However, the analysis of such phenomena has been complicated so far due to the presence of capping. Using X-ray irradiation, we produced uncapp ...
Catalytic system of Au nanoparticles supported on metal oxides has been developed to produce azoarenes in one-step directly from nitroarenes under mild conditions (30 °C, 1 bar of N2) using 2-propanol as solvent and reducing agent. Close to 100 % chemosele ...
Materials based on a combination of cerium-tungsten-titanium are potentially durable catalysts for selective catalytic NOx reduction using NH3 (NH3-SCR). Flame-spray synthesis is used here to produce WO3/CeOx-TiO2 nanoparticles, which are characterized wit ...
The effect of catalyst loading, composition, and calcination temperature on NH3 selective catalytic reduction (SCR) activity was investigated for metal vanadates of the type FexAl1-xVO4 (0
WO3/CeO2/TiO2, CeO2/TiO2 and WO3/TiO2 catalysts were prepared by wet impregnation. CeO2/TiO2 and WO3/TiO2 showed activity towards the selective catalytic reduction (SCR) of NOx by NH3, which was significantly improved by subsequent impregnation of CeO2/TiO ...
