The present study tries to give an insight to the combination of the homogeneous and heterogeneous catalytic properties in a new class of materials. Well dispersed gold nanoparticles on an ionic liquid layer supported on a mineral carrier have been prepared. This work is concentrated on the characterizations and understanding of the interactions between all the components of the catalytic syste...

Multidimensional shearforce-based constant-distance mode scanning electrochemical microscopy (4D SF/CD-SECM) was utilized for the investigation of the activity distribution of oxygen reduction catalysts. Carbon-supported Pt model catalyst powders have been immobilized in recessed microelectrodes and compared to a spot preparation technique. Microcavities serve as platform for the binder-free ca...

A novel MCM-41-supported base catalyst, Ba-MCM-41, was synthesized with a modified impregnation method. Ba2SiO4 was synthesized on the MCM-41 pore wall as confirmed by characterization using X-ray diffraction, X-ray photoelectron spectroscopy, X-ray fluorescence, N2 adsorption, Si MAS NMR and transmission electron microscopy. It was also demonstrated that a highly ordered Ba-MCM-41 catalyst wit...
