PALLADIUM CATALYSTS BASED ON POROUS AROMATIC FRAMEWORKS FOR VANILLIN HYDROGENATION: TUNING THE ACTIVITY AND SELECTIVITY BY INTRODUCING FUNCTIONAL GROUPS

The aim of the current work was to study the activity of supported palladium catalysts based on porous aromatic frameworks (PAF) in vanillin hydrogenation, and to develop the methods for controlling their activity and selectivity by modifying the PAF folk rivet sweat structure with various functional groups.Using unmodified PAF-30, its sulfonated d

Helicopter blades are currently constructed with composite materials enveloping honeycomb cores with only the leading and trailing edges made folk rivet sweat of metal alloys.In some cases, the erosive wear of the bound between the composite skin and metallic leading edge leads to full blade failure.It is therefore the goal of this paper to provide
