Catalysis using gold nanoparticles (AuNPs) is a topic of great interest due to their various beneficial properties towards different catalytic reactions of both academic and industrial importance. In this thesis, the preparation, characterization and application of a variety of AuNPs were studied. Our samples were investigated by different characterization methods such as UV-Vis, DLS, ICP-OES, XRF, TGA, BET, XRD, XPS, solid-state NMR, SEM, TEM etc. The catalytic properties of the samples were examined for three different reactions in both liquid and gas phase conditions.
