Novel Photocatalytic Applications of Sub-nanometer Gold Particles for Environmental Liquid and Gas Phase Reactions
Ultra small sub-1 nm gold nanoparticles were synthesized, characterized and deposited on TiO{sub 2} support. They exhibited a remarkable photocatalytic activity for both liquid and gas phase oxidation reactions, which have a significant potential for environmental applications. The NO{sub 2} conversion on such catalysts was 6 times higher as compared to that of unmodified catalysts. This is the first ever application of such small clusters for environmental photocatalysis. The presence of sub-1 nm clusters was confirmed by TEM, MALDI-TOF MS and UV-vis spectroscopy. This work also included the novel use of modified DRIFT spectroscopy for photocatalytic testing as well improvement of known Au clusters synthesis procedures.
