Summary:

Studies of metal oxide catalysts have widely increased in recent years due to the important role that these materials play in industrial catalytic processes for the conversion of hydrocarbons, the control of environmental pollution and the synthesis of fuels. One of the most technologically relevant systems is Au/TiO2. However, further improvement of the properties of this supported catalyst is hampered by the lack of the fundamental atomic-scale knowledge on its design and performance. In relation to this, the aim of the present work was to prepare and investigate the model Au/TiO2 system and find out the chemistry of catalytic transformation of molecules.
