1. 1. Study of polycrystalline gold surfaces by potential-dependent optical sum frequency generation

   Författare :Sara Boscolo Bibi; Tony Hansson; Magnus Johnson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

   Sammanfattning : With the increase in demand for renewable energy, the comprehension of chemical processes is essential to improve the design of catalysts in order to achieve better performance. This thesis summarizes the experimental investigation of redox reactions on polycrystalline gold surfaces by combining electrochemistry with operando surface-specific sum frequency generation (SFG) for a wider anodic potential interval than previously studied in acidic aqueous medium (H3PO4, pH 1).

3. 2. Going for gold : A spectroelectrochemical and catalytic study of gold materials

   Författare :Sara Boscolo Bibi; Hansson Tony; Sergey Koroidov; Henrik Öström; Richard Kramer Campen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gold oxidation; oxide-derived metals; electrochemistry; X-ray spectroscopy; optical nonlinear spectroscopy; AuNPs supported in metal oxides; mass spectrometry; kemisk fysik; Chemical Physics;

   Sammanfattning : With the increase in demand for renewable energy, understanding chemical processes is essential for improving the design of catalysts in order to achieve better performance. This thesis summarises the experimental investigation of three types of catalytic gold materials: gold oxide formed from gold films, oxide-derived gold (OD-Au) produced from gold films, and gold nanoparticles supported on metal oxides.
