TiO2/WO3/Au nanoarchitectures' photocatalytic activity “from degradation intermediates to catalysts' structural peculiarities” Part II: Aerogel based composites - fine details by spectroscopic means

- The intermediates' formation is dependent from the synthesis pathway.
- Bulk-structural aspects influenced the intermediates: crystallinity grade, doping.
- Surface-structural aspects governed the intermediates: W and Ti species.
- The gold's deposition wavelength had a major impact on the WO3 structure.
- The intermediates' formation can be manipulated by the ratio of different species.
