Abstract

Many photocatalysts work better or exclusively when a suitable cocatalyst, such as RuO2, is deposited on their surface. An innovative method of RuO2 deposition has been found to improve the performance of photocatalysts such as (Ga1-xZnx)(N1-xOx), WO3, SrTiO3 and TiO2. Here we use high angle annular dark field (HAADF) imaging, energy-dispersive X-ray (EDX) spectroscopy, and electron energy loss spectroscopy (EELS) in the scanning transmission electron microscope (STEM) to study the deposition of RuO2 on TiO2. The deposition process occurs in two steps, for each of which we are able to characterize the RuO2 distribution, morphology and crystallinity.
