Nanostructured electrocatalysts catalyst properties

Ex-situ methods such as diffraction methods show details about the electronic properties of nanostructures [104]. Catalysts made of electronically conducting Ru02 are surrounded by hydrous proton-conducting regions [105], which is necessary for the high activity of this material as a co-catalyst for CO-tolerant Pt-RuO c fuel cell electrocatalysts.

Simultaneously, Kim and co-workers [3] also explored the electrochemical catalytic properties based on electrospun Pt and PtRh nanowires for dehydrogenative oxidation of cyclohexane to benzene. In contrast to the conventional Pt nanoparticle catalysts (e.g., carbon/Pt or Pt black), Pt and PtRh electrospun nanowires electrocatalysts exhibited higher catalytic activities with the same metal loading amount. Furthermore, PtRh nanowires performed the best catalytic activities with a maximum power density of ca. 23 mWcm . Such higher electrocatalytic performances than Pt nanoparticles are attributed to the inherent physicochemical and electrical properties of ID nanostructures (Figure 4.1).
