Perovskite materials are typically used as oxygen electrodes of solid oxide fuel and electrolysis cells (SOC). The high stability of the perovskite structure in oxidative environments makes it a good candidate as a cathode electrode for steam electro

For several decades an open question in many X-ray photoelectron spectroscopy (XPS) studies was whether or not the results obtained in ultra-high vacuum conditions (UHV) were representative of the sample state in gas atmospheres. As a consequence, ne

The role of surface chemistry of modified MWCNT on the development and characteristics of Pt supported catalysts

Autor: Fotios Paloukis, Maria K. Daletou, Eirini Zagoraiou

Publikováno v: Nano-Structures & Nano-Objects. 24:100566

The performance and stability of electrocatalysts strongly depend on the physicochemical characteristics, such as the surface area, the crystalline structure, size and shape of the particles and the interactions with the support. Platinum (Pt) is one
