WebOct 9, 2024 · One of the obstacles to long-term performance of fuel cells is the corrosion carbon support for the electrocatalysts. Titania (TiO 2), with its robust corrosion resistance, is already used as a catalyst support for a range of reactions.However, with a bandgap of around 3 - 3.4 eV depending on the type of polymorph, it is too insulating to serve as an … WebX-ray photoelectron spectra (XPS) of Nd-doped phosphate glasses were recorded before and after γ-irradiation using monochromatic Al K α line emission. X-ray was focused on the surface of the sample, and core level of the Nd 3d spectra was studied. Fig. 13.15 shows the XPS spectra of glass sample #1 before and after 10 and 500 kGy γ-irradiation.
