Origins of sp3C peaks in C1s X-ray Photoelectron Spectra …
WebThe XPS C1s peaks at 284.0 eV, 286.1 eV and 295.5 eV are associated with sp 2 and sp 3 -hybridized carbon (C C and C C), hydroxyl/phenols (C OH) and carboxyl (O C O) groups, respectively. WebC1s peak at 284.8 corresponding to Adventitious Carbon is a reference for the X-ray photoelectron spectroscopy (XPS. However, when using carbon-based support, say Vulcan carbon (rich in... WebXPS is a method for analyzing the surface of a material. It can provide useful information on the nature of the functional groups and the functionalization of GNO.
