Table 1 Comparison of Elemental Percentages in Ni-TEMPO-MOF Determined by XPS and EDS.
From: Structural functionalization of TEMPO modified Ni-MOF for electrocatalytic applications
Element | XPS Atomic Percentage (%) | EDS Atomic Percentage (%) | Comparative Explanation |
|---|---|---|---|
C | 46.73 | 34.25 | Higher carbon signal in XPS due to organic ligands and TEMPO modification layer |
N | 6.85 | 3.41 | Nitrogen proportion is higher in XPS, confirming the successful surface incorporation of TEMPO groups |
O | 25.12 | 28.67 | Oxygen content slightly higher in EDS, possibly due to oxide contributions from the copper foam substrate |
Ni | 21.3 | 33.67 | Lower Ni proportion in XPS due to limited probing depth compared to bulk-sensitive EDS |
