在Mn-NaHCO3上获得了更高的化学反应速率(rs),更快的归一化反应速率(rnorm)和更低的表观活化能以及更大的表面锰元素周转频率(TOFMn),这些均佐证了Mn-NaHCO3具有更高的催化活性。 Figure. 3XPS spectra of (a) Mn 2p, (b) Mn 3s, (c) O 1s and (d) C 1s of Mn-NaHCO3, Mn-KHCO3 and MnCO3 ...
Calculated Mn(2p 3/2 ) X-ray photoelectron spectra (XPS) of Mn 2+ , Mn 3+ , and Mn 4+ free ions are strikingly similar to Mn(2p 3/2 ) spectra of Mn 2+ -, Mn 3+ -, and Mn 4+ -oxides and oxyhydroxides, indicating that these ions adopt high spin states in M
