Degradation study of arsenic oxides under XPS measurements

Terephthalate and trimesate metal–organic frameworks of Mn, Co, and Ni: exploring photostability by spectroscopy

“…We have used GL(30). 50 Curve tting parameters from high-resolution XPS spectra (HRXPS) are listed in Tables S1-S6. † The HRXPS Mn 2p spectrum of MnBDC had two peaks at $644 and $656 eV for Mn 2p 3/2 and Mn 2p 1/2 , respectively (Fig.…”

A dual colorimetric probe for rapid environmental monitoring of Hg2+ and As3+ using gold nanoparticles functionalized with d-penicillamine

“…The high-resolution As3d signal of the As 3+ -DPL-AuNPs at 44.5 eV was attributed to As 3+ -O bonds, while the As3d signal at 43.5 eV was ascribed to the binding energy of an As 3+ -N bond. [37][38][39] The TOF-SIMS spectra of the DPL-AuNPs, Hg 2+ -DPL-AuNPs, and As 3+ -DPL-AuNPs provide additional information regarding the sites of the binding of Hg 2+ and As 3+ to the DPL-AuNPs (Fig. 4).…”

Engineering 2D Arsenic‐Phosphorus Theranostic Nanosheets

“…After exposure to PBS for 14 days, an additional broad sub-band peak was observed in As 3d XPS spectrum, mainly attributing to the formation of AsO x , where the peaks centered at 43.84 and 45.44 eV could be assigned to As 2 O 3 and As 2 O 5 , respectively (Figure 3b 2 ). [26] As for P 2p region in AsP nanosheets, the peaks around 130.85 and 130.10 eV in fresh P 2p region were assigned to P 2p 1/2 and P 2p 1/3 , respectively, and a weak peak located at 135.10 eV could be ascribed to the formation of P x O y (Figure 3b 3 ). [27] After dispersed in PBS for 14 days, the area percentage of P-O in P 2p region was obviously increased, resulting in the decline of the intensity of P 2p 1/2 and P 2p 1/3 (Figure 3b 4 ).…”
