Carbon and Oxygen-Doped Phosphorus Nitride (COPN) for Continuous Selective and Stable H2O2 Production

“…The N 1s peak of the P 3 N 5 sample could be deconvoluted into three peaks (397.7 eV for P�N−P, 399.1 eV for (N)P 3 and 401.6 eV for N−H/N−C). 37,48,49 In comparation, the COPN-3 sample exhibited three similar peaks, namely P�N−P/C−N�C (398.2 eV), (N)P 3 /(N)C 3 (399.9 eV), and N−H/N−C (402.4 eV), 49 albeit a red shift (higher binding energy) was observed for the N element. Similarly, deconvolution analysis of the P 2p high-resolution spectrum of P 3 N 5 resulted in two peaks (133.6 eV for P−N Figure 3b shows that COPN-3 exhibited a distinct reduction peak at 0.52 V RHE in the basic electrolyte in the presence of O 2 .…”

“…The deconvolution spectrum of C 1s in COPN had four peaks at 284.8, 286.6, 288.1, and 290.0 eV, corresponding to graphite sp 2 carbon (CC), nitrogen-doped carbon (C–N/C–O), CO bonds, and π–π* bonds, respectively (Figure S8a). The deconvolution spectrum of O 1s in COPN- X and P 3 N 5 (Figure S8) implied three peaks: the oxygen doubly bonds to phosphorus at 530.4 eV (OP), the oxygen singly bond to phosphorus at 532.2 eV (O–P), and the O in C–OH/C–O–C at 531.2 eV. , The fine XPS spectrum analysis of N and P for COPN- X ( X = 1, 3, 5) and P 3 N 5 are shown in Figure d,e, respectively. The N 1s peak of the P 3 N 5 sample could be deconvoluted into three peaks (397.7 eV for PN–P, 399.1 eV for (N)­P 3 and 401.6 eV for N–H/N–C). ,, In comparation, the COPN-3 sample exhibited three similar peaks, namely PN–P/C–NC (398.2 eV), (N)­P 3 /(N)­C 3 (399.9 eV), and N–H/N–C (402.4 eV), albeit a red shift (higher binding energy) was observed for the N element.…”

Coherent Sub‐Nanometer Interface between Crystalline and Amorphous Materials Boosts Electrochemical Synthesis of Hydrogen Peroxide

“…The C 1s XPS spectrum (Figure S7b, Supporting Information) displayed four peaks at binding energies of 284.8, 286.1, 287.6, and 289.2 eV, corresponding to sp 2 carbon (CC), CN, CO, and CO bonds, respectively. [ 24 ] Subsequently, the O 1s peak was further investigated to reveal a deconvolution of the O 1s spectrum (Figure S7c, Supporting Information) that indicated a three peak situation comprised of oxygen doubly bound to phosphorus (OP) at 531.4 eV, oxygen singly bound to phosphorus (OP) at 533.2 eV, [ 25 ] and oxygen bound to carbon (OC) or adsorbed H 2 O (OH) at 535.6 eV, [ 26 ] respectively. The high‐resolution spectra of the N 1s peak (Figure 3c) of the P 3 N 5 /P 3 N 5 O X ‐X sample can be deconvoluted into three peaks corresponding to PNP (397.8 eV), PNP (399.3 eV), and NC (401.4 eV).…”
