Hydrothermal self-assembly of α-Fe2O3 nanorings@graphene aerogel composites for enhanced Li storage performance

Comparison between Fe2O3/C and Fe3C/Fe2O3/Fe/C Electrocatalysts for N2 Reduction in an Alkaline Electrolyte

“…The experimental XPS spectra were deconvoluted using the Gaussian–Lorentzian peak after background subtraction in the baseline mode. As shown in Figure S4a,b, there were three O 1s peaks at 530.5, 531.8, and 533.5 eV, indicating Fe–O, C–O–Fe, and C–OH/C–O–C bonds, respectively . In the O 1s spectrum, the intensity of the Fe–O bond in the Fe 3 C/Fe 2 O 3 /Fe/C catalyst was significantly lowered than that of the Fe 2 O 3 /C catalyst.…”

Enhancing the Photoelectrochemical Water Oxidation Activity of α‐Fe2O3 Thin Film Photoanode by Employing rGO as Electron Transfer Mediator and NiFe‐LDH as Cocatalyst

“…Another observed peaks located at 715.5 and 733.2 eV are ascribed to the satellite peaks of α‐Fe 2 O 3 . Figure 4b shows the O 1s spectrum in the composite, the two peaks at 529.4 and 534.9 eV attribute to Fe−O and C−OH/C−O−C bonds, respectively [32,38] . Besides, the distinct peak at 531.1 eV matches well with O−H bond due to the electrodeposition of NiFe‐LDH cocatalyst [34,39] .…”

SrTiO3@NiFe LDH core–shell composites for photocatalytic CO2 conversion

“…This result indicated that the relative amount of H-O bonds decreased, which was consistency of deduction from Ti 2p analysis. [48][49][50] In addition, X-band electron paramagnetic resonance spectroscopy (EPR) was also carried out to examine oxygen vacancies due to the existence of single electron in Ti 3+ . The results were shown in Fig.…”
