Transition Metal Compounds on Functionalized Multiwall Carbon Nanotubes for the Efficient Oxygen Evolution Reaction

“…Notably, the C 1s spectrum of 0.5Fe@MWCNT showed intense deconvoluted peaks at 286.4 and 288.2 eV, attributed to oxygen-rich functional groups such as C–O and O–CO (Figure e), respectively . According to recently published experimental and theoretical studies, the pulsed laser process generates oxygen-containing functional groups by solvent decomposition, increasing their concentration near the sample surface. , Hence, the PLA process functionalized the surface of the MWCNT supports, generating numerous thermodynamically favorable nucleation sites for the growth of Fe 2 O 3 nanoparticles. Notably, the O1s XPS spectrum of 0.5Fe@MWCNT exhibited a deconvoluted peak near 531.2 eV, corresponding to C–O–Fe bonds (Figure f), while the peaks observed for Fe 2 O 3 @MWCNT and Fe 2 O 3 indicated only Fe–O linkages (i.e., Fe–O and Fe–OH) .…”
