Aug 20, 2020 · Iron phthalocyanine (FePc) is a promising non-precious catalyst for the oxygen reduction reaction (ORR). Unfortunately, FePc with plane-symmetric FeN 4 site usually exhibits an unsatisfactory...

Mar 13, 2023 · We find that the presence of oxygen functional groups on the carbon nanotube (CNT) surface generates electron-deficient cobalt phthalocyanine (CoPc) and that this optimally modulates the...

Oct 16, 2020 · A pair of broad redox peaks are observed in the CV curve of pure FePc, indicating the typical specific pseudocapacitive behavior with a capacitance of 45 F g −1 at scan rate of 100 mV s −1 (Fig. S7a).

Oct 1, 2022 · Spectroscopic investigations confirmed the existence of FePc moieties in the prepared poly-FePc catalyst. Poly-FePc displayed superior ORR performance in terms of activity, durability, and methanol tolarance. DFT calculations indicated the down-shift in eg-orbital energy of FePc to facilitate ORR.

Jul 2, 2020 · Among various MPc, iron phthalocyanine (FePc) gives best ORR performance, presumably because of its strong electron withdrawing capability. Herein, we report one pot solvothermal synthesis of 1 Dimensional FePc nanostructure and …

Carbon-supported Fe-14MR (Fe-14MR/C) and FePc (FePc/C) were prepared, and their structures and demetalation behavior were evaluated to compare the durability of the Fe active site in a 14-membered ring to that in a 16-membered ring.

Mar 14, 2020 · Iron (II) phthalocyanines (FePcs) are an attractive metal-source catalyst due to its unique properties such as centrosymmetric structure and electron-donating ability, thanks to their large conjugated molecular structure and strong interactions between aromatic rings [21, 22].

Jul 5, 2019 · Initially, the cyclic voltammetry (CV) measurements were performed to investigate the ORR activities of FePc, N-GP950, and FePc-33/N-GP950 catalysts in 0.1 M KOH solution. The CV curves, Fig. 4 a, displays distinguishing cathodic peaks of oxygen reduction in the O 2 -saturated electrolyte.

Aug 1, 2022 · The cyclic voltammetry (CV) curves of FePc-MoS 2, FePc*-MoS 2 and FePc-Py-MoS 2 exhibited apparent cathodic peaks in O 2-saturated 0.1 M KOH electrolyte (Figure S10), while no peaks can be observed under Ar-saturated …

Jan 12, 2024 · In this Article, we employ FTacV to probe the ORR kinetics using a model PGM-free catalyst, an iron phthalocyanine (FePc). The quantitative analysis of the electrocatalytic activity using FTacV...
