Figure 3: Electrocatalytic properties of NiFe-MOF and other samples for OER.
From: Ultrathin metal-organic framework array for efficient electrocatalytic water splitting
(a) LSV plots obtained with NiFe-MOF, nickel-based metal-organic framework (Ni-MOF), bulk NiFe-MOF and IrO2 for OER at 10 mV s−1 in 0.1 M KOH. (b) Tafel plots obtained with NiFe-MOF, Ni MOF and bulk NiFe-MOF. (c) Rotate ring disk electrode voltammogram obtained for NiFe-MOF in 0.1 M KOH. The ring potential is set at 1.4 V versus reversible hydrogen electrode (RHE) to monitor the production of hydrogen peroxide; the inset of (c) shows the corresponding electron transfer number (N) as a function of applied potentials. (d) Chronoamperometric testing of NiFe-MOF for 20,000 s at 1.42 V (versus RHE) in 0.1 M KOH.
