Interface effect in MIL-53(Fe)/metal-phenolic network (Ni, Co, and Mn) nanoarchitectures for efficient oxygen evolution reaction

Tuning the d-band states of NiFe-MOFs by combining early and late transition metals for enhanced electrocatalytic oxygen evolution

“…1b) and NiFe-MOF (Fig. S1†), the peaks at 8.9°, 16.7° and 17.9° could be indexed to the (200), (112) and (400) planes of MIL-53, 30 respectively. In Fig.…”

Electrocatalytic Properties of Electrochemically‐Polymerized Metal‐Phenolic Networks

“…[10,11] In fact, MPNs have already been applied as electrocatalysts, including for carbon dioxide and nitrogen reduction as well as water splitting. [11] The majority of work in this area has focused on tannic acid (TA)-based MPNs, [11][12][13][14] often in combination with other catalytic materials such as metal organic frameworks (MOFs), [13] nickel-based foams or electrodes, [10,14] or photoanodes. [15] These complexities have limited our ability to systematically study structure-property relationships of MPNs in catalysis, which is critical for their optimization as heterogeneous electrocatalysts.…”

A hybrid of MIL-53(Fe) rhombus and conductive CoNi2S4 nanosheets as a synergistic electrocatalyst for the oxygen evolution reaction

“…Ye et al 30 pro-duced CoNi 2 S 4 nanoparticles on the carbon cloth (CC) surface by a two-step hydrothermal vulcanization method, while the CoNi 2 S 4 /CC electrode exhibited excellent hydrogen precipitation activity (overpotential of 84 mV at 10 mA cm −2 ) and oxygen precipitation activity (overpotential of 228 mV at 10 mA cm −2 ). Ji et al 31 obtained the heterostructured catalyst MIL@TA-Ni by assembling a metal (Ni 2+ ) phenolic network on the surface of MIL-53, which exhibited excellent OER catalytic activity with an overpotential of 282 mV in 1 M KOH when the current density reached 10 mA cm −2 . Wu et al 32 skillfully loaded MIL-53(Fe) on Ni 3 S 2 nanosheet arrays to obtain the novel composite catalyst Ni 3 S 2 /MIL-53(Fe), which exhibited good OER activity thanks to its high porosity and large surface area, corresponding to current densities of 10 and 100 mA cm −2 at overpotentials of 214 and 251 mV, respectively.…”
