Bimetal zeolite imidazolate framework derived Mo0.84Ni0.16-Mo2C@NC nanosphere for overall water splitting in alkaline solution

First-row transition metal-based materials derived from bimetallic metal–organic frameworks as highly efficient electrocatalysts for electrochemical water splitting

“…The high active site density and porous structure result in high overall water splitting performance of this electrocatalyst which showed an overpotential of 1.51 mV for overall water splitting. 258 Kim et al used NiMo-MOF as a precursor and synthesized Ni 3 S 2 /MoS 2 that was used in a water electrolyzer. 259 Hollow NiFe 2 O 4 @N/rGO-800 is also an efficient HER and OER electrocatalyst that has been used as a cathode and an anode in a water electrolyzer.…”

Highiy Efficient Water Splitting with Polyoxometalate Coated on Deliberately Designed Porous Carbon as a Bifunctional Electrocatalyst

“…ZIF8 with Zn as the central atom can be used to adjust the spatial distance of metal sites and generate more defects, because Zn atoms are easily evaporated at high temperatures (above 800 °C). In the precursor solution of MOFs, mixing different metal atoms can adjust the coordination of organics and metal ion clusters to obtain a core‐shell structure, which can lead to better electrocatalysts [18] . Based on our previous studies and considering that cobalt is one of the suitable transition metals for electrocatalytic reactions, we chose cobalt as the second metal to prepare ZnCo‐ZIF.…”

“…But their application has been impeded by the high price, monofunctional and poor stability. [15][16][17][18] Hence, we need to develop efficiency and cheap non noble metal-based bifunctional catalysts to meet its commercial application.…”

[18] Based on our previous studies and considering that cobalt is one of the suitable transition metals for electrocatalytic reactions, we chose cobalt as the second metal to prepare ZnCo-ZIF. In addition, Keggin-type POM-based catalysts have not received enough attention due to their insufficient active sites, so there are relatively few studies on the combination of MOF-derived materials and POM at present.…”

“…According to current research, standard catalysts for OER and HER correspond to Ru/Ir‐based oxides and Pt/C. But their application has been impeded by the high price, monofunctional and poor stability [15–18] . Hence, we need to develop efficiency and cheap non noble metal‐based bifunctional catalysts to meet its commercial application.…”
