Abstract Developing an efficient, green and low-cost non noble metal catalyst towards oxygen evolution reaction (OER) has been urgent for new generation of sustainable energy technologies. Herein, the Co/Ni metal-organic frameworks (MOFs) derived metal phosphides/ carbon matrix composites are successfully produced by the precipitation-carbonization-phosphorization processes. The obtained samples are characterized and analyzed for structural and morphological investigation. Electrochemical tests for OER are performed in alkaline medium. The positive effects of P, Ni doping in MOFs on the structure and properties of composites have been analyzed. Benefitting from the unique structure of three-dimensional flower-like polyhedron with rich structure and higher porosity, the NiCo-P/NC catalyst exhibits the lowest overpotential of 0.32 V compared with the commercial IrO2 (0.34V) at 10 mA cm−2, as well as outstanding stability and kinetic mechanism. Besides, the cost of the proposed novel material is calculated to be 4.337 US$/g, which is only 1.57 % of that of commercial IrO2 (276 US$/g). The results obtained from the MOF-derived low-cost and high-efficiency OER catalyst would provide a new perspective on application of electrochemical storage and batteries.

Abstract The post-synthetic installation of linker molecules between open-metal sites (OMSs) and undercoordinated metal-nodes in a metal-organic framework (MOF) — retrofitting — has recently been discovered as a powerful tool to manipulate macroscopic properties such as the mechanical robustness and the thermal expansion behavior. So far, the choice of cross linkers (CLs) that are used in retrofitting experiments is based on qualitative considerations. Here, we present a low-cost computational framework that provides experimentalists with a tool for evaluating various CLs for retrofitting a given MOF system with OMSs. After applying our approach to the prototypical system CL@Cu3BTC2 (BTC = 1,3,5-benzentricarboxylate) the methodology was expanded to NOTT-100 and NOTT-101 MOFs, identifying several promising CLs for future CL@NOTT-100 and CL@NOTT-101 retrofitting experiments. The developed model is easily adaptable to other MOFs with OMSs and is set-up to be used by experimentalists, providing a guideline for the synthesis of new retrofitted MOFs with modified physicochemical properties.
