Abstract: Exploring effective electrocatalysts for oxygen evolution reaction (OER) is a crucial requirement of many energy storage and conversion systems, involving fuel cells, water splitting, and metal–air batteries. Herein, a heterogeneity metal‐organic framework (MOF) is prepared by the assembling of metals, terephthalic (A) and 2‐aminoterephthalic ligands (B), defined as A2.7B‐MOF‐FeCo1.6. More importantly, A2.7B‐MOF‐FeCo1.6 exhibits excellent OER activity with an ultralow overpotential of 288 mV at 10 mA cm−2 and a Tafel slope of 39 mV dec−1. The high electrocatalytic performance for OER is attributed to the optimized electronic structure of the intrinsic catalytic center in MOFs via the engineering of the metal node and linkers. The work offers not only a benchmark for pure MOFs in electrocatalysis but also a new efficient strategy to improve electrocatalytic performance by electronic structure engineering of catalytic active centers in MOFs.

Bimetallic Zeolitic Imidazolite Framework Derived Carbon Nanotubes Embedded with Co Nanoparticles for Efficient Bifunctional Oxygen Electrocatalyst
Abstract: Bifunctional oxygen catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) with high activities and low‐cost are of prime importance and challenging in the development of fuel cells and rechargeable metal–air batteries. This study reports a porous carbon nanomaterial loaded with cobalt nanoparticles (Co@NC‐x/y) derived from pyrolysis of a Co/Zn bimetallic zeolitic imidazolite framework, which exhibits incredibly high activity as bifunctional oxygen catalysts. For instance, the optimal catalyst of Co@NC‐3/1 has the interconnected framework structure between porous carbon and embedded carbon nanotubes, which shows the superb ORR activity with onset potential of ≈1.15 V and half‐wave potential of ≈0.93 V. Moreover, it presents high OER activity that can be further enhanced to over commercial RuO2 by P‐doped with overpotentials of 1.57 V versus reversible hydrogen electrode at 10 mA cm−2 and long‐term stability for 2000 circles and a Tafel slope of 85 mV dec−1. Significantly, the nanomaterial demonstrates better catalytic performance and durability than Pt/C for ORR and commercial RuO2 and IrO2 for OER. These findings suggest the importance of a synergistic effect of graphitic carbon, nanotubes, exposed Co–Nx active sites, and interconnected framework structure of various carbons for bifunctional oxygen electrocatalysts.

MOF-derived Mn doped porous CoP nanosheets as efficient and stable bifunctional electrocatalysts for water splitting
Yinle Li,Baoming Jia,Boyuan Chen,Qinglin Liu,Mengke Cai,Ziqian Xue,Ya-Nan Fan,Hai-Ping Wang,Cheng-Yong Su,Guangqin Li +9 more
TL;DR: The as-prepared porous Mn-CoP nanosheets had a larger specific surface area and higher porosity, furnishing them with more plentiful catalytically active sites than their counterpart hollow CoP and Mn- coP nanoparticles, and thus showed much better electrocatalytic activity for both HER and OER in acidic and alkaline media.
