Abstract Metal–organic frameworks and covalent organic have been widely employed in electrochemical catalysis owing to their designable skeletons, controllable porosities, well‐defined catalytic centers. However, the poor chemical stability low electron conductivity limited activity, single‐functional sites these hindered them show multifunctional roles systems. Herein, we constructed novel metal polymers (Co‐HAT‐CN Ni‐HAT‐CN) with dual centers (metal–N 4 metal–N 2 ) catalyze oxygen reduction reaction (ORR) evolution (OER). By using different centers, activity selectivity were well‐tuned. Among them, Co‐HAT‐CN catalyzed ORR a 4e − pathway, half‐wave potential of 0.8 V versus RHE, while Ni‐HAT‐CN 2e pathway H O over 90%. Moreover, delivered an overpotential 350 mV at 10 mA cm −2 corresponding Tafel slope 24 dec −1 for OER 1.0 M KOH aqueous solution. The experimental results revealed that activities toward due M–N frameworks, both contributed OER. This work gives us new platform construct bifunctional catalysts.

Lithium-sulfur (Li-S) batteries with high energy density are currently receiving enormous attention. However, their redox kinetics at low temperature is extremely tardy, and polysulfides shuttling serious temperature, which severely hinders the implementation of wide-temperature Li-S batteries. Herein, we propose an all-climate battery based on ether-based electrolyte by using a porous sub-nano aromatic framework (SAF) modified separator. It's demonstrated that fully conjugated SAF-3 small pore size (0.97 nm) narrow band gap (1.72 eV) could efficiently block elevated boost conversion temperature. Consequently, cells work well in wide ranging from -40 to 60 °C. Furthermore, when operated room cell exhibits 90 % capacity retention over 100 cycles under high-sulfur loading (5.0 mg cm-2 ) lean (5 μL mg-1 ).
