Covalent organic frameworks（COFs） are promising materials for mitigating polysulfide shuttling in lithium-sulfur（Li-S） batteries,but enhancing their ability to convert polysulfides across a wide temperature range remains a challenge,Herein,we introduce a redox-active COF（RaCOF） that functions as both a physical barrier and a kinetic enhancer to improve the temperature adaptability of Li-S batteries,The RaCOF constructed from redox-active anthraquinone units accelerates polysulfide conversion kinetics through reversible C=O/C-OLi transformations within a voltage range of 1,7 to 2.8 V（***+/Li）,optimizing sulfur redox reactions in ether-based *** conventional COFs,RaCOF provides bidentate trapping of polysulfides,increasing binding energy and facilitating more effective polysulfide ***-situ XRD and ToF-SIMS analyses confirm that RaCOF enhances polysulfide adsorption and promotes the transformation of lithium sulfide（Li2S）,leading to better sulfur cathode ***,RaCOF-modified Li-S batteries demonstrate low self-discharge（4.0% decay over a 7-day rest）,excellent wide-temperature performance（stable from-10 to+60℃）,and high-rate cycling stability（94% capacity retention over 500 cycles at 5.0 C）.This work offers valuable insights for designing COF structures aimed at achieving temperature-adaptive performance in rechargeable batteries.

Reducing the cost of RuO_(2)/TiO_(2)catalysts is still one of the urgent challenges in catalytic HCl *** the present work,a Ce-doped TiO_(2)supported RuO_(2)catalyst with a low Ru loading was developed,showing a high activity in the catalytic oxidation of HCl to Cl_(2).The results on some extensive characterizations of both Ce-doped TiO_(2)carriers and their supported RuO_(2)catalysts show that the doping of Ce into TiO_(2)can effectively change the lattice parameters of TiO_(2)to improve the dispersion of the active RuO_(2)species on the carrier,which facilitates the production of surface Ru species to expose more active sites for boosting the catalytic performance even under some harsh reaction *** work provides some scientific basis and technical support for chlorine recycling.
