Carbon cloth(CC)-based electrodes have attracted extensive attention for next-generation wearable energy-storage devices due to their excellent electrical conductivity and mechanical flexibility.However,the application of conventional CC-based electrodes for zinc(Zn)storage severely hinders Zn ion transport and induces deleterious Zn dendrite growth,resulting in poor electrochemical reliability.Herein,a novel oxygen plasma-treated carbon cloth(OPCC)is rationally designed as a current collector for flexible hybrid Zn ion supercapacitors(ZISs).The modified interface of OPCC with abundant oxygenated groups enables enhanced electrolyte wettability and uniform superficial electric field distribution.A prolonged working lifespan for Zn electrodeposition is achieved by the OPCC due to the improved interfacial kinetics and homogenized ion gradient.The as-prepared hybrid ZIS also delivers excellent cycling endurance(98.5%capacity retention for 1500 cycles)with outstanding operation stability under various extreme conditions.This facile surface modification strategy provides a new way for developing future flexible electrodes for wearable electronic products.

Enormous demands on the separation of oil/water(O/W)emulsions in various industries,such as petrochemical,food and pharmaceutical industries,are looking for high performance and energy-efficient separation methods.Ceramic membranes have been used to deal with O/W emulsions,for its outstanding characteristics of easy-operation,high-flux,and long-term stability.However,membrane fouling is still a challenge in the industrial application of ceramic membranes.Herein,antifouling ceramic membranes were fabricated by grafting zwitterions on the membrane surface via an environment-friendly two-step grafting method,which improves the antifouling property and permeability.Successful grafting of such zwitterion on the ceramic surface was assessed by the combination of FTIR and XPS characterization.More importantly,the hydration can be formed by electrostatic interactions layer on the modified membrane,which was confirmed by TGA characterization.The antifouling performance of prepared zwitterionic ceramic membranes in the separation of O/W emulsions was systematically tested.The results suggested that zwitterion can significantly improve the flux of ceramic ultrafiltration membrane,and can also improve antifouling property dramatically by reducing the irreversible fouling in the separation of O/W emulsions.Therefore,zwitterionic ceramic membranes hold promising potentials as an antifouling,highly efficient and green method in the practical purification of the O/W emulsions.

Hydrophilic ceramic membranes would be potential candidates for membrane gas absorption if they could be applied to appropriate separation processes.This study highlights a novel concept for the practical implementation of SO_2 absorption in hydrophilic ceramic membrane that exhibits outstanding thermal and mechanical stabilities.With this aim,we investigated experimentally the performance of SO_2 absorption into aqueous sodium hydroxide (NaOH) solution in a hydrophilic alumina (Al_2O_3) membrane contactor in terms of SO_2 removal efficiency and SO_2 mass transfer flux,and compared the performance with that in a hydrophobic one.A series of experiments were performed at various conditions over a NaOH concentration range of 0–1.0 mol·L^(-1),a liquid flow rate range of 30–180 ml·min^(-1),a gas flow rate range of 120–1000 ml·min^(-1),an inlet SO_2 concentration range of 400–2000μl·L^(-1),and a temperature range of 10–35°C.It was found that the hydrophilic membrane was more competitive when using a NaOH concentration higher than 0.2 mol·L^(-1).Furthermore,it can be inferred that the hydrophilicα-Al_2O_3 membrane exhibited exceptional long-term stability under 480 h continuous operation.

具有低表面能的疏水陶瓷膜常用于含水油液分离,而渗透通量的提高是提升膜分离过程经济性的关键.本文通过有机硅烷接枝改性制备疏水陶瓷膜,研究硅烷改性对不同孔径陶瓷膜结构及油水分离性能的影响。以孔径为1 000 nm、100 nm、10 nm的3种陶瓷膜为研究对象,考察不同孔径陶瓷膜硅烷化改性前后膜表面微观形貌、润湿性及渗透阻力的变化,评价3种孔径疏水陶瓷膜在溶剂、酸碱等环境下的稳定性,并将3种孔径硅烷改性的陶瓷膜用于油包水乳液分离.结果表明,孔径越小的膜硅烷化改性后渗透阻力增幅越大,尤其是当孔径达到10 nm,改性前后渗透阻力相差近3倍;原膜孔径对改性膜润湿性影响不大,且均表现出良好的耐溶剂性、耐酸碱性.低压高流速的操作方式有利于提高改性膜通量;对于水含量1 000μL/L的W/O乳液,3种改性膜对水的截留率均超过93%,渗透液水含量低于70μL/L,其中1 000 nm改性膜通量最高,达375 L/(m^(2)·h),而10 nm膜更不易被污染;对于水含量10%(体积分数)的W/O乳液,1 000 nm改性膜污染非常严重,通量迅速下降为14.1 L/(m^(2)·h),而100 nm改性膜污染程度较小,通量较高.

Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans(PCDD/Fs)have attracted widespread concern due to their high toxicity,and their difficult manipulation in laboratories has made the research process tough.Thus,in our work,furan is selected as the model compound owing to the same structure of a central oxygenate ring.Although catalytic oxidation is regarded as an effective and applicable method for the abatement of PCDD/Fs,the synthesis of low-temperature catalysts is still a challenging problem in practical applications.Considering this situation,we prepared a novel V_(2)O_(5)/TiO_(2)catalyst modified with N-doped hierarchical porous carbon(NHPC)via a wet impregnation method.The V/T-1%NHPC catalyst could achieve expectant low-temperature performances with 50%furan conversion at 150℃and a complete conversion at 200℃,which decreased 23℃and 40℃compared to the V/T catalyst respectively.Moreover,the addition of NHPC presented lifting chemical stability during long-time test.The addition of NHPC in V/T catalysts decreased the formation of crystalline V_(2)O_(5) and increased the percentages of V^(5+)and O_(lat),which improved the utilization of vanadium ions and the catalytic activity.Simultaneously,the higher binding energy shift of O_(lat) implied more reaction possibility with other oxidise reactants.Importantly,this work proved the lifting catalytic activity by the interaction between catalysts and NHPC,and proposed the promoting effects of the N element.The results showed that the content of the pyridinic N and graphitic N in NHPC changed after combining with V/T catalyst,which played crucial roles in the excellent catalytic performance.Overall,this work provides comprehensive research of the V/T-1%NHPC catalyst toward furan oxidation at low temperature and explain the effects of N-doped biomass carbon in catalytic activity clearly,which gave a new thought to design low-temperature catalysts in PCDD/Fs degradation.Besides,the internal functional mechanisms of N species are worth further exploratio
