3Three-Dimensional Cobalt Hydroxide Hollow Cube/Vertical Nanosheets with High Desalination Capacity and Long-Term Performance Stability in Capacitive Deionization显示文摘Faradaic electrode materials have significantly improved the performance of membrane capacitive deionization,which offers an opportunity to produce freshwater from seawater or brackish water in an energy-efficient way.However,Faradaic materials hold the drawbacks of slow desalination rate due to the intrinsic low ion diffusion kinetics and inferior stability arising from the volume expansion during ion intercalation,impeding the engineering application of capacitive deionization.Herein,a pseudocapacitive material with hollow architecture was prepared via template-etching method,namely,cuboid cobalt hydroxide,with fast desalination rate(3.3 mg(NaCl)·g^(-1)(h-Co(OH)2)·min^(-1)at 100 mA·g^(-1))and outstanding stability(90%capacity retention after 100 cycles).The hollow structure enables swift ion transport inside the material and keeps the electrode intact by alleviating the stress induced from volume expansion during the ion capture process,which is corroborated well by in situ electrochemical dilatometry and finite element simulation.Additionally,benefiting from the elimination of unreacted bulk material and vertical cobalt hydroxide nanosheets on the exterior surface,the synthesized material provides a high desalination capacity(117±6 mg(NaCl)·g^(-1)(h-Co(OH)2)at 30 mA·g^(-1)).This work provides a new strategy,constructing microscale hollow faradic configuration,to further boost the desalination performance of Faradaic materials.Yuecheng Xiong Fei Yu Stefanie Arnold Lei Wang Volker Presser Yifan Ren Jie Ma 2021Research2021,,1:1

5Corrigendum to“Three-Dimensional Cobalt Hydroxide Hollow Cube/Vertical Nanosheets with High Desalination Capacity and Long-Term Performance Stability in Capacitive Deionization”显示文摘In the article titled“Three-Dimensional Cobalt Hydroxide Hollow Cube/Vertical Nanosheets with High Desalination Capacity and Long-Term Performance Stability in Capacitive Deionization”[1],there was an error in the title.It previously read“Three-Dimensional Cobalt Hydroxide Hollow Cube/Vertical Nanosheets with High Desalinatio Capacity and Long-Term Performance Stability”,which was incorrect.The title in the original version has now been updated.Yuecheng Xiong Fei Yu Stefanie Arnold Lei Wang Volker Presser Yifan Ren Jie Ma 2021Research2021,,1:1

7Influence of structural depth of laser-patterned steel surfaces on the solid lubricity of carbon nanoparticle coatings显示文摘Carbon nanoparticle coatings on laser-patterned stainless-steel surfaces present a solid lubrication system where the pattern's recessions act as lubricant-retaining reservoirs.This study investigates the influence of the structural depth of line patterns coated with multi-walled carbon nanotubes(CNTs)and carbon onions(COs)on their respective potential to reduce friction and wear.Direct laser interference patterning(DLIP)with a pulse duration of 12 ps is used to create line patterns with three different structural depths at a periodicity of 3.5μm on AISI 304 steel platelets.Subsequently,electrophoretic deposition(EPD)is applied to form homogeneous carbon nanoparticle coatings on the patterned platelets.Tribological ball-on-disc experiments are conducted on the as-described surfaces with an alumina counter body at a load of 100 mN.The results show that the shallower the coated structure,the lower its coefficient of friction(COF),regardless of the particle type.Thereby,with a minimum of just below 0.20,CNTs reach lower COF values than COs over most of the testing period.The resulting wear tracks are characterized by scanning electron microscopy,transmission electron microscopy,and energy-dispersive X-ray spectroscopy.During friction testing,the CNTs remain in contact,and the immediate proximity,whereas the CO coating is largely removed.Regardless of structural depth,no oxidation occurs on CNT-coated surfaces,whereas minor oxidation is detected on CO-coated wear tracks.Timothy MACLUCAS Lukas DAUT Philipp GRÜTZMACHER Maria Agustina GUITAR Volker PRESSER Carsten GACHOT Sebastian SUAREZ Frank MÜCKLICH 2023Friction2023,11,7:0
8P2-type layered high-entropy oxides as sodium-ion cathode materials显示文摘P2-type layered oxides with the general Na-deficient composition Na_(x)TMO_(2)(x<1,TM:transition metal)are a promising class of cathode materials for sodium-ion batteries.The open Na+transport pathways present in the structure lead to low diffusion barriers and enable high charge/discharge rates.However,a phase transition from P2 to O2 structure occurring above 4.2 V and metal dissolution at low potentials upon discharge results in rapid capacity degradation.In this work,we demonstrate the positive effect of configurational entropy on the stability of the crystal structure during battery operation.Three different compositions of layered P2-type oxides were synthesized by solid-state chemistry,Na_(0.67)(Mn_(0.55)Ni_(0.21)Co_(0.24))O_(2),Na_(0.67)(Mn_(0.45)Ni_(0.18)Co_(0.24)Ti_(0.1)Mg_(0.03))O_(2) and Na_(0.67)(Mn_(0.45)Ni_(0.18)Co_(0.18)Ti_(0.1)Mg_(0.03)Al_(0.04)Fe_(0.02))O_(2) with low,medium and high configurational entropy,respectively.The high-entropy cathode material shows lower structural transformation and Mn dissolution upon cycling in a wide voltage range from 1.5 to 4.6 V.Advanced operando techniques and post-mortem analysis were used to probe the underlying reaction mechanism thoroughly.Overall,the high-entropy strategy is a promising route for improving the electrochemical performance of P2 layered oxide cathodes for advanced sodium-ion battery applications.Junbo Wang Sören L Dreyer Kai Wang Ziming Ding Thomas Diemant Guruprakash Karkera Yanjiao Ma Abhishek Sarkar Bei Zhou Mikhail V Gorbunov Ahmad Omar Daria Mikhailova Volker Presser Maximilian Fichtner Horst Hahn Torsten Brezesinski Ben Breitung Qingsong Wang 2022Materials Futures2022,1,3:0

10Selective Pb^(2+) removal and electrochemical regeneration of fresh and recycled FeOOH显示文摘Heavy metal pollution is a key environmental problem.Selectively extracting heavy metals could accomplish water purification and resource recycling simultaneously.Adsorption is a promising approach with a facile process,adaptability for the broad concentration of feed water,and high selectivity.However,the adsorption method faces challenges in synthesizing highperformance sorbents and regenerating adsorbents effectively.FeOOH is an environmentally friendly sorbent with low-cost production on a large scale.Nevertheless,the selectivity behavior and regeneration of FeOOH are seldom studied.Therefore,we investigated the selectivity of FeOOH in a mixed solution of Co^(2+),Ni^(2+),and Pb^(2+)and proposed to enhance the capacity of FeOOH and regenerate it by using external charges.Without charge,the FeOOH electrode shows a Pb^(2+)uptake capacity of 20 mg/g.After applying a voltage of-0.2/+0.8 V,the uptake capacity increases to a maximum of 42 mg/g and the desorption ratio is 70%-80%.In 35 cycles,FeOOH shows a superior selectivity towards Pb^(2+)compared with Co^(2+)and Ni^(2+),with a purity of 97%±3%in the extracts.The high selectivity is attributed to the lower activation energy for Pb^(2+)sorption.The capacity retentions at the 5^(th)and the 35^(th)cycles are ca.80%and ca.50%,respectively,comparable to the chemical regeneration method.With industrially exhausted granular ferric hydroxide as the electrode material,the system exhibits a Pb^(2+)uptake capacity of 37.4 mg/g with high selectivity.Our work demonstrates the feasibility of regenerating FeOOH by charge and provides a new approach for recycling and upcycling FeOOH sorbent.Lei Wang Lexane Deligniere Samantha Husmann Regina Leiner Carsten Bahr Shengjie Zhang Chaochao Dun Matthew M.Montemore Markus Gallei Jeffrey J.Urban Choonsoo Kim Volker Presser 2023Nano Research2023,16,7:0
