| 1 | Two-dimensional polymer nanosheets for efficient energy storage and conversion显示文摘As a promising graphene analogue,two-dimensional(2D)polymer nanosheets with unique 2D features,diversified topological structures and as well as tunable electronic properties,have received extensive attention in recent years.Here in this review,we summarized the recent research progress in the preparation methods of 2D polymer nanosheets,mainly including interfacial polymerization and solution polymerization.We also discussed the recent research advancements of 2D polymer nanosheets in the fields of energy storage and conversion applications,such as batteries,supercapacitors,electrocatalysis and photocatalysis.Finally,on the basis of their current development,we put forward the existing challenges and some personal perspectives. | Yumei Ren Chengbing Yu Zhonghui Chen Yuxi Xu | 2021 | Nano Research2021，14，6： | 3 |

| 4 | Highly crystalline vinylene-linked covalent organic frameworks enhanced solid polycarbonate electrolyte for dendrite-free solid lithium metal batteries显示文摘The development of solid-state electrolytes(SSEs)with high ionic conductivity,outstanding electrochemical window,and promising mechanical strength is a key factor in realizing the commercialization of high energy density solid-state lithium metal batteries(LMBs).Covalent organic frameworks(COFs)are a functional crystalline material with highly customizable molecular networks and one-dimensional channel structures,thus showing great potential applications in SSEs.Herein,we design flexible COF-poly(vinyl ethylene carbonate)(PVEC)(abbreviated as COF-PVEC)composite electrolyte films with excellent ionic conductivity and high mechanical strength,enabling dendrite-free and long-term running solid-state LMBs.Owing to the lithiumphilic triazine and carbon–carbon double bonds groups in the COF skeleton,the obtained flexible COF-PVEC shows high ionic conductivity up to 1.11×10^(−4)S·cm^(−1)at 40℃,and enlarged electrochemical window up to 4.6 V(vs.Li^(+)/Li)compared with pure PVEC electrolyte.At the same time,the lithium dendrites are efficiently inhibited after discharge–charging cycles,due to the improved Young’s modulus(150 MPa)and ordered channels of COF.Using the various features of COF-PVEC,we assembled a solid-state full battery with LiFePO4 cathode,which showed superior rate capacity(151.8,146.2,139.2,128.1,113.7,and 100.8 mAh·g^(−1)at 0.1,0.2,0.5,1,1.5,and 2 C,respectively)and excellent long-term cycling stability(over 400 cycles at 1 C).We believe that the COF-based composite electrolyte can become one of the most promising high-performance SSEs for solid-state LMBs. | Kaige Zhang Chaoqun Niu Chengbing Yu Li Zhang Yuxi Xu | 2022 | Nano Research2022，15，9： | 0 |
| 5 | Monomer-dependent synthesis of secondary amine-linked triazine-based two-dimensional polymers nanosheets显示文摘Expanding the structural diversity of crystalline two-dimensional polymers(2DPs) is highly desired but remains a considerable challenge. Herein we report the first synthesis of novel crystalline secondary amine-linked triazine-based 2DPs(SAT-2DPs) by using benzidine or 4, 4′′-diamino-p-terphenyl and cyanuric chloride under solvothermal conditions. We find the structures of diamine-based monomers play a crucial role in deciding whether the synthesized material is crystalline 2DPs nanosheets or amorphous nanoparticles, which is unexpected and provides an important understanding of the 2D polymerization mechanism.The obtained SAT-2DPs not only show a lateral size of micrometers and an ultrathin thickness of a few nanometers, but also demonstrate high crystallinity with a unique ABC stacking configuration, excellent solvent dispersibility and superior thermal stability. In addition, the resultant SAT-2DPs are used to guide uniform lithium-ion deposition due to their abundant nitrogen atoms and ordered open channels. The assembled asymmetric coin cells(Li|Cu) with SAT-2DPs realize the average coulombic efficient up to 99.3% during discharge-charge cycles. This work provides valuable insights into the synthesis of new 2DPs for various applications. | Ranran Zhao Chaoqun Niu Mohamed FAly Aboud Imran Shakir Chengbing Yu Yuxi Xu | 2020 | Science China Chemistry2020，63，7： | 0 |
| 6 | Step-edge controlled fast growth of wafer-scale MoSe_(2)films by MOCVD显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDCs),due to their unique physical properties,have a wide range of applications in the next generation of electronics,optoelectronics,and valleytronics.Large-scale preparation of high-quality TMDCs films is critical to realize these potential applications.Here we report a study on metal-organic chemical vapor deposition(MOCVD)growth of wafer-scale MoSe_(2)films guided by the crystalline step edges of miscut sapphire wafers.We established that the nucleation density and growth rate of MoSe_(2)films were positively correlated with the step-edge density and negatively with the growth temperature.At a certain temperature,the MoSe_(2)domains on the substrate with high step-edge density grow faster than that with low density.As a result,wafer-scale and continuous MoSe_(2)films can be formed in a short duration(30 min).The MoSe_(2)films are of high crystalline quality,as confirmed by systematic Raman and photoluminescence(PL)measurements.The results provide an important methodology for the rapid growth of wafer-scale TMDCs,which may promote the application of 2D semiconductors. | Rui Ji Jing Liao Lintao Li Rongji Wen Mengjie Liu Yifeng Ren Jianghua Wu Yunrui Song Minru Qi Zhixing Qiao Liwei Liu Chengbing Qin Yu Deng Yongtao Tian Suotang Jia Yufeng Hao | 2023 | Nano Research2023，16，7： | 0 |
