| 1 | Rationally exfoliating chitin into 2D hierarchical porous carbon nanosheets for high-rate energy storage显示文摘Two-dimensional(2D)carbon nanomaterials with hierarchical porous structure and heteroatoms doping are highly desirable in the fields of energy storage because of their rich active surface and open ion diffusion channels.However,the scalable preparation of carbon materials simultaneously possessing ultrathin 2D feature and hierarchical pores remains a considerable challenge.Herein,a facile one-step method to massively fabricate 2D porous chitin nanosheets(coded as PCNs)via a phytic acid assisted top-down exfoliation of bulk chitin under hydrothermal treatment was presented.Subsequently,2D carbon nanosheets with extra-thin thickness(3.6 nm),well-defined hierarchical porosity,high specific surface area(855 m2·g^-1),as well as abundant self-doped heteroatoms(N,O,P)were fabricated by carbonizing the PCNs,and was named as HPCNs.The as-obtained HPCNs demonstrated remarkable electrochemical performance as electrode material for supercapacitors.The symmetric supercapacitors(SSCs)based on HPCNs exhibited a high specific capacitance of 79 F·g^-1(316 F·g^-1 for single electrode)in 6 M KOH aqueous electrolyte solution,as well as a remarkable energy density of 23.8 W·h·kg^-1 by using 1 M Li2SO4 as electrolyte.It is also demonstrated that HPCNs/PCNs hybrid dispersions can be used as inks to fabricate conductive films and energy devices with high strength and superior flexibility.This work paves a new avenue for the economical and large-scale synthesis of 2D hierarchically porous carbon materials for energy storage related applications. | Lingfeng Gao Guoqun Zhang Jie Cai Liang Huang Jun Zhou Lina Zhang | 2020 | Nano Research2020，13，6： | 2 |

| 8 | Stable Metal–Halide Perovskite Colloids in Protic Ionic Liquid显示文摘Obtaining long-term stable and robust perovskite colloids solution remains an important scientific challenge due to the limited interaction between solvent and perovskite solutes.Here,we unveil the formation mechanism of chemically robust perovskite precursor solutions under ambient conditions using methylammonium acetate(CH3NH3•CH3COO,MAAc)protic ionic liquid(PIL)solvent.Tens of nanometers colloids are assembled on the molecular level via regular oriented gel-like lamellae with a mean thickness of 34.69 nm,width of 56.81 nm,and distance of 91.05 nm. | Hao Gu Tingting Niu Shouwei Zuo Yongqing Cai Lingfeng Chao Peter Müller-Buschbaum Yingdong Xia Jing Zhang Guichuan Xing Yonghua Chen | 2022 | CCS Chemistry2022，4，10： | 0 |
