| 1 | Preparation of Sandwich-like NiCo2O4/rGO/NiO Heterostructure on Nickel Foam for High-Performance Supercapacitor Electrodes显示文摘A kind of sandwich-like NiCo_2O_4/rGO/NiO heterostructure composite has been successfully anchored on nickel foam substrate via a three-step hydrothermal method with successive annealing treatment. The smart combination of NiCo_2O_4, reduced graphene oxide(rGO), and NiO nanostructure in the sandwich-like nano architecture shows a promising synergistic effect for supercapacitors with greatly enhanced electrochemical performance. For serving as supercapacitor electrode, the NiCo_2O_4/rGO/NiO heterostructure materials exhibit remarkable specific capacitance of 2644 mF cm^(-2)at current density of 1 mA cm^(-2),and excellent capacitance retentions of 97.5% after 3000 cycles. It is expected that the present heterostructure will be a promising electrode material for high-performance supercapacitors. | Delong Li Youning Gong Miaosheng Wang Chunxu Pan | 2017 | Nano-Micro Letters2017，9，2： | 8 |

| 3 | Preparation of three-dimensional graphene foam for high performance supercapacitors显示文摘Supercapacitor is a new type of energy-storage device, and has been attracted widely attentions. As a two dimensional(2D) nanomaterials, graphene is considered to be a promising material of supercapacitor because of its excellent properties involving high electrical conductivity and large surface area. In this paper, the largescale graphene is successfully fabricated via environmental-friendly electrochemical exfoliation of graphite, and then, the three dimensional(3D) graphene foam is prepared by using nickel foam as template and FeCl_3/HCl solution as etchant. Compared with the regular 2D graphene paper, the 3D graphene foam electrode shows better electrochemical performance, and exhibits the largest specific capacitance of approximately 128 F/g at the current density of 1 A/g in 6 M KOH electrolyte. It is expected that the 3D graphene foam will have a potential application in the supercapacitors. | YunjiePing Youning Gong Qiang Fu Chunxu Pan | 2017 | Progress in Natural Science:Materials International2017，27，2： | 3 |
| 4 | Influence of graphene microstructures on electrochemical performance for supercapacitors显示文摘The influence of variant graphenes on electrochemical performance for supercapacitors was studied comparatively and systematically by using SEM,FTIR and Raman spectroscopy,cyclic voltammetry(CV),galvanostatic charge/discharge and electrochemical impedance spectroscopy(EIS).The results revealed that:1) the nitrogen-doped graphene(N-G) electrode exhibited the highest specific capacitance at the same voltage scan rate;2) the specific capacitance of the N-G reached up to 243.5 F/g at 1 A/g,while regular graphite oxide(GO) was 43.5 F/g and reduced graphene oxide(rGO) was 67.9 F/g;3) N-G exhibited the best supercapacitance performance and the superior electrochemical properties,which made it an ideal electrode material for supercapacitors. | Youning Gong Delong Li Qiang Fu Chunxu Pan | 2015 | Progress in Natural Science:Materials International2015，25，5： | 1 |

| 6 | Boron quantum dots all-optical modulator based on efficient photothermal effect显示文摘All-optical devices without external electronic components have drawn extraordinary attentions in all-optical communication.In this work,boron quantum dots(BQDs)were synthesized by a facile liquid-phase exfoliation method.The as-prepared BQDs showed good structural homogeneity and crystallinity,broadband optical absorption as well as excellent photothermal properties.Femtosecond-resolved transient absorption further revealed the short carrier relaxation time of BQDs.Inspired by the outstanding photothermal properties and ultrafast carrier dynamic of BQDs,we fabricated BQDsbased all-optical modulator.The phase shift with a slope efficiency of 0.032π/m W and response time of 0.97 ms can be achieved.The modulator was used in laser resonance cavity to achieve all-optical actively Q-switched laser operation with control repetition rate.This prototypical BQDs-based all-optical modulator shows a great potential to be applied in all-optical information processing and communication. | Cong Wang Qianyuan Chen Hualong Chen Jun Liu Yufeng Song Jie Liu Delong Li Yanqi Ge Youning Gong Yupeng Zhang Han Zhang | 2021 | Opto-Electronic Advances2021，4，7： | 0 |
