A Facile and Template-Free One-Pot Synthesis of mn_3O_4 Nanostructures as Electrochemical Supercapacitors

引用

Nano-micro Letters 2016年第2期8卷 165-173页

作者： Zhenjun Qi Adnan younis Dewei Chu Sean Li School of materials Science and Engineering University of New South Wales

In this paper, we report an effective, simple, and cost-effective strategy of electrochemical deposition to prepare hausmannite mn_3O_4 thin films for the applications of supercapacitors. Various precursor concentrations and deposition durations were manipulated to tailor the surface morphologies of mn_3O_4 nanostructures and to optimize their electrochemical performances. The mn_3O_4 samples prepared at 0.05 m mn(NO3)2solution for 30 min delivered a large gravimetric specific capacitance of 210 F g-1at a current density of 0.5 A g-1, and a good rate capability over other samples. This superior electrochemical performance may be attributed to the improved electrode conductivity with increased accessible area for electrolytes ions. Furthermore, a nanocomposite film based on mn_3O_4/carbon foam was fabricated by utilizing the developed optimized conditions. The mn_3O_4/carbon foam films exhibit an excellent specific capacitance with negligible degradation in retaining specific capacitance values up to 4000 cycles. These findings could further broaden the applications of hausmannite mn_3O_4 in electrochemical energy storage electrodes.

Nanostructured Ternary metal Tungstate-Based Photocatalysts for Environmental Purification and Solar Water Splitting:A Review

引用

Nano-micro Letters 2018年第4期10卷 201-227页

作者： Jun Ke m.Adnan younis Yan Kong Hongru Zhou Jie Liu Lecheng Lei Yang Hou School of Chemistry and Environmental Engineering Wuhan Institute of Technology Key Laboratory of Biomass Chemical Engineering of ministry of Education College of Chemical and Biological Engineering Zhejiang University Department of Environmental Science and Engineering North China Electric Power University

Visible-light-responsive ternary metal tungstate(mWO_4) photocatalysts are being increasingly investigated for energy conversion and environmental purification applications owing to their striking features, including low cost,eco-friendliness, and high stability under acidic and oxidative conditions. However, rapid recombination of photoinduced electron–hole pairs and a narrow light response range to the solar spectrum lead to low photocatalytic activity of mWO_4-based materials, thus significantly hampering their wide usage in practice. To enable their widespread practical usage, significant efforts have been devoted, by developing new concepts and innovative strategies. In this review, we aim to provide an integrated overview of the fundamentals and recent progress of mWO_4-based photocatalysts. Furthermore, different strategies, including morphological control, surface modification, heteroatom doping, and heterojunction fabrication, which are employed to promote the photocatalyticactivities of mWO_4-based materials, are systematically summarized and discussed. Finally, existing challenges and a future perspective are also provided to shed light on the development of highly efficient mWO_4-based photocatalysts.

Physical properties of three short period close binaries:KIC 2715417,KIC 6050116 and KIC 6287172

引用

Research in Astronomy and Astrophysics 2019年第2期19卷 111-124页

作者： mahmoud AbdelFattah NegmEldin Ahmed Essam elsayed Shahinaz mostafa Yousef Astronomy Space Science and Meteorology Department Faculty of Science Cairo University Department of Astronomy National Research Institute of Astronomy and Geophysics(Egypt)

We present the physical parameters of three short period close binaries using data observed from the Kepler Space Telescope. All of these observations were taken in a single bandpass(which approximates the Johnson V-band). Our three systems are KIC 2715417, KIC 6050116 and KIC 6287172. The first system, KIC 2715417, is considered a semi-detached system with the secondary component filling its Roche lobe. The second system, KIC 6050116, is an overcontact system, while the third system, KIC 6287172, belongs to ellipsoidal variables as deduced from the Roche lobe geometry. For photometric analysis, we used the PHOEBE software package, which is based on the Wilson-Devinney code. Due to lack of spectroscopic data, the photometric mass ratios are determined from the analyses of light curves using the q-search method. The absolute parameters are determined using three different methods(Harmanec, maceroni &Van'tVeer and Gazeas & Niarchos).
