      Wet spinning of graphene oxide liquid crystal exploits 1D conductive catalyst support and electrochemical deposition realizes successful hybridization with amorphous molybdenum sulfide. Geometrical advantage of reduced graphene oxide (RGO) fiber can hold larger amount of amorphous molybdenum sulfide and optimized loading on RGO fiber provides high catalytic activity and stability for hydrogen evolution reaction.

      The transmission efficiency can be significantly enhanced in a sandwiched film in comparison with that of a single continuous metal film.

    1. Aluminum-Based Plasmonic Photocatalysis

      Yan Chen, Xin Xin, Nan Zhang and Yi-Jun Xu

      Version of Record online: 25 JAN 2017 | DOI: 10.1002/ppsc.201600357

      Aluminum (Al) unfolds outstanding light-harvesting capacity and performance in virtue of its unique optical characteristics, which are enabled by a localized surface plasmon resonance (LSPR) effect. Based on these properties, Al as a cost-efficient emerging material opens up an avenue with the significant utilization of solar energy toward plasmon-enhanced photocatalysis.

    1. Strain Mediated Bandgap Reduction, Light Spectrum Broadening, and Carrier Mobility Enhancement of Methylammonium Lead/Tin Iodide Perovskites

      Yalong Jiao, Fengxian Ma, Hongxia Wang, John Bell and Aijun Du

      Version of Record online: 24 JAN 2017 | DOI: 10.1002/ppsc.201600288

      Thumbnail image of graphical abstract

      Density functional theory calculations are performed to study the electronic and optical properties of methylammonium lead/tin iodide perovskites under hydrostatic strain. It is found that the bandgap is significantly reduced in lead/tin iodide perovskites under a moderate strain. Such bandgap narrowing consequently induces the redshift of light absorption spectrum and lightens the electron effective mass for CH3NH3PbI3/CH3NH3SnI3.

    1. In Operando Self-Healing of Perovskite Electrocatalysts: A Case Study of SrCoO3 for the Oxygen Evolution Reaction

      Hassan A. Tahini, Xin Tan, Udo Schwingenschlögl and Sean C. Smith

      Version of Record online: 24 JAN 2017 | DOI: 10.1002/ppsc.201600280

      Thumbnail image of graphical abstract

      Perovskites are promising catalysts for oxygen evolution reactions (OER); among them, SrCoO3 is one of the best for these reactions. We study the O* intermediates and the role of surface oxygen vacancies of SrCoO3 during OER. A self-healing mechanism is proposed in which O* are incorporated into the surface to recover the redox capabilities of the material.

    1. Size-Tunable Synthesis of Hollow Gold Nanospheres through Control of Reaction Temperature

      Ying-Chih Pu, Frank Song, Weichun Zhang, Sarah Lindley, Staci Adams and Jin Z. Zhang

      Version of Record online: 27 DEC 2016 | DOI: 10.1002/ppsc.201600255

      A facile synthesis is reported for modulating the diameter of hollow gold nanosphere (HGN) from 24 to 122 nm through controlling the reaction temperature of cobalt scaffold. The resultant diameter of HGNs affects its surface plasmon resonance that spans from the visible into the Near IR.

    1. Hierarchical Porous Yolk–Shell Carbon Nanosphere for High-Performance Lithium–Sulfur Batteries

      Tianyu Yang, Yijun Zhong, Ji Liang, Md Mokhlesur Rahman, Weiwei Lei, Ying Chen, Michael J. Monteiro, Zongping Shao and Jian Liu

      Version of Record online: 23 DEC 2016 | DOI: 10.1002/ppsc.201600281

      Thumbnail image of graphical abstract

      A hierarchical structured carbon nanosphere with a mesoporous yolk and a microporous shell is applied for Li–S batteries. The yolk hosts a high content of sulfur and the core blocks the soluble polysulfide from migrating outside. This unique structure has rendered a high capacity, good rate performance, as well as a very stable cyclability for Li-S batteries.

    1. Enhancing the Photoactivity of Faceted BiVO4 via Annealing in Oxygen-Deficient Condition

      Hui Ling Tan, Adrian Suyanto, Alexandra T. De Denko, Wibawa H. Saputera, Rose Amal, Frank E. Osterloh and Yun Hau Ng

      Version of Record online: 23 DEC 2016 | DOI: 10.1002/ppsc.201600290

      Thumbnail image of graphical abstract

      Argon annealing is demonstrated to not only enhance the crystallinity, local structure distortion, and photon absorption of dual-faceted BiVO4 but also shown to induce the creation of oxygen vacancies. The extent of enhancement of these properties is dependent on the annealing temperature, which can lead to improved charge separation, transport, and photoactivity of the BiVO4.

    2. Synthesis of Magnesium Nanofibers by Electroless Reduction and their Hydrogen Interaction Properties

      Yahui Sun and Kondo-Francois Aguey-Zinsou

      Version of Record online: 20 DEC 2016 | DOI: 10.1002/ppsc.201600276

      Thumbnail image of graphical abstract

      Magnesium nanofibers are successfully synthesized through the direct reduction of dibutylmagnesium by calcium in the presence of 1-dodecanethiol. This magnesium nanofibers show fast absorption kinetics and remarkably retain their morphology even under hydrogen cycling.

    3. A General Approach to the Synthesis of M@Au/Ag (M = Au, Pd, and Pt) Nanorattles with Ultrathin Shells Less Than 2.5 nm Thick

      Miaoxin Yang, Kyle D. Gilroy and Younan Xia

      Version of Record online: 10 NOV 2016 | DOI: 10.1002/ppsc.201600279

      Thumbnail image of graphical abstract

      M@Au/Ag (M = Au, Pd, and Pt) nanorattles with sizes as small as 15 nm have been successfully prepared by depositing an ultrathin Au shell prior to the galvanic replacement reaction to greatly enhance the mechanical strength of the nanorattles. The small Au@Au/Ag nanorattles can be made with strong absorption in the near-infrared for photothermal cancer therapy.
