Surface/interface Nanoengineering for rechargeable Zn–air batteries
Energy & Environmental Science, 2020Co-Authors: Tianpei Zhou, Nan Zhang, Yi XieAbstract:Among the various energy storage systems, the rechargeable Zn–air battery is one of the most promising candidates for the consumer electronic market and portable energy sources. In a Zn–air battery, surface/interface chemistry plays a key role in their performance optimization of power density, stability and rechargeable efficiency. A Zn–air battery requires gas-involved ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) reactions, always leading to complex reactions and sluggish kinetic processes at the three-phase interface, in which rational surface/interface Nanoengineering at the micro and meso-level play a decisive role. In this review, we cover the influence of surface/interface properties of electrocatalysts and air electrodes on the performance of rechargeable Zn–air batteries, and the latest surface/interface Nanoengineering progress from the micro to meso-level is surveyed. Moreover, the surface/interface characteristics of electrocatalysts and air electrodes at the triple-phase interface, which are closely related to the four key parameters of electrical conductivity, reaction energy barrier, reaction surface area and mass transfer behavior, are also described in detail. Based on the discussion of the latest achievements of surface/interface Nanoengineering, some personal perspectives on future advanced development of rechargeable Zn–air batteries are presented as well.

Nanoengineering-Enabled Solid-State Hydrogen Uptake and Release in the LiBH4+MgH2 System
The Journal of Physical Chemistry C, 2008Co-Authors: Xuefei WanAbstract:LiBH 4 , as a potential material with the highest reversible hydrogen storage capacity for hydrogen vehicle applications, has always been hydrogenated and dehydrogenated in the liquid state. In this study, we demonstrate, for the first time, that 8.3 wt % hydrogen uptake can be obtained from the LiBH 4 + MgH 2 system in the solid state through Nanoengineering and mechanical activation. Hydrogen release, although slower than uptake, can also be attained in the solid state. All of these enhancements are achieved without any catalysts, which underscores the effectiveness of Nanoengineering and mechanical activation as well as the opportunity for further improvements in the future.

Nanoengineering Particles through Template Assembly
Chemistry of Materials, 2016Co-Authors: Mattias Björnmalm, Jiwei Cui, Nadja Bertleff-zieschang, Danzi Song, Matthew Faria, Arifur Rahim, Frank CarusoAbstract:The Nanoengineering of particles is of interest for both fundamental and applied science. How particles are made substantially affects their properties and quality, and therefore usefulness. Disseminating current understanding of particle engineering can help facilitate the use of existing technologies, as well as guide future developments. Herein, we describe three methods used in our laboratory for the Nanoengineering of particles, based on template assembly, and discuss important considerations for each. First, we describe the use of layer-by-layer assembly for depositing multilayered nanofilms on particle surfaces to generate core–shell particles and hollow capsules. Second, we detail the use of mesoporous silica templating for the engineering of porous polymer replica particles. Third, we describe how the coordination of phenolic compounds and metal ions can be used to fabricate thin films via metal–phenolic network formation on particle templates. We provide stepwise, easy-to-follow guides for each ...

Nanoengineering of particle surfaces
Advanced Materials, 2001Co-Authors: Frank CarusoAbstract:The creation of core–shell particles is attracting a great deal of interest because of the diverse applicability of these colloidal particles; e.g., as building blocks for photonic crystals, in multi-enzyme biocatalysis, and in drug delivery. This review presents the state-of-the-art in strategies for engineering particle surfaces, such as the layer-by-layer deposition process (see Figure), which allows fine control over shell thickness and composition.
