“…4e), indicating the formation of highly coordinated quaternary 'pyrrolic' N atoms (400.6 eV) incorporated into graphene sheets, along with pyridine-like N atoms incorporated into graphene sheets (398.7 eV). [27] As shown in Fig. 4d, the C 1s spectrum of the samples exhibits a main peak at 284.9 eV, consistent with sp 2 carbon.…”

“…typical rhombic dodecahedron morphology with an average particle size of 100-150 nm. [27] After carbonization process either in Ar or in steam atmosphere, as presented in Fig. 7, all the ZnO/C composites exhibit spherical-like particles with shrank sizes around 100-130 nm but the small particles tend to agglomeration to form larger particles.…”

“…The final product was collected from the quartz tube and labelled as ZnO/C-S-S. Another sample was also obtained via the similar one-step direct carbonization process where a 20 ml/min of argon flow saturated with water vapour is constantly presented during the heating up step, the maintaining at the target temperature for 3 h and the cooling down to room temperature. This sample was designed as ZnO/C-S-L. For comparison, the one-6 step process was also applied to the annealing of ZIF-8 at 800 o C for 3 h under argon atmosphere with a flow rate of 20 ml/min, [27] and the collected samples was named as ZnO/C-A. A pure ZnO was also obtained via annealing of ZIF-8 in air at 800 o C for 3 h.…”

“…However, the sample derived from the carbonization in argon (sample ZnO/C-A) displays no peaks from ZnO, which is consistent with our previous observation. [27] Clearly the carbonization atmosphere has significant effect on the resulting composites. In addition, all the ZnO/C composites exhibit a broad XRD peak centred at the 2θ of 25 o due to the (002) diffraction of carbon, indicating that the utilization of water vapour atmosphere does not damage the formation of porous carbon from ZIF-8 precursors.…”

“…[25] Most recently, we utilized a typical sodalite topology ZIF-8, which is built from corner-shared tetrahedral ZnN 4 units and the coordination bonds between the Zn 2+ ions and 2-methylimidazole anions that are amongst the most stable N-donor ligands, [26] to synthesize ZnO/porous carbon composites by the direct carbonization in argon atmosphere, but no XRD peaks related to either ZnO or Zn can be observed in these composites. [27] Therefore, designing new synthesis strategies to create efficient porous carbon-metal oxide composites is highly desirable.…”

Advanced functional composite of ZnO nanoparticles embedded in N-doped nanoporous carbons has been synthesized by a simple one-step carbonization of zeolitic imidazolate framework-8 under a water stream atmosphere. A variety of characterization techniques show that the introduction of water steam during the carbonization process holds the key to obtain the fine and homogeneously dispersed ZnO nanoparticles within the functionalised nanoporous carbon matrix. Possessing a higher specific surface area, a larger pore volume and abundant oxygen-containing hydrophilic functional groups, the resulting composite exhibits a stronger interaction with CO 2 and is more efficient to promote the photocatalytic degradation-adsorption of methylene blue under visible light than the composite obtained without steam treatment. As a result, the steam derived composite exhibits increased CO 2 uptake capacity and excellent methylene blue molecules removal from water. Using different metal-organic frameworks as precursors, this new, simple and green method can be further expanded to generate various new homogeneous dispersed functional metal oxide/porous carbon composites with high efficient in relevant applications.

Porous carbon materials have demonstrated exceptional performance in a variety of energy-and environment-related applications. Over the past decades, tremendous efforts have been made in the coordinated design and fabrication of porous carbon nanoarchitectures in terms of pore sizes, surface chemistry, and structure. Herein, structure-oriented carbon design and applications are reviewed. The unique properties of porous carbon materials that offer them promising design opportunities and broad applicability in some representative fields, including water remediation, CO 2 capture, lithium-ion batteries, lithium-sulfur batteries, lithium metal anodes, Na-ion batteries, K-ion batteries, supercapacitors, and the oxygen reduction reaction are highlighted. Then, the most up-to-date strategies for structural control and functionalization of porous carbons are summarized, toward tailoring microporous, mesoporous, macroporous, and hierarchically porous carbons with disordered or ordered, amorphous or graphitic structures. Meanwhile, the emerging features of these structures in various applications are introduced where applicable. Finally, insights into the challenges and perspectives for future development are provided.

High‐Energy Efficiency Membraneless Flowless Zn–Br Battery: Utilizing the Electrochemical–Chemical Growth of Polybromides

et al. 2019

Aqueous Zn–Br batteries (ZBBs) offer promising next‐generation high‐density energy storage for energy storage systems, along with distinctive cost effectiveness particularly in membraneless and flowless (MLFL) form. Unfortunately, they generally suffer from uncontrolled diffusion of corrosive bromine components, which cause serious self‐discharge and capacity fade. An MLFL‐ZBB is presented that fundamentally tackles the problem of bromine crossover by converting bromine to the polybromide anion using protonated pyridinic nitrogen doped microporous carbon decorated on graphite felt (NGF). The NGF electrodes efficiently capture bromine and polybromide anions at the abundant protonated nitrogen dopant sites within micropores and facilitate effective conversion of bromine into polybromides through electrochemical–chemical growth mechanism. The MLFL‐ZBBs with NGF exhibit an extraordinary stability over 1000 charge/discharge cycles, with an energy efficiency over 80%, the highest value ever reported among membraneless Zn–Br batteries. Judicious engineering of an atomistically designed nanostructured electrode offers a novel design platform for low cost, high voltage, long‐life cycle aqueous hybrid Zn–Br batteries.
