Studies on the vapour-transport synthesis and electrochemical properties of zinc micro-, meso- and nanoscale structures

Journal of Materials Chemistry (2006)

Hua Ma Chunsheng Li Yi Su Jun Chen

In this paper, we report the syntheses of zinc micro/meso/nanoscale spheres and needles via a vapour-transport deposition process and their electrochemical properties as anode active materials for alkaline Zn–MnO2 batteries. The instrumental analysis showed that the zinc microspheres presented uniform polyhedral morphology with the diameter of approximately 1–3 µm; the mesoscale spheres were around 150 nm in diameter, and the nanoneedles grew towards the upper end of the nano domain to form a porous network structure with a nanoneedle length of more than 100 nm. The electrochemical investigation indicated that the vapour-deposited zinc, and in particular the mixture of zinc micro- and mesoscale spheres exhibited superior electrochemical properties due to the decrease of the charge transfer resistance and the suppression of passivation of the zinc electrode, resulting in the improvement of the electrochemical performance of the alkaline Zn–MnO2 battery.

Metallic Magnesium Nano/Mesoscale Structures: Their Shape‐Controlled Preparation and Mg/Air Battery Applications

Angewandte Chemie International Edition (2006)

Weiyang Li Chunsheng Li Chunyuan Zhou Hua Ma Jun Chen

Magnesium nano/mesostructures with spherical, platelike, rodlike, and sea-urchin-like shapes are prepared by a simple and efficient vapor-transport method. They exhibit excellent electrochemical properties in Mg/air batteries. The figure shows discharge curves of the Mg/air batteries made from two samples, at a constant current of 0.5 mA and a temperature of 25 °C.

Ni_1-_xPt_x (x = 0−0.12) Hollow Spheres as Catalysts for Hydrogen Generation from Ammonia Borane

Inorganic Chemistry (2007)

Fangyi Cheng Hua Ma Yueming Li Jun Chen

In this paper, nest-like Ni1-xPtx (x = 0, 0.03, 0.06, 0.09, and 0.12) hollow spheres of submicrometer sizes have been prepared through a template-replacement route and investigated as catalysts for generating hydrogen from ammonia borane (NH3BH3). Experimental investigations have demonstrated that the obtained Ni1-xPtx alloy hollow spheres exhibit favorable catalytic activities for both the hydrolysis and the thermolysis of NH3BH3. It was found that, in the presence of the Ni0.88Pt0.12 catalyst, the hydrolysis of NH3BH3 causes a quick release of H2, while the thermal decomposition of NH3BH3 occurs at lowered temperatures with increased mass loss. The present results indicate that NH3BH3 along with Ni1-xPtx alloy hollow spheres may find some applications for small-scale on-board hydrogen storage and supply.

Magnesium Nanowires: Enhanced Kinetics for Hydrogen Absorption and Desorption

Journal of the American Chemical Society (2007)

Weiyang Li Chunsheng Li Hua Ma Jun Chen

Mg nanowires with the diameters of 30−50 nm, 80−100 nm, and 150−170 nm, which were prepared via a vapor-transport method, exhibited enhanced kinetics for hydrogen absorption/desorption. The present results clearly show that thinner Mg/MgH2 nanowires have a much lower desorption energy than that of thicker nanowires or bulk Mg/MgH2, indicating that changes in kinetics and thermodynamics are expected if the diameters of the nanowires are thinner than 30 nm.

Novel B-Doped Feni/C Alloy Nanofibers Electrocatalyst for Efficient Oxygen Evolution Reaction from Water Splitting

Zhijian Peng Hua Ma Xiuli Fu Xiu-Wen Wu

Industrial-scale water splitting processes will require economical and efficient electrocatalyst materials. Many oxygen evolution electrocatalysts prepared with non-precious metals have been reported. However, transition metal-based nanomaterials experience unavoidable aggregation and low stability in corrosion environments, which substantially reduces their catalytic performance. Herein, we successfully used a simple electrospinning technique followed by carbonation to synthesize a porous B-doped carbon fiber electrocatalyst with embedded B-doped FeNi alloy nanoparticles. To prepare the optimal catalyst sample, 1.05 g PAN, 5.0 mmol H3BO3, 2.5 mmol Fe(NO3)3, and 2.5 mmol Ni(NO3)2 were used as precursors. The electrospun pristine fibers were annealed for 1 h at 800 ̊C in argon. Its overpotential for oxygen evolution at a current density of 10 mA·cm-2 was only 231 mV, and a 47.57 mV·dec-1 Tafel slope was achieved. At this current density, this catalyst exhibits good performance for over 24 h or for more than 1000 CV cycles. This is due to the doping of non-metallic B atoms into the alloy nanoparticles, as well as the support and protection on them by carbon nanofibers. insight This research provides a more thorough understanding of the preparation and practical application of low-cost and high-efficiency transitional metal alloy based water splitting catalysts.
