This book was released on 2018 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Electrocatalytic water splitting is a promising solution for sustainable energy generation since one of the half reactions lead to the formation of H2 which is a clean fuel. The other half of the reaction leading to O2 evolution is an energy intensive process necessitating the need for an electrocatalyst to break the activation barrier for the commencement of the reaction. In this work we will focus on expanding the family of non-oxidic OER electro-catalysts, especially borides, whereby, apart from facilitating delocalization of electron cloud on the catalytically active transition metal site, low anion electronegativity and increased covalency in the lattice compared to oxides, is expected to facilitate the catalytic process. Analyzing these properties, amorphous nickel boride (Ni3B) was chosen and synthesized through a room temperature chemical conversion technique. Characterization of the synthesized material confirmed that the as-prepared Ni3B was nanocrystalline with particles in the range of 50 - 60nm. Ni3B showed high efficiency for electrocatalytic O2 evolution under alkaline conditions exhibiting a low onset potential and overpotential (ɳ) of 340 mV @ 10 mAcm−2. Ni3B was further incorporated into a matrix of reduced graphene oxide to improve the catalytic performance by facilitating charge transfer within the catalytic matrix since its incorporation increases conductivity of the catalytic film. As expected, Ni3B-reduced graphene oxide nanocomposite showed an improved catalytic performance compared to Ni3B nanostructures with onset potential lower by 70mV and ɳ of 290 mV @ 10mAcm−2. The OER catalytic performance obtained with Ni3B and nanocomposite was observed to be significantly better than the conventionally used noble metal oxides such as RuO[sub x], and was comparable to some of the best OER electrocatalysts"--Abstract, page iv.

This book was released on 2016 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is still a challenging task to develop simple methods for facile synthesis of functional nanostructures on substrates under mild conditions without using expensive instruments. We have successfully developed a bio-inspired method using simple diaphragm-assisted system to synthesize functional nanostructures on various substrates under mild conditions. We have systematically studied the effects of experimental parameters on the formation of nanostructures under controlled conditions. The fundamental mechanism involved has been systematically studied and revealed. By growing the unique networks of nanostructures on a piece of substrate, a double-rough surface, with structures at both nanoscale and microscale, has been achieved, showing interesting roughness-induced superhydrophobicity in air and superoleophobicity in water. The double rough substrates will find important environmental applications. Additionally, nanostructures formed on substrates have been used as integrated and binder-free electrodes for energy storage. The unique structures with a large exposed surface enable the electrodes to demonstrate dramatically improved performances. Moreover, some chemically active substrates were used to build up composite materials to enhance their applications. The method and ideas outlined in the dissertation, based on diaphragm-assisted systems, will have impacts, in principle, on the synthesis of numerous functional materials or precursors under mild conditions.

Book excerpt: Environmental pollution and energy crisis are two of the major obstacles in the development of a more sustainable society. It is an interesting but technically challenging task to design novel methods for the facile and scalable synthesis of multifunctional materials for applications in both energy storage and environmental remediation. In this thesis, I tried to design and synthesize novel nanostructured materials for energy and environmental applications, achieved highly promising results. I developed a facile electrochemical approach to synthesize the zinc oxide with the zinc element for photocatalytic reactions. It demonstrated dramatically improved performances in degradation of organic pollutant in water, using a dye as a model. In another effort, I tried to develop integrated electrode materials for highly stable and high-energy cathodes for lithium batteries. The as-prepared Fe-V based cathode materials can be cycled over 100 cycles delivery a relatively high capacity of 200 mAh/g. The encouraging results revealed that further research should be carried out.
