This book was released on 2015 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlling the structure of inorganic materials on the mesoscale (2-50 nm) is desirable for many applications and can influence the materials' properties and performance in devices. Amphiphilic block copolymers (BCPs) have been used extensively to structure-direct transition metal oxides, controlling their mesoscale morphology. By selectively incorporating metal oxide precursors into one block of the BCP and removing the BCP through thermal decomposition, ordered mesoporous metal oxides with well-defined mesoscale morphologies can be achieved that are interesting, e.g. for energy conversion and storage applications. This dissertation reports on the amphiphilic block terpolymer poly(isoprene)-blockpoly(styrene)-block-poly(ethylene oxide) used in combination with sol-gel metal oxide precursors to generate ordered three-dimensionally (3D) mesoporous metal oxides. 3D cocontinuous cubic network structures such as the alternating gyroid are particularly interesting for energy applications due to their chirality, co-continuity, and high porosity. In particular, the high porosity and mesoscale dimensions can facilitate rapid diffusion of gases/liquids, but limit solid state diffusion lengths in the inorganic structure during chemical conversions of the oxides, e.g. nitriding. Freestanding gyroidal mesoporous metal oxides can be further processed into gyroidal mesoporous metal nitrides by heating under flowing ammonia gas. Transition metal nitrides are of interest due to their electrical conductivity and electrochemical stability. The development of a synthesis for 3D ordered mesoporous nitrides opens paths for studying the effects of welldefined block copolymer mesostructures on superconductivity, an exciting new field.

Book excerpt: Nanostructured materials with tailored properties are regarded as a fundamental element in the development of future science and technology. Research is still ongoing into the nanosized construction elements required to create functional solids. The recently developed technique, nanocasting, has great advantage over others in terms of the synthesis of special nanostructured materials by the careful choice of suitable elements and nanoengineering steps. This new book summarizes the recent developments in nanocasting, including the principles of nanocasting, syntheses of novel nanostructured materials, characterization methods, detailed synthetic recipes and further possible development in this area. The book focuses on the synthesis of porous solids from the viewpoint of methodology and introduces the science of nanocasting from fundamental principles to their use in synthesis of various materials. It starts by outlining the principles of nanocasting, requirements to the templates and precursors and the tools needed to probe matter at the nanoscale level. It describes how to synthesize nano structured porous solids with defined characteristics and finally discusses the functionalization and application of porous solids. Special attention is given to new developments in this field and future perspectives. A useful appendix covering the detailed synthetic recipes of various templates including porous silica, porous carbon and colloidal spheres is included which will be invaluable to researchers wanting to follow and reproduce nanocast materials. Topics covered in the book include: * inorganic chemistry * organic chemistry * solution chemistry * sol-gel and interface science * acid-base equilibria * electrochemistry * biochemistry * confined synthesis The book gives readers not only an overview of nanocasting technology, but also sufficient information and knowledge for those wanting to prepare various nanostructured materials without needing to search the available literature.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It was the goal of this work to explore two different synthesis pathways using green chemistry. The first part of this thesis is focusing on the use of the urea-glass route towards single phase manganese nitride and manganese nitride/oxide nano-composites embedded in carbon, while the second part of the thesis is focusing on the use of the “saccharide route” (namely cellulose, sucrose, glucose and lignin) towards metal (Ni0), metal alloy (Pd0.9Ni0.1, Pd0.5Ni0.5, Fe0.5Ni0.5, Cu0.5Ni0.5 and W0.15Ni0.85) and ternary carbide (Mn0.75Fe2.25C) nanoparticles embedded in carbon. In the interest of battery application, MnN0.43 nanoparticles surrounded by a graphitic shell and embedded in carbon with a high surface area (79 m^2/g) were synthesized, following a previously set route.The comparison of the material characteristics before and after the discharge showed no remarkable difference in terms of composition and just slight differences in the morphological point of view, meaning the particles are stable but agglomerate. The graphitic shell ...

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The research work presented here is focused on nanotechnological synthetic approaches for transition metal oxide nanomaterials and their applications in heterogeneous catalysis and adsorptive desulfurization reactions. Here, we discuss the controllable synthesis of functional nanomaterials and investigation of their structure-activity relationship in multiphase catalytic and sorption reactions. Among transition metal oxides, Co3O4 is well known for the presence of mobile oxygen, and thus is more reactive towards oxidation reactions. Aerobic oxidation under additive free conditions is highly desirable in organic synthesis reactions, from the viewpoint of green and sustainable chemistry. We demonstrate the activity enhancement of mesoporous cobalt oxide materials by substitutional doping of molybdenum ions. We discuss the surface chemistry in the production of active metal oxide nanoparticles and effect of lattice deformation on creating surface defects. High conversion and selectivity was achieved by controlling the surface area, Lewis acidity, and oxygen vacancy density of the solid catalyst in the liquid phase dehydrogenative coupling reactions. Synthesis of high surface area mesoporous cobalt molybdenum mixed metal oxide materials was accomplished using surfactant assisted inverse micelle method. The cobalt molybdenum oxide materials were investigated as a efficient desulfurization sorbent in a fixed bed reactor at low temperatures ( C).
