Zno Nanocarbon Core Shell Type Hybrid Quantum Dots

eBook Download

BOOK EXCERPT:

This book offers a comprehensive overview of ZnO-nano carbon core shell hybrid issues. There is significant interest in metal oxide/nanocarbon hybrid functional materials in the field of energy conversion and storage as electrode materials for supercapacitors, Li ion secondary battery, electrocatalysts for water splitting, and optoelectronic devices such as light emitting diodes and solar photovoltaic cells. Despite efforts to manipulate more uniform metal oxide-nanocarbon nanocomposite structures, they have shown poor performance because they are randomly scattered and non-uniformly attached to the nanocarbon surface. For higher and more effective performance of the hybrid structure, 3D conformal coating on metal oxides are highly desirable. In the first part of the book, the physical and chemical properties of ZnO and nanocarbons and the state-of-the-art in related research are briefly summarized. In the next part, the 3D conformal coating synthetic processes of ZnO templated nanocarbon hybrid materials such as ZnO-graphene,-C60, single-walled (SWCNT) are introduced with the aid of schematic illustrations. Analysis of their chemical bonding and structure are also presented. In the final section, several applications are presented: UV photovoltaic cells and photoelectrochemical anodes for water splitting using ZnO-C60 and ZnO-graphene, white-light-emitting diodes based on ZnO-graphene quantum dots(GQDs), inverted solar cells using ligand-modified ZnO-graphene QDs, and P(VDF-TrFE) copolymer with mixed with nano-ring SWCNT. The book describes how strong anchoring bonds between a ZnO core and carbon nanomaterial shell will ultimately prevail over the main drawbacks of ZnO with high charge recombination and poor electrochemical stability in liquid solutions. Due to the moderate energy states and excellent electric properties of the nanocarbons, ultrafast charge carrier transport from the ZnO core to the nanocarbon shell is guaranteed with the use of the photoluminescence (PL) lifetime measurement. Given the growing interest and significance of future research in optoelectronic and electrochemical devices applications, the contents are very timely. This book is targeted towards researchers looking for highly efficient metal oxide-nanocarbon hybrid functional materials in the fields of nano-optoelectronics, photoelectrochemistry, energy storage and conversion.

Hybrid Nanomaterials

eBook Download

BOOK EXCERPT:

The book highlights applications of hybrid materials in solar energy systems, lithium ion batteries, electromagnetic shielding, sensing of pollutants and water purification. A hybrid material is defined as a material composed of an intimate mixture of inorganic components, organic components, or both types of components. In the last few years, a tremendous amount of attention has been given towards the development of materials for efficient energy harvesting; nanostructured hybrid materials have also been gaining significant advances to provide pollutant free drinking water, sensing of environmental pollutants, energy storage and conservation. Separately, intensive work on high performing polymer nanocomposites for applications in the automotive, aerospace and construction industries has been carried out, but the aggregation of many fillers, such as clay, LDH, CNT, graphene, represented a major barrier in their development. Only very recently has this problem been overcome by fabrication and applications of 3D hybrid nanomaterials as nanofillers in a variety of polymers. This book, Hybrid Nanomaterials, examines all the recent developments in the research and specially covers the following subjects: 3D hybrid nanomaterials nanofillers Hybrid nanostructured materials for development of advanced lithium batteries High performing hybrid nanomaterials for supercapacitor applications Nano-hybrid materials in the development of solar energy applications Application of hybrid nanomaterials in water purification Advanced nanostructured materials in electromagnetic shielding of radiations Preparation, properties and application of hybrid nanomaterials in sensing of environmental pollutants Development of hybrid fillers/polymer nanocomposites for electronic applications High performance hybrid filler reinforced epoxy nanocomposites State-of-the-art overview of elastomer/hybrid filler nanocomposites
