The work covered herein discusses for the first time various techniques used in the fabrication of metal oxide nanofibers and nanotubes from eletrospun carbon fibers as templates. The nanofibers were prepared by electrospinning metal oxide precursor inside a polymer matrix. The metal oxide tubes were by tubes by fiber templating. This was followed by calcination to yield the nanofibers and nanotubes. Their morphological, structural, optoelectronic and catalytic properties are also discussed. Among key applications they have found utilization as catalyst supports. Palladium nanoparticles have been supported on Titanium dioxide nanofibers and applied in Heck-coupling reactions. Similarly, included is the effect of impurities on the metal oxide tubes properties done by doping with metal ions. In addition, photocatalytic behavior of metal oxides nanofibers have also been discussed.

This book puts forward a catalyst-free CVD approach for fabricating CNTs with totally controlled properties (e.g. geometry, shape, chemical composition, surface chemistry, etc.) by using nanoporous templates with well-defined chemistry and geometry from recycled plastic bags. As a result of its simplicity, versatility, scalability and cost-competitive fabrication process, this approach is envisaged for producing CNTs featuring standardized properties, which are required for a broad range of applications (e.g. separations, drug delivery, etc.). To develop this CVD approach, the optimal conditions for the fabrication of catalyst-free CNTs were determined by varying such parameters as temperature, reaction path length, absence or presence of catalyst, type of nanoporous template (i.e. nanoporous anodic alumina (NAA) or titania nanotubes (TNTs)) and type of carbon source.

Recently, porous ceramic materials are used as components in special and advanced engineering applications. These include filtering liquids and particles in gas streams, porous burners, biomedical devices, lightweight load-bearing structures, sandwich panels, core materials, heat insulation, fuel cell, as conductor as well as insulator, etc. Fabrications of open cell ceramic foams are of scientific and technological interest because of their ability to interact with atoms, ions and molecules not only at their surface, but throughout the bulk of the material. In present review, the three basic methods (i.e. replica, direct foaming and burn-out of fugitive route) for preparing ceramic foams are discussed. Highly-porous and interconnected carbon foams were manufactured via template route. The porous silica foams are obtained through a sintering of macro-casted PU foam templates with the hydrolyzed silica sol. Both the foams were highly interconnected having uniform porosity and pore size distribution.
