“…Unlike thin films, the formation of Co-Sb nanowires involves three main processes that take into consideration the template characteristics. 20 First, Co 2+ and SbO + ions are driven by both electric field and concentration gradient into the nanopores of the template, while the diffusion of HSbO 2 is only influenced by its concentration gradient. The charge applied to the electrode surface provides the electrons to produce elemental Co and Sb (reactions 4 and 5).…”

Co-Sb thin films and nanowires were grown on gold-coated polymer templates by electrochemical deposition under different potentiostatic conditions from -0.8 to -1.0 V vs Ag/AgCl. The growth of nanowires was 3D and went through several growth stages starting from the gold-coated wall. Overgrowth of nanowires out of the porous template did not produce a fully dense film; instead, Sb-rich columnar structures (mushroom caps) were developed and connected by Co-rich needle-like structures. Compared to nanowires, the mushroom caps had a lower content of Co. With a more negative deposition potential, the content of Co in the nanowires and the mushroom caps increased. A composition of Co:Sb ) 1:3 in nanowires was obtained at a constant deposition potential of -0.965 V.

“…Skutterudites have a large interstitial void that can play host to "rattler dopants" [406] which may be used to selectively scatter phonons; these materials therefore provide the opportunity to combine rattler scattering and confinement effects for a potentially significant increase in zT above the bulk value. The growth of CoSb 3 nanowires via electrodeposition has been demonstrated [163,407] and it is predicted that similar enhancement of zT from confinement effects should be observed [163,408], though this has yet to be experimentally verified. In all of the above classes of material, careful control of feature size is paramount to both understanding and controlling the size effects that lead to enhanced thermoelectric performance, be it quantum confinement and band structure modification, enhanced phonon scattering, or other effects.…”

A variety of nanostructured materials are produced through template-based synthesis methods, including zerodimensional, one-dimensional, and two-dimensional structures. These span different forms such as nanoparticles, nanowires, nanotubes, nanoflakes, and nanosheets. Many physical characteristics of these materials such as the shape and size can be finely controlled through template selection and as a result, their properties as well. Reviewed here are several examples of these nanomaterials, with emphasis specifically on the templates and synthesis routes used to produce the final nanostructures. In the first section, the templates have been discussed while in the second section, their corresponding synthesis methods have been briefly reviewed, and lastly in the third section, applications of the materials themselves are highlighted. Some examples of the templates frequently encountered are organic structure directing agents, surfactants, polymers, carbon frameworks, colloidal sol-gels, inorganic frameworks, and nanoporous membranes. Synthesis methods that adopt these templates include emulsion-based routes and template-filling approaches, such as self-assembly, electrodeposition, electroless deposition, vapor deposition, and other methods including layer-by-layer and lithography. Templatebased synthesized nanomaterials are frequently encountered in select fields such as solar energy, thermoelectric materials, catalysis, biomedical applications, and magnetowetting of surfaces.
