“…3b, d and f), the typical nanofibrous structures of the immobilized samples with uniform morphology are clearly evident, and this unique nanofibrous structure material is well depicted with FE-SEM and TEM measurements in our previous papers [16,18]. Furthermore, the BET surface areas were calculated to be 15 (Table 1). It was worth noting that CNFs template method is a facile and economy fabrication technique for novel material formation on the substrate surface, and the resulting asprepared materials basically duplicate the shapes of CNFs templates.…”

“…Along with cellulosic nanofibers, carbon nanofibers are widely used to template a variety of inorganic nanotubes as well, including ZrO 2 , Al 2 O 3 , and SiO 2 [146], and then removed through calcination at elevated temperatures (1023 K) TiO 2 [147] and SnO 2 nanotubes [147] produced using carbon nanofibers are highly similar to those produced from cellulose templates. Polymeric fibers and other natural organic species can also be used as thermally removable templates.…”

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.

“…The same method is also applicable for the synthesis of ZrO 2 and Al 2 O 3 nanotubes. [74] Peptide amphiphile (PA) nanofibres have been successfully used as templates. The catalytic activities of PAs that contain lysine, histidine, or glutamic acid have been compared and only the PAs that contain lysine or histidine found to be good as catalytic templates.…”

Nanotubes constitute an exciting class of one‐dimensional nanomaterials of which carbon nanotubes are recognized widely as materials of importance. The possibility of having inorganic nanotubes was recognized early in the 1990s, accompanied by the report of nanotubes of MoS2 and WS2. Since then, nanotubes of several inorganic materials have been prepared and characterized. While nanotubes of metal chalcogenides and oxides form a high proportion of the inorganic nanotubes investigated hither to, nanotubes of many other materials have also been prepared and characterized. Several synthetic strategies including both physical and chemical methods have been employed, of which the use of templates, precursors, and hydro‐ or solvothermal methods are prominent. In this article, we shall present a brief account of the present status of the synthesis of nanotubes of elemental materials as well as binary and complex metal oxides, chalcogenides, pnictides and carbides.
