Templated carbons unique pore structure

This kind of carbon with such unique pore structure, extremely large surface area, and micropore volume has never been reported. Sections 3.3.3.1 and 3.3.3.2 will introduce the details of the production method of the ordered microporous carbons and compare the extraordinary pore structure of this carbon with commercial microporous carbons with a large surface area. In Section 3.3.3.3, it will be demonstrated that a similar ordered microporous carbon containing N atoms can be prepared by the template technique, and the N-doping influences the adsorption behavior of H20 molecules [136], In Section 3.3.3.4, the use of this unique carbon as an electrode for supercapacitor will be introduced [137],... [Pg.96]

Strategy for making materials with desired characteristics provides opportunities to substantially improve electrochemical energy conversion. Template-synthesized carbon materials have proved their unique performances in lithium-ion batteries, electrical double-layer capacitors (EDLCs), and fuel cells because of their surface chemistry, pore structure, and electrical conductivity characteristics. [Pg.112]

Because of the uniquely ordered structure of template-synthesized porous carbons, they themselves can be used as templates to replicate other materials with an ordered porous structure that is difficult to make using traditional methods [121,338-348], Thus, CMK-3 carbon was first demonstrated as a template to prepare mesoporous silica [121,338]. An OMC prepared from an MCM-48 template was used to prepare nanostructured silica [339]. Nanocasting of CMK-3 using ZSM-5 crystals yielded a mesoporous zeolite with both mesopores and micropores [340]. More recently, the preparation of a novel class of mesoporous aluminosilicate molecular sieves was described [341]. The preparation of mesoporous boron nitride (MBN) and mesoporous carbon nitride (MBCN) with very high surface area and pore volume was recently realized using a well-ordered hexagonal mesoporous carbon as a template and boron trioxide as a boron source [342]. Nonspherical silica nanocases with a hollow core and mesoporous shell were also produced [343]. [Pg.116]

Semiconducting one-dimensional (ID) nanolibers or nanowires are of interest for a wide variety of applications including interconnects, functional devices, and molecular sensors as well as for fundamental physics studies. Devices have been fabricated fi om semiconductor, and carbon nanotubes, and more recently from ICP nanofibers. It has been predicted that ICP nanofibers will have unique electrical, optical, and magnetic properties [134]. Several different methods for producing these ICP nanofibers have been developed with or without the aid of a template. The template-based methods involve synthesizing a tubular structure of the ICP within the pores of a support membrane, such as an alumina membrane [135] or a track-etched polycarbonate membrane [136]. However, more recent work has... [Pg.1175]
