“…The turbostratic microstructure of these "non-graphitic" carbon materials combined with variable conductivity and a significant nanoscale disordered porosity are typical features of this kind of carbon materials. Templating strategies are meanwhile well established to endow carbon materials with defined porosity on the nanometer scale, in particular to enhance the surface area and to control the pore size [9][10][11][12]. This study is dedicated to a quantitative determination of the porosity, e.g., pore size, pore volume and pore shape of carbon materials prepared by hardtemplating of meso-macroporous SiO 2 monoliths, and to a linkage of these parameters to the corresponding nanoscale polyaromatic microstructure.…”

This study is dedicated to link the nanoscale pore space of carbon materials, prepared by hard-templating of meso-macroporous SiO 2 monoliths, to the corresponding nanoscale polyaromatic microstructure using two different carbon precursors wthat generally exhibit markedly different carbonization properties, i.e., a graphitizable pitch and a non-graphitizable resin. The micro-and mesoporosity of these monolithic carbon materials was studied by the sorption behavior of a relatively large organic molecule (p-xylene) in comparison to typical gas adsorbates (Ar). In addition, to obtain a detailed view on the nanopore space small-angle neutron scattering (SANS) combined with in situ physisorption was applied, using deuterated p-xylene (DPX) as a contrast-matching agent in the neutron scattering process. The impact of the carbon precursor on the structural order on an atomic scale in terms of size and disorder of the carbon microstructure, on the nanopore structure, and on the template process is analyzed by special evaluation approaches for SANS and wide-angle X-ray scattering (WAXS). The WAXS analysis shows that the pitch-based monolithic material exhibits a more ordered microstructure consisting of larger graphene stacks and similar graphene layer sizes compared to the monolithic resin. Another major finding is the discrepancy in the accessible micro/mesoporosity between Ar and deuterated p-xylene that found for the two different carbon precursors, pitch and resin, which can be regarded as representative carbon precursors in general. These differences essentially indicate that physisorption using probe gases such as Ar or N 2 can provide misleading parameters if to be used to appraise the accessibility of the nanoscale pore space.

“…The black solids with the ZSM-5 mesoporous template (ZMC) were dissolved in fluoride acid (HF) 48% at a room temperature in order to take out the anorganic/inorganic ZSM-5 template frames. The obtained ZMC carbon solids were filtered, washed with deionized water until the filtrate reached a neutral pH level and dried at a temperature of 90°C for 12 h [8,12].…”

“…Three classes of porous materials are defined according to their pore sizes, namely microporous (pore size <2 nm), mesoporous (2 nm < pore size <50 nm), and macroporous (pore size >50 nm) [1]. Porous carbon materials of designed porosities and tunable properties, with high surface area, tunable porosity and surface property, good electrical conductivity, high chemical stability, have attracted intense interests in separation science and water purification, stationary phase materials, heterogeneous catalyst supports, sensing devices, and energy generation and storage applications (fuel cells, batteries, solar cells, and supercapacitors) [2][3][4][5][6].…”

Article HistoryCarbon materials mostly involved in new alternative clean and sustainable energy technologies have been playing more and more significant role in energy storage and conversion systems, especially for the carbon porous materials, because carbon porous materials with structures can provide large surface areas for reaction, interfacial transport, or dispersion of active sites at different length scales of pores and shorten diffusion paths or reduce diffusion effect. Therefore, the soft, hard templated and hierarchically ordered strategies employed to fabricate porous carbon materials are marked along with the relevant advantages and disadvantages aim to provide the vital information about the growing field for future energy to minimize the potential environmental risks. Carbon porous materials with attractive structures as ideal candidates for the versatility and feasibility of application to energy storage and conversion should not only be realized, but also much effort has to be devoted to systematic studies on the relationship between physicochemical properties of these materials and their performances in energy conversion and storage to more efficiently stimulate further developments in this fascinating area, alongside eco-technologies that will ensure minimal environmental impact. Contribution/Originality:This study contributes in the existing literature of carbon porous materials with attractive structures ordered by various techniques for future eco energy.
