Special Issue Information

Dear Colleagues,

One of the great technological challenges in the 21st century is the development of renewable materials designs due to the lack of source materials. A new promising area experiencing rapid research development is nanotechnologies, which is currently generating a lot of attention and therefore building great expectations not only in the academic community but also among investors, governments, and industries. This Special Issue will present a collection of the most recent advances in nanotechnology, including theoretical and experimental works related to renewable material production and their applications in energy, sensors, electrocatalysts, etc. The aim of the Special Issue is to introduce several significant contributions to nanotechnology in terms of materials designs from numerous research groups working on different aspects. We think that this paper can be considered as an important bridge between nanotechnology and all the available types of renewable materials design.

Experimental assessment of the hydrogen (H2)-adsorption capacities of metal-doped carbon nanostructured materials were investigated in this study. Given their intrinsic characteristics, nanostructured carbonic materials show great potential for different applications that require H2, one such being their use as hydrogen carriers in the automotive sector. The current paper considers two types of carbonic substrates (carbon nanotubes and polyaniline) functionalized and doped with platinic metals: Pt, Ru and Ir. The H2-adsorption capacities of the materials were assessed at 293 K and at relatively low pressures (10, 20 and 30 bar). Thus, nanostructured polyaniline (p-C6H5NH2) and multi-walled carbon nanotubes (MW-CNTs) were subject to noble-metal doping in order to assess their physical H2-adsorption capacities. The two types of substrates have different structures and characteristics, one being a “synthetic metal” and the other an amorphous carbon substrate. The metals used for doping were Platinum (Pt), Iridium (Ir) and Ruthenium (Ru), and the doping procedure consisted of chemical reaction between the metals’ salts and the carbonic substrate after the latter’s physical activation. Physical H2-adsorption capacity was determined with equipment designed to measure porous materials’ adsorption capacities at pressures ranging from 1 to 200 bar. The obtained results showed an increase inH2-adsorption capacity of 293% from 10 to 30 bar for Ru, 270% for Ir and 256% for Pt doping in the case of the MW-CNTs, and 296% for Ru, 282% for Ir and 251% for Pt from 10 to 30 bar in the case of p-C6H5NH2. As the main conclusion, even though Pt is known to be the main metal used in reactions involving H2, Ru and Ir showed better potential for this application, namely, as hydrogen-carrier materials for use in the automotive sector.
