Sulfur-functionalized carbon aerogels: a new approach for loading high-surface-area electrode nanoarchitectures with precious metal catalysts

Improved carbon nanostructures as a novel catalyst support in the cathode side of PEMFC: a critical review

“…The same result for seven types of carbon aerogels (CAs) samples with different pore size distributions was reported by OuattaraBrigaudet et al [184]. Guilminot [185] [186][187][188]in separate works studied the positive effect of nitrogen and sulfur doping on CA through ORR, and Wohlgemuth [189], reported the positive effect of nitrogen and sulfur dual doped CA on electrocatalyst performance of ORR in acidic and basic environment and strongly suggested these materials as a promising candidate for future energy. More activity was observed in basic medium as it is typical for carbon nanostructures, and in acidic media dual doped carbon shows higher stability than Pt base catalyst, and other ordinary carbon supports.…”

Cobalt- and iron-containing nitrogen-doped carbon aerogels as non-precious metal catalysts for electrochemical reduction of oxygen

“…Also the favourable physical properties, such as high electrical conductivity, high surface area and suitable pore structure contribute to the performance of the catalyst [45]. For the fuel cells, optimising the structure of the noble metal catalysts is still actual and there are several studies of ORR on Pt nanoparticles supported on carbon aerogels [48][49][50][51][52]. However, most of the research efforts are nowadays directed to the development of NPMCs, where carbon aerogel-based catalysts have also displayed promising electrocatalytic properties.…”

A new process for desalination and electrodeionization of water by means of electrostatic shielding zones – ionic current sinks.

“…For this purpose extra thin ICSs are needed, so as not to exceed the electrochemical decomposition potential of water and to avoid the unproductive charge transfer reactions through faradaic currents I f at their polarized sides as illustrated in fig.1a.b,c. Such thin ICS sheets could be constructed by specific chemical vapour deposition on thin perforated metallic sheets [32,33], by the paste rolling method [51] or as described in [35,36].…”

“…New nanoporous carbon aerogel electrodes [28,[30][31][32], carbon nanotubes and nanofibers [33][34][35][36], or activated nanostructured carbon cloths [29,[37][38][39] have been recently developed with increased specific surface area which reduce the number of the electrode charge/discharge cycles and therefore improve significantly the desalting rate and the efficiency of the capacitive deionization process.…”
