“…Carbon–based systems of different dimensionality, such as single/multiwalled carbon nanotubes, graphene-like, activated carbons, and carbon-based aerogels have attracted an increasing attention in the past and at the time of writing this paper. Recent works have shown that all these nanocarbons have distinctive properties, including electrical conductivity, chemical inertness, sorption, sensing, and biosensing (Cravotto et al, 2011 ; Cesano et al, 2012b , 2016 ; Holzinger et al, 2014 ; Badhulika et al, 2015 ; Li et al, 2015 ; Niu et al, 2015 ; Kotal et al, 2016 ). In the majority of cases, such properties can be better exhibited if nanocarbons are confined in another phase (i.e., polymers) (Wu et al, 2012 ; Cesano et al, 2013 ; Cravanzola et al, 2013 ; Niu et al, 2015 ), or are combined with other systems to form heterostructures (Wang et al, 2010 ; Ong, 2017 ; Rho et al, 2017 ), hybrids (Badhulika et al, 2015 ; Wang et al, 2016 ), composites (Bai and Shen, 2012 ), or simply when they are decorating the surface of inorganic solids (Wu et al, 2012 ; Cravanzola et al, 2016 ).…”
