“…Moreover, in oxidations, when (atmospheric) oxygen is employed to regenerate carbocatalyst's active sites, water and/or hydrogen peroxide is the only by-products generated. 6,7 Alongside ACs, [3][4][5][6][7][8][9][10][11][12] other carbon allotropes such as carbon nanotubes (CNTs), [11][12][13][14][15] nanodiamonds (NDs), graphene oxides (GOs), [16][17][18] and nanohorns, have been employed as catalysts (Scheme 1) for organic transformations. 19,20 Gas-phase dehydrogenations of hydrocarbons in particular have been extensively studied with these materials, with received yields comparable to those of AC.…”
