“…Microporous materials, such as activated carbons (ACs) [15,16,17,18,19], zeolites, silicas, porous organic-inorganic hybrid frameworks [20,21,22], and porous organic polymer networks [23,24,25], are excellent candidates for these applications. Among the porous organic systems, the Porous Aromatic Framework (PAF) family has received great attention recently [26,27,28], thanks to their exceptional stability and their very high surface area; in particular, PAF-302 (also called PAF-1 in the literature) exhibits one of the highest BET surface areas reported so far, along with a high affinity for methane [29,30,31], and to a certain extent, for CO 2 [32,33,34,35,36].…”
