“…Mays proposed that range of nanopores was 0.1–100 nm (Mays, 2007). Pores smaller than 5 or 10 nm, however, have apparently strong interaction potential with adsorbed molecules and we thus define nanopores as smaller pores than 5 nm (Ohba et al., 2015). These materials have been widely used as adsorbents for various gasses and liquids (Chandra et al., 2012; D’Alessandro et al., 2010; Hornbostel et al., 2013; Marco-Lozar et al., 2012; Martín et al., 2011, 2010; Plaza et al., 2010; Samanta et al., 2012; Sevilla et al., 2012; Sevilla and Fuertes, 2012; Suzuki, 1994; Wang et al., 2011; Xia et al., 2011; Yoon et al., 2004; Zhao et al., 2012).…”
