Fig. 6. GG and HEWL substrates interact strongly with NU-1000 as shown by physisorption and adsorption experiments: (a) N2 isotherm of NU-1000 as synthesized (black), after reaction with 2 mM GG, 60 °C, pH 7.0, 24 h (red), and after reaction with 0.02 mM HEWL, 60 °C, pH 7.0, 24 h (blue). (b) Adsorption of GG on NU-1000 as a function of concentration of GG at pD 7.4, 5.4 and 3.4 (room temperature, 6 h). (c) Pore size distribution of NU-1000 as synthesized (black), after reaction with 2 mM GG, 60 °C, pH 7.0, 24 h (red), and after reaction with 0.02 mM HEWL, 60 °C, pH 7.0, 24 h (blue).
