a, Activation process for PWPN-1 crystals. b, CO2 adsorption isotherm of PWPN-1a at 195 K. c, H2O and D2O vapour sorption curves at 298 K for PWPN-1a at P/Ps from 0 to 0.9. The exposure time for each point is 600 s. d, Time-dependent H2O and D2O adsorption curves at 298 K for PWPN-1a at P/Ps = 0.9. e, Determination of diffusion rates of H2O and D2O in PWPN-1a at 298 K. Here Sqrt time represents the square root of time. The adsorption pressure was set to P/Ps = 0.95. f,g, Experimental breakthrough curves of PWPN-1a for D2O/H2O mixture separation at 298 K and 1 bar: 80/20 (f) and 90/10 (g) volume ratio in the liquid (v/v). h, Comparison of breakthrough times for D2O/H2O mixtures at volume ratios of 80/20 and 90/10 at 298 K. i, Five breakthrough curves of the D2O/H2O mixture at a volume ratio of 90/10 at 298 K. j, Comparison of D2O vapour uptake of PWPN-1a over ten cycles at 298 K for a D2O/H2O mixture (90/10, v/v). k, Powder X-ray diffraction patterns of PWPN-1a before and after ten breakthrough cycling experiments.
