CS2 adsorption isotherms and cycling. a CS2 adsorption isotherms for mm-2–Mg2(dobpdc) at various temperatures. Adsorption capacity is in units of mmol g–1. b Comparison of individual adsorption isotherms of various gases at 75 °C collected for mm-2–Mg2(dobpdc) with pressure plotted on a logarithmic scale and adsorption capacity in units of mmol g–1. c CS2 adsorption isotherms collected for mm-2–M2(dobpdc) (M = Mg, Mn, Zn) at 25 °C with pressure plotted on a logarithmic scale. Adsorption capacity is in units of mol mol–1. Filled circles correspond to adsorption and open circles to desorption. d Ten temperature-swing adsorption–desorption cycles for mm-2–Mg2(dobpdc) under 75 mbar of CS2. Adsorption occurred at 35 °C (blue circles), and desorption occurred at 100 °C (red circles). Temperature was equilibrated for 30 min between measurements. White and gray columns illustrate successive adsorption–desorption cycles
