The sample was activated at 150 oC for 12h
with dynamic vacuum before each measurement.The activated
sample weight was measured after experiment and was
used to calculate the SO2 adsorption results.The activated
sample weight for Ni(bdc)(ted)0.5,Zn(bdc)(ted)0.5 and Mg-
MOF-74 are 75.5 mg,94.2 mg and 95.6 mg respectively.The
activated sample was sealed in chamber B under vacuum.SO2(the total impurity of SO2 gas is less than 0.1% and the water
concentration is less than 0.01%) was introduced into chamber
A and then the valve connecting chamber A and B was opened
to let the gas adsorption reach equilibrium.This step was
repeated as necessary to obtain the adsorption data points.As
for the desorption part,a similar but reverse procedure was
adopted.The chamber A was evacuated (1×10 -4 Torr) and
then the valve connecting chamber A and B was opened to let
the gas desorption reach equilibrium.This step was also repeated
as necessary to obtain all desorption data points.
