Next, the generation of reactive species in the Co@VMT MEM/PMS system was detected by EPR. 5,5-Dimethyl-1-pyrroline (DMPO) can capture•OH and SO4•–species. Signals corresponding to both DMPO–•OH adducts (hyperfine coupling constants AN = AH = 14.9 G) and DMPO–SO4...
to push the external air through the device (Fig.1a). An electric heater was placed next to the fan such that during the desorption phase of a given cycle, heated air can provide the necessary energy to release the adsorbed water from the MOF pores and carry that desorbed water vapor at...
