Adsorption energy on rGO and WS2 of O2, NO2 and H2O molecules. Note that negative adsorption energy means that the adsorption process is exothermic and energetically favorable.

Physisorbed Molecules Adsorption Energy on rGO (eV) Reference Adsorption Energy on WS2 (eV) Reference
O2 −0.16 [36] −0.24 [36]
NO2 −0.80 [32,34,35] −0.41 [34,35]
H2O −0.04 [37] −0.23 [34]
