Abstract
-
In the present work, with the aid of the density functional theory (DFT) method, we have investigated the possibility of applying the B3S monolayer (B3SML) for sensing and adsorption of some air pollutants containing SO2, CS2, CO2, CH2O, H2O, C2H2, and CF3H from the gaseous environment. The results showed that after the adsorption of SO2, H2O, and C2H2 by B3SML, big changes took place which led to a decrease of the λmax of each complex down to 1598.5 nm, 1418.0 nm, and 1580.0 nm, respectively. Therefore, the frequencies of the mentioned adsorption complexes rise and strong blueshifts occur. Moreover, the outcomes of the band gap estimations reveal that the B3SML could selectively detect the existence of C2H2 with a clearer and stronger electronic signal compared to all other gases. In addition, this nanosheet is able to sense CS2, CH2O, SO2, and H2O with good signals. Hence, it could not recognize the difference between CH2O and SO2 gases. Also, the results of the thermodynamic calculations indicate that B3SML would selectively adsorb and destruct SO2, C2H2, and H2O gases. Moreover, this sorbent could adsorb CH2O and CS2 species, but it would approximately not adsorb CO2 and CF3H.
