Resumen

Density functional theory (DFT) calculations were undertaken to investigate the effect of Fe-doping on the capability of a graphene-like BC₃ nano-sheet (Fe@BC₃NS) in detecting the gas SO₃. The interaction of the pure BC₃NS with SO₃ was a physisorption, showing that it could not be used as a sensor. However, there was a considerable increase in the sensitivity and reactivity of the BC₃NS after Fe was replaced with B. The adsorption energy of SO₃ increased from 7.9 to 23.3 kcal/mol after doping Fe into the surface of the BC₃NS. Moreover, there was a reduction in the energy gap of Fe@BC₃NS (∼-38.9%) after SO₃ was adsorbed, which increased the electrical conductivity to a great extent. Therefore, we found that Fe-doping increased the sensitivity of the BC₃NS to SO₃ with a short recovery time of 9.5 s at room temperature. Our theoretical results further supported the fact that metal@BC₃ nano-structures have widespread practical applications.
