Abstract. In this paper, we have studied the interaction between two-dimensional sheet BC3 with carbon monoxide (CO), hydrogen sulfide (H2S) and sulfur dioxide (SO2) molecules. These molecules are part of a fire smoke and are extremely hazardous to human health. The aim of our study is to find out the possibility of creating a sensor device based on the BC3 sheet material, which is capable to registers the presence of the molecules in the air. Carbon monoxide, which is also carbon monoxide, is considered the most dangerous in the event of a fire. Carbon monoxide, compared to oxygen, can be more effectively adjacent to hemoglobin, which entails a deterioration in the ability of blood to absorb oxygen. In this regard, oxygen starvation occurs. Sulfurous gas (SO2) is colorless, but has a rather sharp smell and is formed if sulfur is contained in combustible or explosive substances. In addition, sulfurous gas is poisonous, and can form sulfuric acid on the surface of the eyes or airways if affected. It can cause swelling of the larynx and lungs, inflammation of the bronchi. A dangerous concentration for life is only 0.05% even with short-term breathing. Hydrogen sulfide (H2S), like sulfur dioxide, is colorless. However, it has a sweet taste and smell. It is able to be released during fires and during rotting of organic substances. Extremely poisonous gas, affects the eyes and airways. A deadly concentration even in the case of short-term breathing is only 0.1%.
Key words: two-dimensional layer, carbon monoxide, hydrogen sulfide, sulfur dioxide, sensor device, DFT, B3LYP.
