BN/NiO nanocomposites: Structural, defect chemistry and electrical properties in hydrogen gas atmosphere

Highly sensitive work function type room temperature gas sensor based on Ti doped hBN monolayer for sensing CO2, CO, H2S, HF and NO. A DFT study

“…Therefore researchers have countered this problem and enhanced the gas sensing by surface activation through, 22,23 foreign element doping [24][25][26] and defect engineering. 27,28 It has been proved that metal decoration on 2D materials can significantly enhance the gas adsorption affinity of 2D materials. 29,30 Ramirez-de-Arellano et al have checked the CO interaction with hBN monolayer by six models; B-vacancy hBN, N-vacancy hBN, Ti doped in N-vacancy, Ti doped in B-vacancy, Pt doped in Nvacancy and Pt doped in B-vacancy.…”
