Unique Interaction between Layered Black Phosphorus and Nitrogen Dioxide.

ABSTRACT: Air pollution caused by acid gases (NO₂, SO₂) or greenhouse gases (CO₂) is an urgent environmental problem. Two-dimensional nanomaterials exhibit exciting application potential in air pollution control, among which layered black phosphorus (LBP) has superior performance and is environmentally friendly. However, the current interaction mechanism of LBP with hazardous gases is contradictory to experimental observations, largely impeding development of LBP-based air pollution control nanotechnologies. Here, interaction mechanisms between LBP and hazardous gases are unveiled based on density functional theory and experiments. Results show that NO₂ is different from other gases, as it can react with unsaturated defects of LBP, resulting in oxidation o
