The persistent challenge of poor recovery characteristics NO
Nitrogen dioxide (NO2), even at parts-per-billion (ppb) concentrations, can greatly threaten human health. Two-dimensional (2D) nonlayered metal oxides demonstrate the strong potential of detecting ppb-level NO2 gas low temperatures or room temperature with unique selectivity, owing to their physisorption behaviors molecules as well abundant active sites based on dangling bonds and defects.
