A new sensing material design based on chemically passivated phosphorene/porous two-dimensional polymer: Highly sensitive and selective detection of NO2

[Display omitted] •A new gas sensing material was designed based on CPP/T-2DP.•Sensitivity of CPP/T-2DP improved by over 5-fold compared with phosphorene.•An enhancement mechanism was proposed for the highly sensitive NO2 detection.•The nanospacer intercalation strategy can be extended to other 2D s...
