Abstract： Hydrogen sulfide （H2S） ， as a highly toxic pollutant， poses a serious threat to human health. It is important to develop an efficient H2S gas sensing platform from the perspective of environmental protection and human health. Herein， we fabricated MnO2/BN nanocomposites through high-temperature calcination method， which combined the advantage of the high catalytic property of MnO2 and high electron transfer efficiency BN， showing extraordinary cataluminescence （CTL） emission toward H2S . On the basis， a direct CTL sensing platform for H2S was established， which showed a broad linear range of 0.10-0.50μg/mL and low detection limit （0.03μg/mL） ， displayed a rapid， stable， selectively CTL response to H2S . The stability of the sensor was demonstrated to be remained well for at least 20 days.
