| 英文摘要 | Noble metal modification was a very promising way to enhance the gas-sensing properties of semiconductor materials. Therefore, gas sensors based on noble metal modified semiconductor materials had received much attention. In this work, PdO-modified alpha-Fe2O3 (denoted as PdO-alpha-Fe2O3) composite nanocrystals were fabricated by simple hydrothermal approach and wet impregnation means. The outcome disclosed that the 1.0 wt% PdO-alpha-Fe2O3 sensor exhibited better response in detecting dimethyl disulfide (DMDS) than that of pure alpha-Fe2O3 sensor and other PdO-alpha-Fe2O3 sensors based on different content of palladium oxide. Specially, the maximum response value in testing 100 ppm DMDS for 1.0 wt% PdO-alpha-Fe2O3 sensor can reach 113.1, and that of original alpha-Fe2O3 sensor was 11.1. Moreover, the outstanding selectivity, fast response recovery time (1 s/68 s), superior repeatability and stable long-term stability toward 100 ppm DMDS distinguished this 1.0 wt% PdO-alpha-Fe2O3 sensor from pristine alpha-Fe2O3 sensor. Here, the function and sensing mechanism of 1.0 wt% PdO-alpha-Fe2O3 were also discussed. (C) 2020 Elsevier B.V. All rights reserved. |
