Unique Pd/PdO–In2O3 heterostructures for the highly efficient detection of triethylamine

Abstract

Triethylamine significantly harms the human body, so it is important to develop a triethylamine gas sensor with excellent performance for triethylamine detection. In this work, a Pd/PdO–In2O3 triethylamine gas sensor is developed by a simple, low-cost method, which exhibits improved comprehensive performance for triethylamine detection, including high sensitivity, fast response/recovery time, good selectivity, long-term stability, and certain moisture resistance. The unique method simultaneously realizes Pd loading and multiple PdO–In2O3 P–N heterojunctions, which accelerate the electron transport speed and increase electron transport channels, ultimately endowing Pd/PdO–In2O3 with excellent triethylamine sensing performance. This provides new methods and insights for preparing high-performance triethylamine sensors.
