A fast response & recovery H2S gas sensor based on α-Fe2O3 nanoparticles with ppb level detection limit.
TL;DR: H2S gas sensor based on α-Fe2O3 nanoparticles was fabricated by post-thermal annealing of Fe3O4 precursor which was synthesized using a facile hydrothermal route and exhibited the best sensitivity, reproducibility and long-term stability.
Journal ArticleDOI
Ultra-highly sensitive and selective H2S gas sensor based on CuO with sub-ppb detection limit
TL;DR: In this paper, a gas sensor based on CuO has been fabricated to detect an ultra-trace H2S gas, which achieved a ppb level detection limit and showed outstanding selectivity and high sensitivity.

TL;DR: In this article, the gas-sensing properties of the sensor based on porous α-Fe2O3 nanoparticles were investigated, and the result showed that the sensor exhibited a high performance in hydrogen sulfide (H2S) detection at room temperature.
Journal ArticleDOI
Surface acoustic wave ammonia sensor based on ZnO/SiO2 composite film
Shuangyue Wang,Ma Jinyi,Zhijie Li,Haiqiao Su,Nooraldeen Alkurd,Weilie Zhou,Lu Wang,Du Bo,Yongliang Tang,Dongyi Ao,Shouchao Zhang,Q.K. Yu,Xiaotao Zu +12 more
TL;DR: A surface acoustic wave resonator with ZnO/SiO2 (ZS) composite film used as an ammonia sensor has good selectivity, reversibility and stability at room temperature and can be attributed to the enhanced absorption of ammonia and unique surface reaction on composite films due to the existence of silica.
