A low operating temperature and high performance sensor for H2S detection based on α-Fe2O3/TiO2 heterojunction nanoparticles composite
Firstly, a low operating temperature and high performance sensor for H 2 S detection based on α-Fe 2 O 3 /TiO 2 heterojunction nanoparticles (NPs) was developed by a liquid phase reaction with low synthesis temperature. Secondly, the microstructures and chemical compositions of the gas sensing mater...
