Abstract
In this paper, cobalt carbonate hydroxide (Co(CO3)0.5(OH)..11H2O) nanowires were successfully fabricated by a simple hydrothermal route without using surfactants and by subsequent heat treatment in air at 600â¯Â°C for 5â¯h to obtain mesoporous Co3O4 nanochains. As-synthesized nanochains with length of several micrometers consisted of well-linked Co3O4 nanoparticles with an average size of 50â¯nm. The sensor based on mesoporous Co3O4 nanochains was used to detect flammable and toxic gases, including H2S, NH3, CO, and H2. Results showed potential of mesoporous Co3O4 nanochains as sensor material for detection of hydrogen sulfides at low concentration with rapid response.
