Ultra-sensitive SnO2 gas sensors based on hierarchical octahedra
Résumé
The controlled hydrolysis of Sn II precursor ([Sn(NMe) 2 ] 2 ) yields micrometric Sn 3 O 2 (OH) 2 octahedra, formed by a self-assembly process. The water content and alkylamine surfactants are major parameters for the growth process. These structures have been employed to prepare highly sensitive gas sensors, which present 7% variation of their resistance at only 0.25 ppm CO.
