Highly porous tungsten-oxide-based films obtained by spray-gel for gas sensing applications
Descripción del Articulo
Highly porous mixed WO3–SnO2 films have been prepared from an aqueous solution of SnCl4.5H2O and polytungsten gel with a molar ratio of Sn/W from 0 to 1. These solutions were sprayed on to alumina substrates at 220 ºC. The obtained films were annealing at 600 ºC in air for 3 h. The annealed films we...
