Resumen:
Tin dioxide in the form of thin lms has increasingattention for producing gas sensor. Their advantagesare good sensitivity and a low power consumption. Ithas been reported a single square shaped SnO2 nanotubeto ethanol [1]. Several advantages like higher activesurface area, exibility in surface modi cation forchemically or biologically selective catalysis, acceleratedtransport of gas/liquid and drastically enhancedelectrical transport properties have been reported.A SnO2 nanotube sheet sensor has also beencharacterized [2]. SnO2 nanotubes have been synthesizedusing a polycarbonate template method [3-5].The material was characterized by X-ray di ractionanalysis and scanning electron microscopy. Theelectrical measurements show that these lms have ahigher sensitivity respect to the conventional SnO2sensors.
