Effective Factors on Methane Sensing of Tin-Oxide Activated by Palladium in Sol-Gel Process

Effective Factors on Methane Sensing of Tin-Oxide Activated by Palladium in Sol-Gel Process

Stannic oxide thin films activated by palladium were prepared by sol-gel method. The morphology of the layers and the size of the particles were investigated by scanning electron microscopy and atomic force microscopy. Investigations showed that the number of coating, annealing procedure and the vis...
