Flame Spray Pyrolysis (FSP) was performed for the synthesis of high specific surface area (SSA_(bet)) of SnO_2 nanopowders (141.6 m~3/g) and supported palladium (Pd) nanoparticles containing 0.2-3 wt%Pd with controlled size and a crystallinity in a single step. The particles properties were further characterized by XRD, BET and TEM analyses. The crystalline particles were used for sensing film preparation by spin coating. It was found that the flame-spray-made 0.2 wt%Pd/SnO_2 sensor showed higher and faster response to reducing H_2 gas than pure flame-spray-made SnO_2 sensor.
