Effect of platinum impregnation on ZnO tetrapods for ethanol sensor

Platinum impregnated ZnO tetrapods were prepared and studied for the detection of ethanol vapor. ZnO tetrapods were synthesized by oxidation reaction technique by heating a mixer of zinc powder (99.99%) and hydrogen peroxide solution (30 wt.%) at 1, 000°C in air. Platinum was impregnated by dropping...
