摘要：

Both pure and Mn(II)-doped ZnO hollow structures were synthesized by a solvothermal reaction, and their phase structures, morphologies and elemental composition were characterized. SEM and TEM observations show the pure ZnO and the Mn(II)-doped ZnO balls to possess similar hollow structure with a particle size of about 1.5m. Their sensing properties were investigated, and the composite containing 1 atom% of Mn(II) (1% Mn-ZnO) is found be display the highest selectivity for acetone. The detection limit is 100ppm acetone at 234 degrees C which is 4.6 times lower than that of the pure ZnO. In addition, the response time is shorter.ZnO and Mn-doped ZnO hollow balls were prepared by a hydrothermal method, and their gas-sensing propertieswere investigated. Zinc(II) oxide doped with1 atom% Mn(II) demonstrated an outstanding sensing behavior towards acetonevapors.
