Abstract
ZnO hollow sphere with porous shell has been prepared by co-precipitation method using Zn(NO3)2·6H2O and (CH2)6N4 as reactants, sodium citrate as surfactant. The BET surface area of as-prepared ZnO hollow sphere sample is 41.84 m2/g. The response of gas sensor made from the obtained ZnO hollow sphere reaches 7.4 to 10 ppm ammonia, with a response time of 10 s, implying the potential for practical applications.
