AB  - The rational design of nanoscale metal oxides with hollow structures and tunable 
      porosity has stimulated tremendous attention due to their vital importance for 
      practical applications. Here, we report the designed synthesis of ZnO/ZnCo(2)O(4) 
      hollow core-shell nanocages (HCSNCs) through a metal-organic framework (MOF) 
      route. The strategy includes the synthesis of a zeolite imidazolate framework-8 
      (ZIF-8)/Co-Zn hydroxide core-shell nanostructure precursor and subsequent 
      transformation to ZnO/ZnCo(2)O(4) HCSNCs by thermal annealing of the as-prepared 
      precursor in air. Various techniques were employed for characterization of the 
      structure and morphology of the as-prepared ZnO/ZnCo(2)O(4) HCSNCs. When applied 
      as a gas sensing material, the ZnO/ZnCo(2)O(4) HCSNCs show enhanced sensitivity 
      to xylene when compared with ZnCo(2)O(4) shells as well as ZnO nanocages (NCs). 
      In addition, excellent reversibility and superior selectivity of the sensor were 
      observed. The remarkable enhancement in the gas-sensing properties of the 
      ZnO/ZnCo(2)O(4) HCSNCs is attributed to their unique structure and a synergistic 
      effect of ZnO and ZnCo(2)O(4).
