Abstract The mixed semiconductor metal oxides as the gas sensor can enhance the sensitivity compared with the metal oxide respectively. In this study, the mesoporous ZnO@Co3O4 nanosphere was prepared through the simple hydrothermal synthesis method of ZIF-L-Zn@Co, the cage construction of mesoporous ZnO@Co3O4 nanosphere was remained unchanged after the calcination of the ZIF-L-Zn@Co at 600℃ for 2 h in the air. The mesoporous ZnO@Co3O4 nanosphere was selected as the gas sensor for the detection of 3-Hydroxy-2-Butanone. Compared with the ZnO and Co3O4 respectively, the mesoporous ZnO@Co3O4 nanosphere as the gas sensor shows the high sensitivity, selectivity and stability.

Mesoporous Zno

Porous ZnO microtubes have been synthesized via a facile hydrothermal method based on nanoparticle splicing growth and the preferential etching strategy in the hydrothermal reaction system with high supersaturation. The ZnO tubes have hexangular wurtzite structure with a dimension of about 6 to 12 m in length, 4 m in diameter and about 40 nm in wall thickness, which is made of numerous mesopores with diameter ranging from 40 nm to 200 nm.
