文摘
- •
Mesoporous Co3O4 nanosheets were synthesized without using of surfactant or template.
- •
Mesoporous Co3O4 nanosheets based gas sensor shows a high response towards VOCs.
- •
Sensor has good repeatability, stability, fast response and recovery towards VOCs.
- •
Mesoporous structure increases surface area and oxygen specie to promote oxidation of VOCs.
