文摘
- •
3D mesoporous Co3O4-k and 2D mesoporous Co3O4-s were synthesised by nanocasting method.
- •
Co3O4-k sensor exhibits more rapid and higher response to ethanol compared to Co3O4-s.
- •
These properties are due to high utilisation and accelerating gas diffusion in Co3O4-k.
- •
Charge transfer and adsorption energy of ethanol to Co3O4 is revealed by first-principles calculations.
