- •
Sn addition effectively improves water tolerance of Co3O4 for CO oxidation.
- •
Sn addition suppresses water vapour adsorption on the catalyst surface.
- •
Thus improving the water tolerance of the catalysts evidently.
- •
Sn addition has a mild influence on the CO oxidation activity of Co3O4.
- •
Co0.90Sn0.10 is promising due to its reasonable activity and water resistance.
