| 摘要 |
The present invention provides a method of killing and/or inactivating microbes, the method comprising the step of placing the microbes in contact with a catalyst by means of a fluid medium, wherein the catalyst comprises a solid support, which solid support comprises one or more fibres, and a first metal cation fixed to the support. The fibres are keratinous fibres like wool fibres, or polyacrylonitrile (PAN) fibres. The first metal cation is selected from transition metal copper, silver and gold included. A second non-transition metal cation can be present. The catalyst is prepared by first treating the fibres with hydrazine and/or hydroxylamine salt in presence of a base, the modified fibres are then treated with an aqueous solution of containing the metal cations.
