POROUS NOBLE METAL OXIDE NANOPARTICLES, METHOD FOR PREPARING THE SAME AND THEIR USE |
摘要 |
The present invention discloses a method for preparing porous noble metal oxide nanoparticles, comprising the following steps: a) preparing an Olea Europaea fruit extract; b) preparing an Acacia Nilotica extract; c) mixing the Olea Europaea fruit extract and the Acacia Nilotica extract for preparing a mixed extract; d) providing an aqueous solution containing a noble metal compound dissolved therein; e) mixing the mixed extract obtained in step c) and the aqueous solution of step d); f) dropping a solution of sodium chloride to be mixture of step b); d) drying the mixture, in air or by vacuum, and h) calcining at a temperature between 100 to 900° C., to get the porous noble metal oxide nanoparticles; porous noble metal oxide nanoparticles obtained thereby and their use. |
