Methods for production of metal oxide nano particles, and nano particles and preparations produced thereby |
摘要 |
The invention provides a method for the formation of small-size metal oxide particles, comprising the steps of: a) preparing a starting aqueous solution comprising at least one of metallic ion and complexes thereof, at a concentration of at least 0.1% w/w of the metal component; b) preparing a modifying aqueous solution having a temperature greater than 50° C.; c) contacting the modifying aqueous solution with the starting aqueous solution in a continuous mode in a mixing chamber to form a-modified system; d) removing the modified system from the mixing chamber in a plug-flow mode; wherein the method is characterized in that: i) the residence time in the mixing chamber is less than about 5 minutes; and iii) there are formed particles or aggregates thereof, wherein the majority of the particles formed are between about 2 nm and about 500 nm in size. |
