preparation example Construction

[0041] The invention discloses a method for preparing inorganic nano materials, which includes the following steps:

[0042] Step a1) mixing the acidic solution of the titanium source compound, naphtha, non-ionic emulsifier and alcohol compound, and forming an emulsion system after stirring;

[0043] Step a2) Add a solution of the source A compound to the emulsion system, adjust the pH value, and obtain an inorganic nanomaterial after the reaction. The source A compound is a strontium source compound and / or a barium source compound.

[0044] In the above preparation process, the present invention uses naphtha as a continuous phase and alcohol compounds as co-emulsifiers to form a nano-scale reverse micelle system, and uses the reverse micelle system as a microreactor. The source compound reacts with the A source compound to form an inorganic nanomaterial. Among them, the reverse micelle refers to a system in which aqueous droplets (dispersed phase) are dispersed in an oil phase (con...

Abstract

The invention provides an inorganic nano-material, an organic nano-material, a hybrid nano-material and a preparation method thereof. Naphtha is taken as a continuous phase and an alcohol compound is taken as a co-emulsifier, so that a nanometer-scale reversed micelle system is formed and the nanometer-scale reversed micelle system is taken as a micro-reactor; and the inorganic nano-material, the organic nano-material and the hybrid nano-material are respectively formed by a reversed micelle method. As naphtha, the non-ionic emulsifier and the alcohol compound are suitable for wider pH value range and reaction temperatures, the preparation method provided in the invention is easy to control; and the process for preparing the inorganic nano-material by the reversed micelle method is simple and suitable for industrial production.
