Embodiment Construction

[0009] An antibacterial agent palladium-doped nano-titanium dioxide is characterized in that the palladium-doped amount is 1 to 5 mol%, and the palladium-doped nano-titanium dioxide particle average particle size is 6-12nm; it is made of PdCl 2 The solution was prepared by adding dropwise to a solution of tetrabutyl titanate in isopropanol at 30°C.

[0010] Preferably, the doping amount of palladium is 3 mol%.

[0011] A preparation method of nano titanium dioxide doped with antibacterial agent palladium, characterized in that the steps are as follows:

[0012] (1) PdCl 2 Dissolve in double distilled water to obtain solution A;

[0013] (2) Add tetrabutyl titanate dropwise into isopropanol, stir at room temperature for 30 minutes, and adjust the pH value to 3-4 with acid to obtain solution B;

[0014] (3) At 30°C, use a constant pressure funnel to drop the solution A prepared in step (1) into the solution B prepared in step (2), stir at room temperature, and then age to obt...

Abstract

The invention relates to a palladium-doped nano titanium dioxide anti-bacterial agent and a preparation method and an application thereof, belonging to the technical field of antibacterial material. The preparation method comprises the following steps: dropwise adding PdCI2 solution to the mixed solution of tetrabutyl titanate and isopropanol; after ageing, washing and drying the mixture to gel; grinding the mixture before carrying out calcination, thus obtaining the palladium-doped nano titanium dioxide anti-bacterial agent. The invention features simple production technology, high product purity, small grain diameter, good thermal stability, strong antibiotic property and can catalyze part of palladium catalytic reaction.

Description

technical field [0001] The invention relates to a palladium-doped nano-titanium dioxide antibacterial agent and a preparation method and application thereof, belonging to the technical field of antibacterial materials. Background technique [0002] In recent years, due to the characteristics of good safety, high stability and strong antibacterial properties, inorganic nano-antibacterial agents have attracted widespread attention. So far, the most common inorganic nano-antibacterial agent is nano-titanium dioxide. According to literature reports, the antibacterial performance of nano-titanium dioxide is improved to a certain extent after doping with metal ions, such as silver, copper and zinc. For example, the Chinese patent with the publication number CN1775032 discloses a nano-titanium dioxide-supported metal ion antibacterial agent and a preparation method thereof. Nano-titanium dioxide is used as a carrier, and antibacterial metal ions are attached to the carrier, and th...
