Preparation of Magnetic Mesoporous TiO Photocatalysts Using Ferrocene Surfactants

Abstract

The invention discloses a method for preparing magnetic mesoporous titanium oxide photocatalytic material using ferrocene surfactant. The steps are: (1) equal amounts of N,N-dimethylferrocenylmethylamine and bromodecanoate. Hexane reaction; (2) Recrystallize from acetone, centrifuge, and vacuum dry at room temperature to obtain light yellow crystals, which are defined as ferrocene surfactant I with the hydrophilic end at the center of the molecular chain and the lipophilic end at both ends of the molecular chain; (3 ) Use bromoundecanoate to prepare ferrocene surfactant II with hydrophilic and lipophilic ends at both ends of the molecular chain through multi-step reaction, separation and purification; (4) Ferrocene surfactant is dissolved in ethanol solution; (5) Add KCl solution; (6) Add organic titanium; (7) Stir at room temperature, hydrothermal reaction; (8) Filter, wash, dry at room temperature, and calcine; (9) The powder sample is magnetic mesoporous titanium oxide. Photocatalytic materials. The preparation of magnetic mesoporous titanium oxide photocatalytic materials has high photocatalytic performance and a simple process.

Description

technical field [0001] The invention relates to a catalytic material, in particular to a magnetic mesoporous titanium oxide photocatalytic material prepared with a ferrocene surfactant. Background technique [0002] There are two main methods for the preparation of magnetic mesoporous titanium oxide photocatalytic materials: first, surface loading, and second, threshold-limited growth. Surface loading is the most traditional method for preparing mesoporous titanium oxide photocatalytic materials; among them, the preparation of titanium oxide-containing mesoporous photocatalytic materials by inorganic salt loading has been studied comprehensively, and these preparation methods make the active sites dispersed unevenly, resulting in its The catalytic activity is limited to some extent. Organic iron was used as a surfactant in the threshold-limited growth, and Tao Shengyang of Dalian University of Technology used pyridine-containing ferrocene lipids to prepare uniformly dispers...
