Preparation and Regulation of a Platinum Nanoparticle Embedded Titanium Dioxide Material

ABSTRACT The development of a simple method to prepare platinum (Pt) nanoparticles embedded in titanium dioxide (TiO 2 ) is of great significance in catalytic. However, achieving uniform embedding of Pt nanoparticles into TiO 2 remains a challenge. In this paper, we developed a kind of platinum titanium metal organic frameworks as precursor material, and realized the in‐situ embedding of Pt nanoparticles in TiO 2 by simple heat treatment. By adjusting the heat treatment temperature and the content of Pt salt, the microstructure control of Pt embedded TiO 2 is realized, and the optimal Pt embedded in TiO 2 is obtained. The structure and morphology indicate that the Pt embedded in TiO 2 is a tablet like morphology and has oxygen vacancies. This work realized the in‐situ preparation of Pt embedded in TiO 2 , and optimized the experimental conditions to obtain the best structure and morphology of Pt embedded in TiO 2 , which is expected to be used in photoelectric catalysis.
