Abstract
This application discloses a sheet-like Bi4Ti3O3 material related to the field of pressure catalysis technology. 12 / Bi 12 TiO 20 The present invention relates to a method for preparing and applying piezoelectric catalytic materials. Bismuth nitrate pentahydrate is used as the Bi source, tetrabutyl titanate is used as the titanium source, and the pH is adjusted with sodium hydroxide. After stirring until homogeneous, a hydrothermal reaction is carried out to obtain Bi₄Ti₃O₃. 12 / Bi 12 TiO 20 Piezoelectric catalyst. This invention synthesizes Bi₄Ti₃O₃. 12 / Bi 12 TiO 20 The piezoelectric catalyst method is simple, low-cost, and requires simple and easy-to-operate equipment. The catalyst prepared in this invention, compared to Bi₄Ti₃O₃ alone... 12 Or Bi 12 TiO 20 Piezoelectric catalysts exhibit superior performance in piezoelectric catalytic water splitting for hydrogen production.
