| titleOfInvention | A kind of microwave synthesis method of lanthanum/titania nanocomposite photocatalyst |
| abstract | The invention discloses a microwave synthesis method of a La/TiO 2 nanocomposite photocatalyst, comprising the following steps: (1) dissolving a surfactant in water, adding phthalein sulfate and lanthanum nitrate, and dispersing evenly to obtain a mixed solution A; ( 2) urea is added to the mixed solution A, and the mixture is uniformly dispersed to obtain a mixed solution B; (3) the mixed solution B is heated and reacted under a microwave, and the reaction is completely cooled to obtain a mixed solution C; (4) the supernatant of the mixed solution C is obtained. The liquid is discarded and the lower layer liquid is retained, and then the precipitate is obtained by centrifugation and washing, and the precipitate is dried; (5) heat treatment to obtain it. The beneficial effects of the present invention are: (1) a single feed reaction is obtained, which is simple and fast; (2) the microwave synthesis reaction speed is fast and the energy efficiency is high; (3) the main raw material used is Ti(SO 4 ) 2 , which is cheap and easy to obtain; ( 4) The catalytic efficiency is improved by heat treatment; (5) The synthesized product has excellent photocatalytic performance; (6) The incorporation of lanthanum as a transition metal can improve the photocatalytic performance. |
