| titleOfInvention | A kind of heterojunction type tri compound semiconductor light-catalyst and preparation method thereof |
| abstract | The invention discloses a kind of heterojunction type tri compound semiconductor light-catalyst and preparation method thereof.The present invention uses constant pH coprecipitation to prepare ternary layered double-metal hydroxide as presoma, most obtains ternary heterojunction composite semiconductor through high-temperature roasting afterwards.Preparation technology of the present invention is easy, resulting materials have appropriate band structure, carrier separation and migration rate can be effectively improved, efficiently utilize visible ray, serial ternary heterojunction composite semiconductor is prepared by the relative amount of selective regulation metal ion, high-activity photocatalyst is filtered out, shows good dyestuff degradation capability under visible light.Ternary heterojunction composite semiconductor has higher catalytic activity to 1.6 4.1 times that the visible light photocatalytic degradation reaction rate constant of methylene blue is binary composite semiconductor, has good universality in terms of dyestuff degraded under visible light. |
