| titleOfInvention | Preparation method of piezoelectric/semiconductor heterojunction catalyst |
| abstract | The invention discloses a preparation method of a piezoelectric/semiconductor heterojunction catalyst, wherein the heterojunction catalyst is based on BiFeO 3 BiVO deposited on surface of piezoelectric micron powder 4 BiFeO composed of semiconductor nano-particles 3 /BiVO 4 A catalyst. The method comprises the following specific steps: firstly, synthesizing piezoelectric BFO particles with micron scale by using a hydrothermal method, then depositing semiconductor BVO nano particles on the surfaces of the piezoelectric BFO particles by using a coprecipitation method, and forming a stable BFO/BVO heterojunction after heat treatment. The heterojunction material has excellent synergistic catalytic activity, effectively combines piezoelectric catalytic activity and photocatalytic activity, and has catalytic decomposition efficiency of organic pollutants obviously higher than that under a single condition under the synergistic action of mechanical vibration and visible light irradiation. The invention skillfully designs the catalyst material, introduces the piezoelectric effect to improve the efficiency of heterojunction vibration/photocatalytic degradation, has wide application prospect in the field of wastewater treatment, has simple preparation process and can be applied to industrial production. |
