  • Bismuth oxide/bismuth subcarbonate/bismuth molybdate composite photocatalyst and preparation method thereof
    Patent number: 11358125
    Abstract: The present invention discloses a bismuth oxide (Bi2O3)/bismuth subcarbonate ((BiO)2CO3)/bismuth molybdate (Bi2MoO6) composite photocatalyst, including a Bi2MoO6 photocatalyst, where Bi2O3 and (BiO)2CO3 nanosheets are introduced to a surface of the Bi2MoO6 through addition of Na2CO3 and roasting. The present invention also discloses a preparation method of the Bi2O3/(BiO)2CO3/Bi2MoO6 composite photocatalyst which is specifically implemented by the following steps: step 1: preparing a Bi2MoO6 photocatalyst; step 2: introducing Bi2O3 and (BiO)2CO3 nanosheets to a surface of the Bi2MoO6 photocatalyst obtained in step 1 through addition of Na2CO3 and roasting to obtain the Bi2O3/(BiO)2CO3/Bi2MoO6 composite photocatalyst. The photocatalyst of the present invention has no agglomeration, a wide responsive range of visible light, a significantly improved catalytic activity compared with a Bi2MoO6 alone, and excellent reusability.
