| titleOfInvention | alpha-Fe2O3/Bi2WO6Shell composite photocatalyst and preparation method thereof |
| abstract | The invention relates to the field of photocatalysts, and provides alpha-Fe for solving the problems of low efficiency, high preparation cost and the like of the existing photocatalyst in use 2 O 3 /Bi 2 WO 6 Shell composite photocatalyst and a preparation method thereof. The composite photocatalyst takes shell powder as a carrier, and the carrier is connected with nano Bi 2 WO 6 And nano alpha-Fe grows in situ on the carrier 2 O 3 And alpha-Fe thereof 2 O 3 And Bi 2 WO 6 The content of (A) is 2.5-3.5 wt% and 23-27.5 wt%, respectively. The preparation method comprises the following steps: 1) the method comprises the following steps of (1) taking shell powder as a carrier, and dispersing the carrier in a dispersing agent; 2) adding bismuth tungstate and an iron source into a dispersing agent, uniformly mixing and then curing to obtain a precursor; 3) firing the precursor to obtain alpha-Fe 2 O 3 /Bi 2 WO 6 Shell composite photocatalyst. The method has the advantages of wide raw material source, low cost, simple process, easy operation and suitability for large-scale production. |
