The present invention relates to a kind of BiOI (100)/BiOI (001) with phase homojunction and preparation method.Steps are as follows for preparation method of the present invention: first with Bi (NO 3 ) 3 •5H 2 O and KI, BiOI (100) basis material is prepared under hydrothermal conditions, obtained BiOI (100) basis material is mixed with the bismuth oxide powder of preparation, under hydrochloric acid effect bismuth oxide powder is converted to BiOI (001) in situ, and forms BiOI (100)/BiOI (001) with phase homojunction with BiOI (100).The advantages that present invention has preparation process novel, and operating process is simple, and low production cost, reaction condition is mild, is easy to large-scale production. |
