英文摘要	The separation efficiency of photocarriers is an important part of photocatalytic efficiency. Construction of composite with good contact is a hot topic. In this work, Bi2WO6 is successfully connected with BiOI to form the chemical bonding interface through the same crystal unit, where a precipitation transformation phenomenon is revealed. The chemical bonding interface is conducive to transmission and separation of photocarriers to realize rapid and stable transport and separation through the interface, which is based on the photocurrent density of Bi2WO6/BiOI (BWOI) is about 6 and 40 times higher than Bi2WO6 and BiOI, and the transfer resistance of BWOI is around 5 and 10 times lower than Bi2WO6 and BiOI. Thus, the photocatalytic activity of BWOI is 2.8 and 33.35 times as much as those of Bi2WO6 and BiOI. During the photocatalysis process, photogenerated holes (h(+)) and superoxide radical (center dot O-2(-)) are the main oxidizers, and the constructed the chemical bonding interface displays excellent photostability.
