A min review of bismuth molybdate based photocatalysts for pollutant degradation

The sustainable development of the environment and human health are significantly impacted by a variety of pollution problems. Semiconductor photocatalytic technology has demonstrated exceptional potential in the area of pollution degradation. Bismuth molybdate (Bi₂MoO₆) has shown great potential in photocatalytic degradation, due to its stable characteristics and adaptable band structure. However, Bi₂MoO₆ exhibits less than ideal photocatalytic performance, attributed to its critical scientific issues, such as poor charge separation ability and limited catalytic active sites. Therefore, much researches have been carried out extensively on the modification of Bi₂MoO₆. This review summarizes Bi₂MoO₆ from three aspects, including the structure and synthesis method, four highly favored strategies of modification of Bi₂MoO₆, applications of Bi₂MoO₆ in photocatalytic degradation. In addition, potential and challenges of Bi₂MoO₆ are proposed.
