“…Monoclinic BiVO 4 has been considered as a very promising photocatalyst due to its small band gap energy (2.45 eV) and excellent visible-light photocatalytic activity. , Nevertheless, the rapid recombination of photogenerated charge pairs and poor electrical conductivity of BiVO 4 limit its wide application in photodecomposition of organic pollutant and photocatalytic evolution of O 2 . To overcome the aforementioned limitation, various strategies have been developed, which include morphological control, loading cocatalyst, impurity doping, and heterojunction construction. − Among them, coupling BiVO 4 with metal or other matched semiconductor into composites has been regarded as a very effective approach, and various composites based on BiVO 4 have been fabricated, such as BiVO 4 /Bi 2 S 3 , BiVO 4 /BiOCl, BiVO 4 /Ag, BiVO 4 /Bi 2 O 3 , BiVO 4 /AgI, BiVO 4 /WO 3 , and BiVO 4 /Ag/Ag 3 PO 4 . − The enhancement of photocatalytic activity of these composites is mainly ascribed to the improved visible-light adsorption and reduced recombination rate of photoinduced electron–hole pairs. However, as far as we know, there are few reports on coupling BiVO 4 with Bi to construct composite photocatalyst and its photocatalytic activity. , …”
