“…In recent years, monoclinic BiVO 4 (m-BiVO 4 ) has attracted considerable interest due to its narrow band gap compared with TiO 2 [2] and higher photocatalytic activity during the degradation of organic pollutant. Currently, various shapes of BiVO 4 have been prepared, such as sheets, tubes and spheres [3][4][5], but the high electronpairs recombination rate limits its application in the field of photocatalysis. Recently, the crystal facets exposed BiVO 4 was found that electrons and holes can be separated among the different crystal facets [6].…”
