BiVO 4 with dominant monoclinic structure and relatively high surface area has been prepared by a simple precipitation method. Smaller particle size and new morphologies were observed while using non‐toxic and common organic additives including ethylene diamine tetra acetic acid (EDTA) as the synthesis constituents. The prepared materials were characterized using structural, textural and microscopic techniques. The photocatalytic activities of the samples were checked using methylene blue, phenol and 2,4,6‐trichlorophenol as probe molecules and visible light as irradiation source. Also, hydrothermally‐ synthesized counterparts of the catalysts were prepared and their structure and photocatalytic efficiency were compared. The recovery of the catalysts after successive uses was also examined.
