Monoclinic　BiVO4　with　multiple　morphologies　were　fabricated　using　the　alcoho-hydrothermal　strategy　with　bismuth　nitrate　and　ammonium　metavanadate　as　inorganic　sources,　NaOH　for　pH　adjustment,　and　the　triblock　copolymer　P123　as　a　surfactant.　The　materials　were　characterized　by　X-ray　diffraction,　nitrogen　adsorption-desorption,　scanning　electron　microscopy,　X-ray　photoelectron　spectroscopy,　and　ultraviolet-visible　diffuse　reflectance　spectroscopy.　The　photocatalytic　performance　of　the　BiVO4　samples　was　evaluated　for　the　degradation　of　methyl　orange　(MO)　under　visible-light　irradiation　condition.　The　results　showed　that　the　surfactant　and　pH　had　a　significant　influence　on　the　particle　morphology　of　the　BiVO4　product.　Porous　spherical,　flower-like,　and　sheet-like　BiVO4　were　fabricated　at　an　alcoho-hydrothermal　temperature　of　180　degrees　C　and　at　a　pH　of　2,　7,　or　10,　respectively,　whereas　rod-like　BiVO4　was　obtained　in　the　presence　of　P123　at　an　alcoho-hydrothermal　temperature　of　180　degrees　C　and　at　a　pH　of　2.　The　difference　in　BiVO4　particle　morphology　led　to　differences　in　surface　area,　surface　oxygen　vacancy　density,　and　(040)　crystal　plane　exposure.　Among　the　four　BiVO4　samples,　the　rod-like　sample　had　the　highest　surface　area,　surface　oxygen　vacancy　density,　and　(040)　crystal　plane　exposure,　and　the　lowest　bandgap　energy　resulting　in　it　having　the　best　photocatalytic　activity　for　MO　photodegradation.　It　can　be　concluded　that　a　morphological　effect　is　responsible　for　the　photocatalytic　performance　and　the　rod-like　morphology　seems　to　favor　an　enhancement　in　the　photocatalytic　performance　of　the　BiVO4　material.
