Monoclinic bismuth vanadate (m-BiVO4) with novel hollow peanut-like morphology was synthesized for the first time using l-lysine as surfactant. The use of l-lysine and the crystallization procedure is indispensable in getting the peanut-like morphology. The photocatalytic activity of the m-BiVO4 samples under solar-light irradiation was evaluated for degradation of crystal violet and methylene blue. Crystallization and calcination temperature are important factors affecting the photocatalytic activity of m-BiVO4, and best performance was observed over the sample that crystallized at 160 °C in the presence of l-lysine and subsequently subjected to calcination at 550 °C. The as-prepared BiVO 4 showed good stability in catalyst recycling. Based on the results of XRD, XPS, FESEM, TEM (HRTEM), UV-vis diffuse reflectance spectroscopy, and N2 adsorption-desorption characterization, the good photocatalytic activity of the m-BiVO4 sample is attributed to its unique hollow peanut-like morphology and pure monoclinic phase of high crystallinity.
