Mechanochemical Synthesis of Bi(2)VO(5.5) for Improved Photocatalytic Dye Degradation

A single‐phase Bi(2)VO(5.5) powder is formed effectively through a mechanochemical ball milling approach at 650 °C in 5 h and its photocatalytic performance on methylene blue dye is explored. X‐ray diffraction and Raman spectroscopy analytical instruments are utilized to confirm the phase formation. The evident presence of irregular‐shaped grains is affirmed using a scanning electron microscope. To ascertain the chemical condition of the components present, the Bi(2)VO(5.5) powdered sample undergo an X‐Ray photoelectron spectroscopy investigation. The sample is analyzed using a time‐dependent photocurrent to discern its charge carrier transportation behavior. A photocatalytic study using Bi(2)VO(5.5) powder produced through the mechanochemical ball milling method has not been explored till now. The efficacy of the ball‐milled Bi(2)VO(5.5) powder to attain enhanced photocatalytic efficiency which hasn't been investigated till now, is explored. The ball‐milled Bi(2)VO(5.5) sample achieved 70% degradation efficiency when performing the photocatalysis investigation. The photocatalytic dye degradation discerns pseudo‐first‐order kinetics and achieves a notable k value of 0.00636 min(−1). The scavenger test indicates that h(+) radicals are the prominent active species during the photocatalysis experiment. The germination index is determined by conducting a phytotoxicity test with the use of Vigna radiata seeds. Here ball‐milled Bi(2)VO(5.5) powder attains enhanced dye degradation efficiency.
