Hydrogen peroxide modified and bismuth vanadate decorated titanium dioxide nanocomposite (BiVO₄@HMT) for enhanced visible light photocatalytic growth inhibition of harmful cyanobacteria in water.

ABSTRACT: The persistence of harmful cyanobacterial algal blooms in aquatic ecosystems leads to health damage for various life forms. In this study, a photocatalyst active in the visible light range was prepared by combining BiVO₄ with hydrogen peroxide modified titanium dioxide (BiVO₄@HMT; for short), using an impregnation method. The catalyst was used to photocatalytically inhibit the growth of cyanobacteria collected from a bloom site. To infer the optimum pH for cyanobacterial growth, the effect of pH was studied. The growth of cyanobacteria was favoured in an alkaline environment at pH values in the range of 8-9.5 when analysed on the 20^th day of incubation. Structural and chemical analysis of pristine and composite nano-powders was performed using XRD, SEM, TEM
