Abstract

Abstract: In this paper, the flower-like titanium dioxide microparticles (F-Ti MPs) were synthesized by a simple treatment of titanium dioxide nanoparticles (Ti NPs) in the NaOH solution via a hydrothermal method. Size and morphology of the resultant samples were characterized with a scanning electron microscopy (SEM) and a transmission electron microscopy (TEM). The results showed that F-Ti MPs had a hierarchical and flower-like morphology with the diameter around 3-5 μm and constructed by numerous nanowires. When incubated with the solution of methylene blue (MB, model organic pollutant), F-Ti MPs showed much stronger adsorption capacity to remove MB from water than Ti NPs.
