Studies from South China Normal University Yield New Data on Photocatalytics

May 13, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Photocatalytics have been presented. According to news originating from Guangdong, People's Republic of China, by NewsRx correspondents, research stated, "This study was conducted to synthesize a series of nanosized BiOI-TiO2 catalysts to photodegrade Bisphenol A solution. The BiOI-TiO2 nanoparticles were synthesized in the reverse microemulsions, consisting of cyclohexane, Triton X-100, n-hexanol, and aqueous salt solutions."

Our news journalists obtained a quote from the research from South China Normal University, "The synthesized particles were characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface analyzer, Fourier transform-infrared spectroscopy (FT-IR), ultraviolet-visible light (UV-Vis) absorption spectra and transmission electron microscope (TEM). The photodegradation of Bisphenol A (BPA) in aqueous suspension under visible light irradiation was investigated to explore the feasibility of using the photocatalytic method to treat BPA wastewater. The effects of different molar ratios of BiOI to TiO2 on the photocatalytic activity were discussed. The experimental results revealed that the photocatalytic effect of the BiOI-TiO2 particles was superior to the commercial P25 TiO2. The BPA degradation could be approached by a pseudo-first-order rate expression."

According to the news editors, the research concluded: "The observed reaction rate constant (kobs) was related to nanoparticles dosage and initial solution pH."
