Study Findings from Al-Azhar University Provide New Insights into Photocatalytics

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Photocatalytics are presented in a new report. According to news reporting originating in Cairo, Egypt, by NewsRx journalists, research stated, "Evaluation the photocatalytic activity of different Ln(3+) modified TiO2 nanomaterials using fluorescence based technique has rarely been reported. In the present work, x mol Ln(3+) modified TiO2 nanomaterials (Ln = Nd3+, Sm3+, Eu3+, Gd3+, Dy3+ and Er3+ ions; x = 0.005, 0.008, 0.01, 0.02 and 0.03) were synthesized by sol-gel method and characterized using different advanced techniques."

The news reporters obtained a quote from the research from Al-Azhar University, "The photocatalytic efficiency of the modified TiO2 expressed in the charge carrier separation and (OH)-O-center dot radicals formation were assigned using TiO2 fluorescence quenching and fluorescence probe methods, respectively. The obtained fluorescence measurements confirm that doping treatment significantly decreases the electron-hole recombination probability in the obtained Ln(3+)/TiO2. Moreover, the rate of (OH)-O-center dot radicals formation is increased by doping."

According to the news reporters, the research concluded: "The highly active nanoparticles (0.02Gd(3+)/TiO2 and 0.01Eu(3+)/TiO2) were applied for industrial wastewater treatment using solar radiation as a renewable energy source."
