Studies from Tongji University Reveal New Findings on Environmental Calalysis

June 6, 2014



By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- New research on Environmental Calalysis is the subject of a report. According to news reporting out of Shanghai, People's Republic of China, by VerticalNews editors, research stated, "The disposal of sewage sludge, which is produced numerously by wastewater treatment plants worldwide, is currently one of the most important environmental issues. Here we devised an alternative way of converting sewage sludge into mesoporous material (SS-Fe-350) through a facile synthesis method that resulted in an effective and stable heterogeneous catalyst for photo-Fenton reaction."

Our news journalists obtained a quote from the research from Tongji University, "X-ray diffraction, N-2 sorption isotherms and scanning electron microscope analysis indicated the existence of alpha-Fe2O3 within the pores of mesoporous SS-Fe-350 nanocomposite. The original dozens of mg/g of Fe content in the sewage sludge were also collectively identified as the catalytic site. A kinetic analysis showed that SS-Fe-350 exhibited rapid rhodamine B degradation and mineralization under UV light irradiation conditions and p-nitrophenol degradation and mineralization under both UV and visible (lambda > 400 nm) light irradiation conditions. The possible reaction mechanism was investigated by the electron spin resonance technique. Moreover, SS-Fe-350 exhibited an excellent stability of catalytic activity and low Fe-ion leaching (

According to the news editors, the research concluded: "This protocol provides an alternative environmentally friendly sewage sludge reuse method and a facile mesoporous material derived from sewage sludge that effectively degrades azo-dye and refractory organic pollutants."
