主 题:iron carbon nanotube titania rhodamine B photocatalytic activity photo-Fenton
摘 要:The composites comprising Fe-carbon nanotubes(CNTs) on TiO2 were prepared by a modified sol-gel method and characterized by nitrogen adsorption,scanning electron microscopy,transmission electron microscopy,X-ray diffraction,and energy dispersive X-ray *** photocatalytic decomposition of rhodamine B(Rh.B) under UV irradiation and air aeration catalyzed by the composites was *** photocatalytic activity of TiO2 nanoparticles was significantly enhanced by the large CNT network that facilitated electron transfer between adsorbed Rh.B molecules and the catalyst substrate and the simultaneous occurrence of the photo-Fenton reaction in the presence of Fe particles.A marked acceleration of the decomposition rate was observed with aeration by flowing air aeration due to the formation of the circulatory photo-Fenton *** oxygen demand of piggery waste was measured at regular intervals to evaluate the mineralization of wastewater.
