- W2369184230 abstract "Mesoporous TiO2 microspherical photocatalysts were prepared through a controlled crystallization-continuous precipitation method using titanous sulphate and ammonium bicarbonate as raw materials.The microstructure,composition and photocatalytic properties were characterized by SEM,XRD and UV-Vis spectrophotometer and chemical oxygen demand(COD),respectively.The results indicate that the asprepared TiO2 samples belong to anatase crystal phase and exhibitspherical or spheroidal morphology with the particle size of 5to 30μm and crystallite size less than 14nm.Themicrospherical TiO2 is a typical mesoporous material with a large specific surface area of~138m2/g and a narrow pore diameter distribution in the range of 4to 10nm.They have also an excellent photocatalytic activity to degrade methyl orange solution,and the decoloration rate of methyl orange solution can exceed 95%.Meanwhile,the TiO2 microspheres show a good sedimentation performance to recover TiO2,and re-utilization for many times." @default.
