Abstract—A ically separated fly ash micro-sphere In this paper, a novel ically separated fly ash
(MSFM) were prepared by citrate sol-gel micro-sphere (MSFM) was prepared with citrate sol-gel
microstructure of the products were tested by SEM and process. Then the TiO2 film photocatalysts immobilized on
was found that the MSFM was coated work of barium MSFM were prepared by sol-gel process. The crystal phase
,
ferrite which exhibited the ic absorption property. Then and morphology of Ti02 micro-sphere were investigated by
the TiO2 film photocatalysts immobilized on MSFM were
XRD and SEM . The photocatalytic activities of Ti02
prepared by sol-gel method. crystal phase and microsphere with diferent prepared condition and the amount
morphology of Ti02 micro-sphere were investigated by XRD and
of Ti02 on micro-sphere were evaluated by degradation of
SEM . The pho
