| 摘 要： | Macroporous titania monoliths were prepared via sol-gel method using polymer foam as templates.The poly-mer foam polymerized via concentrated emulsion polymerization was immerged in a solution of titanium(IV)iso-propoxide in 2-propanol,which underwent a sol-gel process.The organic components were subsequently removedby calcination.The effects of various parameters,including the nature of the monomer,the volume fraction of dis-persed phase of the concentrated emulsion,and concentration of the sol-gel solution were investigated.The SEMmicrographs of the macroporous titania monoliths thus obtained showed that the porous structure of the final mate-rial was effectively controllable.
