mesoporous molecular sieve Ti-KIT-1%post-synthetic method%structural performance%used of a titanium source effectively
Mesoporous molecular series Ti-KIT-1 samples were prepared by three different post-handling methods using Ti(OEt)4 as the Ti source and KIT-1 as the support .The three post-synthetic methods were impregnated method,grafting method and colloidal method.The Ti-KIT-1 samples were characterized by FT-IR,DRS,XRD,TG-DSC and physical adsorption-desorption of nitrogen.Experimental results showed that the Ti-KIT-1 samples remained the original mesoporous structure with a smaller specific BET surface area compared to the parent KIT-1 sieve.DRS and FT-IR indicate the existence of tetrahedral titanium (Ⅳ),TG-DSC and chemical analyse method proved that TiO_2 weight percentage of grafting sample is much more than impregnated and colloidal samples.The grafting method is a good post-handling method that can effectively make use of a titanium source and promise the original mesoporous structure.
