| Abstract: | A crosslinked hydrotalcite with pyrophosphate was synthesized and its intercalation and crosslinking were studied by XRD,FT IR,DTA TG, 27 Al and 31 P MASNMR techniques.It is proposed that the amount of H 2P 2O 7 2- anion intercalated into the interlayer space of the hydrotalcite is the most.When calcination at high temperature, it forms P 2O 7 4- pillars and crosslinks to the layer of the hydrotalcite.The product has a surface area of 87m 2/g. |
