The powder X-ray diffraction (XRD) patterns were acquired
on a Simens D5005 diffractometer with CuKα radiation.The
isotherm of N2 was recorded using a Micromeritics ASAP
2010 apparatus; the samples were out-gassed at 523 K for 2 h
before the measurement.Specific surface areas were calculated
by the BET model; pore size distribution was calculated
by the Barrett–Joyner–Halenda formula from the adsorption
isotherm.IR spectra were recorded in air with a Nicolet Impact
410 spectrometer by diluting samples in KBr.IR spectra
in the hydroxyl region was obtained after the samples were pretreated
at 573 K for 3 h under vacuum conditions following
the procedure described before [11].Temperature-programmed
desorption (TPD) was carried out using NH3 or CO2 as probe
molecules according to the procedure described in Ref.[11].
Solid-state 29Si CP-MAS NMR spectra were preformed on a
Varian Infinity Plus 400 spectrometer.

on与CuK¦Á辐射的一个Simens D5005衍射计.N2 isotherm尽快被记录了使用Micromeritics
2010用具; 样品是醉的在523 K 2 h 的before测量.比表面区域是故意的
by赌注模型; 毛孔大小分布被计算了
by从吸附的Barrett¨CJoyner¨CHalenda惯例isotherm.红外光谱在与Nicolet冲击的空气被记录了410分光仪通过稀释在溴化钾的样品.红外光谱在样品是被预处理的之后,in羟基区域获得了at 573 3的h K在真空情况跟随之下
the做法被描述前面[11].温度被编程的
