之前看过一篇文献，也是类似的内容，当然，材料是不一样的，如下图：
很微小的差异，文中所述：...the -OH stretching vibrations at 3420 cm-1 also shifted to higher frequencies. The result indicated that the surface M-OH was active site and the quantitative substitution of the M-OH groups by F- played a key role in F- adsorption.
只用IR基本也能说明问题，文献是Journal of Hazardous Materials
