... Cr(III) sorbed onto montmorillonite, both alone and coprecipitated with Al. The 27 Al MAS NMR revealed that Cr in the coprecipitated hydroxy interlayer created a second environment for Al, slightly more shielded than that of Al in the montmorillonite 2:1 layer. This observation is evidence...

... of the present study was to determine the effectiveness of hydroxy Fe/Al-intercalated montmorillonites (Fe/Al-Mt) as photo-Fenton catalysts. In particular, different Fe/Al molar ratios were of interest as a means to vary catalytic activity. Intercalation was achieved via an ion-exchange method and brilliant...

... on the diagenesis of muds during deep burial. With depth the montmorillonite in these montmorillonite-rich shales is altered to mixed-layer illite-chlorite-montmorillonite; the regularity of the mixed-layer phase tends to increase with depth. Much of the interlayer hydroxy material is A1 and Fe, acquired before...
