Improved Raman interpretation of covalently functionalized MWCNTs arises from the distinction between spectral features related to aromaticity disruptions within the sidewalls and within the inner tubes.
Magnetic core-double shell silica nanosupports functionalized with amine and thiol groups successfully immobilized Au NPs, producing novel magnetically recyclable nanocatalysts for the reduction of 4-nitrophenol in water in the presence of NaBH 4 .
