文摘
- •
Nano-Re/SiO2 appeared highly efficient and selective catalyst in glycerol acetalization.
- •
TON for glycerol to solketal (Re/SiO2) significantly outperforms literature values.
- •
Mo supported Re, Ir, Rh, Ru were tested as catalysts in glycerol acetalization.
- •
Re, Ir, Rh and Ru/SiO2 catalytic activity was correlated with electronic properties.
