abstract	The microporous framework copper silicates CuSH-1NaK (1) and SGU-29 (2) - prepared using hydrothermal conditions - are effective heterogeneous oxidation catalysts for producing benzaldehyde (BzAld) and benzoic acid (BzAcid) from benzyl alcohol (BzOH), under mild reaction conditions (approximately atmospheric pressure, 70 degrees C). The copper silicate heterogeneous catalysts triggered a radical reaction mechanism leading to the target products; in particular, BzAcid was formed in up to 94 % yield and 100 % selectivity from BzAld. The type of oxidant and solvent influenced the catalytic performances.
