Direct hydroxylation of aromatic compounds was effectively achieved by using a newly developed Pd membrane reactor in which the Pd membrane is thin enough (ca. 1 μm) to allow permeation of hydrogen below 500 K. In this reactor, the active oxygen spe

A stepwise examination for the direct synthesis of phenol from benzene was attempted to clear a so-called reductive oxidation process in the reaction system using a catalytic palladium membrane. It was suggested that the oxygen activated by the activ
