in high yield, but did not continue to react substantially to FDCA, whereas over Pt/C
and Pd/C FDCA was formed under identical conditions. For Pt/C, up to 80% FDCA
was obtained after 6 h. It was also demonstrated that by increasing the O

pressure and
base concentration FDCA could also be obtained for the supported Au catalysts.
In an attempt to avoid the use of stoichiometric base, Ebitani et al. reported the
use of hydrotalcite materials as recoverable catalyst support and heterogeneous base
[78]. A 1.9 wt% Au/HT catalyst was prepared by deposition precipitation using aque
