abstract = "This contribution studied Pd based catalysts supported on graphene
derivatives (reduced graphite oxide and CeO2-rGO hybrid),
synthesized under hydrothermal conditions, evaluating the thermal
stability and interactions metalsupport. XRD of 1Pd/rGO and
1Pd/5Ce/rGO showed diffraction lines corresponding to Pd0 ,
suggesting an intimate contact between Pd and rGO. The Pd0
presence after synthesis is unusual in catalysts prepared by
conventional methodologies. The behavior described here can be
attributed to a strong interaction between Pd and oxygenated
groups of graphite oxide (precursor) under hydrothermal synthesis.
In contrast, XRD pattern and Raman Spectrum of 1Pd/5Ce/rGO denote
CeO2 has segregated over the support without appreciable
interaction. Concerning to the thermal stability, both samples rGO
and 1Pd/rGO presented high thermal resistance (> 500°C) while upon
Ce addition the temperature of degradation decreased drastically
(~320°C). Raman Spectroscopy of rGO based sample showed the
hydrothermal treatment lead to defects presence which is
beneficial for catalysis purposes.",
