Selective Hydrogenation of Citral on Pt-Containing Catalysts at Room Temperature and Atmospheric Pressure

Russian Journal of Physical Chemistry A - It is shown that the 1% Pt/CeO2–ZrO2 (1% Pt/CZ) catalytic system allows selective hydrogenation of citral with a 94% conversion and a selectivity...     

Hydrogen spillover on cerium-based catalysts

Data on hydrogen spillover (HS) in catalytic processes are systematized. Different opinions on the mechanism and participation of HS in various reactions are presented. Hydrogen spillover on CeO₂-based systems and physicochemical methods of investigation of the phenomenon are considered. Tentative mechanisms of HS are described and the role of HS in catalytic hydrogenation reactions is studied.
