A Pt/CeO2‐ZrO2 catalytic system was able to initiate an extremely intense hydrogen spillover providing a huge amount of activated hydrogen (12 mol/mol Pt) at temperatures –50°C ‐ +25°C, which was not observed before. The idea was to use this activated hydrogen for reduction of carbonyl compounds under ambient conditions. Thus, the efficient and selective heterogeneous hydrogenation of carbonyl compounds of different structure, including 5‐hydroxymethylfurfural and cinnamaldehyde, to the corresponding alcohols with quantitative yields was successfully performed over the Pt/CeO2‐ZrO2 catalysts at room‐temperature and atmospheric pressure of H2. The proposed catalysts afforded hydrogenation under significantly milder conditions with a much higher activity and selectivity compared to the commercial catalysts and reported catalytic systems. Hydrogenation of the C=O bond in the presence of a C=C bond proceeded with a high regioselectivity.

The use of available renewable sources of raw materials for the production of various organic compounds has long been undoubted and recognized throughout the world. However, the development of efficient “green” catalytic technologies for the processing of bioavailable compounds, namely, the synthesis of catalysts and the selection of optimal process conditions, has become a real challenge for researchers nowadays. In this work, 2,5-bis­(hydroxymethyl)­furan, an intermediate for the production of a number of biobased polymer materials, was obtained by hydrogenation of 5-hydroxymethylfurfural in a yield close to quantitative at room temperature and atmospheric pressure in the presence of a catalytic system with 1% wt of platinum as an active phase supported on ceria–zirconia mixed oxide. On the low-loaded 0.25% Pt/CeO2–ZrO2 catalyst, the yield of the desired alcohol as high as 87% has been achieved after a slight increase of H2 pressure from 0.1 to 0.5 MPa.
