Ultra‐low‐loaded supported Pt catalysts showed an extremely high activity in selective hydrogenation of bioavailable 5‐hydroxymethylfurfural (5‐HMF) to the corresponding diol, i.e. 2,5‐bis(hydroxymethyl)furan (BHMF); among the synthesized catalysts with a Pt content varying in the range 0.025–0.25 wt%, the most active one appeared to be the sample 0.1% Pt/CeO2–ZrO2, which allows us to obtain BHMF with a 97% yield and 100% selectivity from 5‐HMF without the use of alkali or any other additives at a temperature of 170 °C and H2 pressure of 1 MPa, with the 5‐HMF:Pt ratio higher than 1000 mol mol–1. © 2021 Society of Chemical Industry (SCI).

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. [ABSTRACT FROM AUTHOR]
