Abstract In this paper, Density Functional Theory (DFT) calculations were conducted to study the adsorption and stepwise hydrogenation of acrolein (CH 2 =CHCH=O) on pure Mo 2 C(001) and Pt/Mo 2 C(001). The electronic properties were investigated by Mulliken population analysis. The results showed that Mo atoms obtained some electrons from surrounding Pt and C atoms, thereby enhancing the hydrogenation activity of Mo atoms around Pt atoms and forming local active sites dominated by Mo atoms around Pt atoms. As a result, the adsorption energy of the species on Pt/Mo 2 C(001) is generally higher than that on Mo 2 C(001), and the activation energies of the elementary reactions involved in stepwise hydrogenation of acrolein on Pt/Mo 2 C(001) are lower than those on Mo 2 C(001). Moreover, Pt/Mo 2 C(001) exhibits higher selectivity for C=O bond hydrogenation than Mo 2 C(001) and produces more allyl alcohol.

Single-atom catalysts usually comprise positively charged atomically dispersed metal cations on oxide supports. Neutral atoms on oxides are synthetically challenging, and their performance in catalytic reactions remains ambiguous. Here, we shed light on this question with the design of Pd single-atom catalysts on polyoxometalates. Depending on the composition of the support, Pd can either exhibit oxidation states of 0 or 2+. We show that this difference is decisive for the C-O bond hydrogenolysis while displaying negligible effects on the C=O bond hydrogenation. The selective conversion of 5-hydroxymethylfurfural (5-HMF) to 2,5-dimethylfuran (2,5-DMF), a key renewable fuel compound, was shown to occur at 253 K with reaction rates up to 71.0 per hour.<br>
