Fund Project: This work was supported by National Natural Science Foundation of China (21271153, 21373181, 21222307, U1402233), Major Research Plan of National Natural Science Foundation of China (91545113), and the Fundamental Research Funds for the Central Universities (2014XZZX003-02).

The solvent-free oxidation of benzyl alcohol was studied using supported Pd-Ni bimetallic nanopar-ticles. Compared with monometallic Pd, the addition of Ni to Pd was found to be effective in sup-pressing the nondesired product toluene, thereby enhancing the selectivity towards benzaldehyde. This result was attributed to a dual effect of Ni addition:the weakening of dissociative adsorption of benzyl alcohol and the promotion of oxygen species involved in the oxidation pathway.
