    • note
    • The transfer reduction rate was found to depend critically on the counterion of the formates, the ionic size of which determines the hydrogen-donating ability thus the dehydrogenation efficiency of the formate salts (see Table S1 and Ref. [4d]). On the other hand, the addition of a base such as potassium acetate to HCOOH accelerated the aldehyde reduction rate (see Figure S9) further confirms that HCOO ion is essential for the reaction to proceed.

    • note
    • Based on the GC-MS analysis, no hydrogen was generated during the process of the Au/meso-CeO2-catalyzed TH of aldehydes, which indicates that the encountered reduction was a true hydrogen transfer rather than a consecutive dehydrogenation-hydrogenation ACHTUNGTRENUNGreaction.
