We report SiO2-supported monometallic Pt,Pd,Au,Ni,Cu and Co catalysts for proton-driven NAD+regen-eration,co-producing H2.All metals are fully selective to NAD+where the order of turnover frequencies(Pt＞Pd＞Cu＞Au,Ni and Co)coincides with those otherwise observed in electrochemical hydrogen evolution reactions.This has revealed that NADH is capable of converting the metal sites into a"cathode"without an external potential and the NADH to NAD+reaction involves transferring electron and hy-drogen atom separately.Electron-deficient Ptδ+(on CeO2)enhances TOF and the heterogeneous Pt/CeO2 catalyst is recyclable without losing any activity/selectivity.
