A synbio strategy for efficient sugar-to-electricity conversion.

Designing hydrogen evolution reaction catalysts with high performance in alkaline conditions is important for reducing energy consumption during water electrolysis. This study reports an electrodeposition−calcination−electrodeposition strategy to construct the Ni−Mo−O/Ni 4 Mo nanointerface on an Ndoped carbon support derived from polyaniline on carbon fiber paper. The N-doped carbon support not only stabilizes the metal/ metal oxide nanointerface but also generates more active intrinsic sites and electrical conductivity via the metal−N interaction. The obtained Ni−Mo−O/Ni 4 Mo@NC displays a low overpotential of only 61 mV at a current density of 10 mA cm −2 for alkaline HER in 1 M KOH.
