pH-dependent hydrogen evolution using spatially confined ruthenium on hollow N-doped carbon nanocages as a Mott–Schottky catalyst
Bidushi Sarkar, Debanjan Das, Karuna Kar Nanda
Abstract
We demonstrate Ru nanoparticles confined on a N-doped hollow carbon matrix as a wide pH hydrogen evolution electrocatalyst. The formation of a Mott–Schottky heterojunction at the strongly coupled Ru/N-doped C interface enhances the catalysis.
