The volcanic relationship between the HER activity and lattice constant of RuCo alloy nanofilms

Abstract

RuCo-ANFs with different proportions can be successfully prepared by magnetron sputtering, and their lattice constants can be adjusted accurately. In the RuCo-ANF, there is an obvious electronic interaction between Ru and Co, thus adjusting the ΔG_H* on its surface. There is a volcanic relationship between the HER activity and the lattice constant of RuCo-ANF.
