New bimetallic copper-titanium hydrogen evolution catalyst outperforms platinum by more than 2x
Green Car Congress
MARCH 17, 2015
Regardless of acidic or basic conditions, Pt, along with its alloys, is the benchmark electrocatalyst that requires very small overpotentials to drive the reaction, whereas the scarcity and high cost of Pt hinder its large-scale use for H 2 production. … The two Cu-Cu-Ti hollow sites exhibit HBE values close to that of Pt.
