Structural disorder accelerates the kinetics of electrocatalytic reactions

snip 20170530174702Operando experiments at beamline ID31 revealed an important link between structural defects in PtNi/C nanoparticles and an enhancement of the kinetics of the oxygen reduction reaction. Subsequently, by designing structural disorder into the system, a new class of catalyst has been developed with performance comparable to the best shape and composition controlled nanocatalysts but with higher stability.
