Schematic of asymmetric reaction rate control based on the steric donor–acceptor geometry of protons

Caption

(Left) Increasing steric hindrance raises the energy barrier of the hydrogen evolution reaction, while the nitrogen reduction reaction remains largely unaffected.

(Right) Greater steric hindrance maintains selectivity over a wider range of reduction voltages.
