Steering no Dimerization Through Boron‐Enhanced Spin–Orbit Coupling in Ultrathin PdCuB Nanosheets for Durable N2‐Selective Nitrate Reduction
The selectivity bottleneck of electrochemical nitrate‐to‐N2 conversion is kinetic rather than thermodynamic: dimerization of two adsorbed *NO intermediates is spin‐forbidden, imposing a kinetic barrier invisible to conventional thermodynamic analyses. Spin–orbit coupling (SOC) offers the principal channel for the requi...
