Palladium is a promising material for electrochemical CO2 reduction to formate with high Faradaic efficiency near the equilibrium potential. It unfortunately suffers from problematic operation stability due CO poisoning on surface. Here, it demonstrated that alloying an effective strategy alleviate this problem.

Lanthanides are widely codoped in persistent luminescence phosphors (PLPs) to elevate defect concentration and enhance efficiency. However, the deleterious cross-relaxation between activators lanthanides inevitably quenches luminescence, particularly heavily doped phosphors.
