Boosting efficient ambient nitrogen oxidation by a well-dispersed Pd on MXene electrocatalyst

Abstract

An electrochemical nitrogen oxidation approach has been realized experimentally by a Pd-decorated MXene (Ti₃C₂T_x, T = F and O) electrocatalyst under ambient conditions. The Pd-MXene catalyst can achieve a desirable nitrate yield rate of 2.80 μg h⁻¹ mg_cat⁻¹ (equivalent to 45.16 μmol h⁻¹ g_cat⁻¹ HNO₃) as well as a high nitrate faradaic efficiency of 11.34% in a favorable neutral pH environment.
