Abstract

Amino acids serve as the fundamental building blocks of proteins and constitute an indispensable material basis for all life systems. Electrochemical conversion of nitrogen oxides (NOx) offers a sustainable, environmentally benign route for amino acid synthesis, yet it is plagued by unsatisfactory selectivity and stability originating from competing multi-step reaction pathways. Herein, we report a metal−organic framework (MOF)-guided engineering strategy for the fabrication of bismuth nanoparticles (Bi NPs), which delivers a high yield of glycine corresponding a selectivity exceeding 97% and without decay after eight cycles. The performance outperforms most of the reported electrocatalysts. Mechanistic investigations reveal that the strong electronic interaction between Bi NPs and the MOF host enables precise regulation of the electronic structure of Bi NPs via grafting functional substituents onto the MOF framework, thereby promoting the highly selective conversion of NOx to target amino acid products. This work provides a versatile platform for the rational design of advanced electrocatalysts, opening new avenues for sustainable electrochemical synthesis of high-value-added chemicals.
