is a rising and attractive method for efficient amino acid production. However, industrial-grade electrosynthesis of high-value amino acids from simple carbon and nitrogen substrates is confronted with a great challenge. Herein, we design a dual-site PbBi alloy catalyst for various amino acids' electrosynthesis from keto acids and nitrate. An alanine Faradaic efficiency of 59.7% is delivered at -1.5 V vs SCE, reaching the industrial current density of 570 mA cm^-2 with high catalytic durability of the porous Pb₁Bi_0.1 catalyst. In the tandem reaction process, nitrate is first converted to NH₂OH via electrochemical reduction mainly over the Bi site. Then the obtained NH₂OH integrates with the α-keto acid to form the oxime intermediate. Lastly, the Pb site facilitates the electroreduction of oxime to the final amino acids. More importantly, over 10 kinds of α-amino acids can be successfully synthesized in excellent FE and high yield at high current density, indicating the superior catalytic activity and wide universality of our strategy. In short, this work opens up a novel approach to realize the one-pot electrosynthesis of various amino acids from renewable biomass feedstocks and nitrate waste industrially.26:T473,Biomass is a renewable carbon source that comes from plants, containing chemical energy from the sun. Nitrate, which is a N-containing feedstock with a lower dissociation energy, has a rich distribution in wastewater. Renewable biomass and nitrate waste can be converted into valuable C–N products through photocatalytic processes, which is becoming promising but challenging in the production of different kinds of chemicals and fuels. Herein, we report the photoconversion of biomass and nitrate into glycine with a 765 μmol gcat–1 h–1 production rate and 15.3% yield over a Ba2+-modified TiO2 catalyst. The process cascades multiple reactions containing the photoreforming of biomass to glycol, nitrate reduction to NH3, and finally, C–N coupling to glycine, among which nitrate ions play a dominant role in the selective cleavage and oxidation of biomass. Surprisingly, after hydrolysis pretreatment, biopolyols or sugars and even raw wood sawdust could react with nitrate to generate glycine. This study provides an effective catalytic system to produce glycine from renewable biomass and nitrate waste under mild conditions.
