近日，苏徽教授再次以共同一作身份在《德国应用化学》发表学术论文，署名单位为“光能转换材料湖南省高校重点实验室”。论文题目：Electrosynthesis of α-Amino Acids from NO and other NO_x species over CoFe alloy-decorated Self-standing Carbon Fiber Membranes（在钴铁合金修饰的自支撑碳纤维膜上由NO及其他NO_x电合成α-氨基酸）。

The conversion of industrial exhaust gases of nitrogen oxides into high-value products is significantly meaningful for global environment and human health. And green synthesis of amino acids is vital for biomedical research and sustainable development of mankind. Herein, we demonstrate an innovative approach for converting nitric oxide (NO) to a series of α-amino acids (over 13 kinds) through electrosynthesis with α-keto acids over self-standing carbon fiber membrane with CoFe alloy. The essential leucine exhibits a high yield of 115.4 μmol h^-1 corresponding a Faradaic efficiency of 32.4%, and gram yield of products can be obtained within 24 hours in lab as well as an ultra-long stability (>240 h) of the membrane catalyst, which could convert NO into NH₂OH rapidly attacking α-keto acid and subsequent hydrogenation to form amino acid. In addition, this method is also suitable for other nitrogen sources including gaseous NO₂ or liquidus NO₃^–  and NO₂^–. Therefore, this work not only presents promising prospects for converting nitrogen oxides from exhaust gas and nitrate-laden waste water into high-value products, but also has significant implications for synthetizing amino acids in biomedical and catalytic science.
