Abstract: Alanine as a versatile chemical can be synthesized by catalytic amination of biomass-derived polylactic acid (PLA) in ammonia. However, accelerating the production rate of alanine with high selectivity through the chemical upcycling of PLA waste remains a great challenge. Herein, we proposed Ru/Ce−In-mixed metal oxide (MMO) catalysts with decoration of indium and found that they could efficiently facilitate the amination of PLA into alanine with a high selectivity toward alanine. Among the Ru/Ce− In-MMO cataly… Show more
