Abstract Biodegradable polyesters, such as polylactic acid (PLA), is one of the most promising plastics with great potential to contribute enabling a sustainable global circular economy. However, efficient chemical upcycling PLA plastic waste into high‐value chemicals remains grand challenge. Herein, series Ru/CeFeO x catalysts varying Ru loadings were developed for catalytic amination alanine in presence ammonia. The as‐prepared exhibited exceptional activity, high selectivity, and excellent recyclability, achieving an yield 70.5 % at 180 °C 18 h, significantly surpassing previous reports. outstanding performance can be primarily attributed Fe species , which generated more oxygen vacancies, provided abundant base sites, enhanced reducibility, therefore accelerating reaction rate enhancing efficiency. This study presents alternative strategy realization

Abstract Solar‐driven photocatalysis is a promising strategy for clean hydrogen (H 2 ) generation cooperated with selective organic synthesis. Lignin, rich in aromatic units and functional groups, serves as an ideal hole sacrificial agent substrate, facilitating H evolution yielding high‐value chemicals/fuels. To boost overall photocatalytic redox efficiency, thermal catalysis was further combined to enhance the transfer activity of photo‐generated carriers. And highly controllable Cu‐based catalyst developed using technical lignin‐carbon electron buffer. The active‐pyrolyzed layer precisely regulated crystal dispersion Cu species on Cu/SiO , simultaneously dynamically constructing active electron‐rich 0 electron‐deficient σ + (1 < ≤ 2) sites. Excellent thermo‐photo performances were achieved, rate up 1313.2 μmol·g cat −1 ·h yield 45.2% C13–C16 dimers from lignin monomers. This study reveals utilization catalysts, well efficient production jet fuel precursors.
