Achieving high‐selectivity conversion of lignin to value‐added chemicals and biofuels remains a desirable but challenging target due its complex structure with multiple reaction paths. Herein, we designed the robust Pt single‐atom sites supported on NiAl layered double hydroxide (Pt1/NiAl‐LDH) intermetallic compound (Pt1/NiAl‐IMC) distinct local charge density for selectivity‐controllable hydrodeoxygenation lignin. The Pt1/NiAl‐LDH electron‐deficient hydrogenated 4‐propylguaiacol into...
