Abstract Phase engineering of metal sulfides offers a promising strategy to enhance the catalytic performance by adjusting their atomic arrangement and electronic structure. However, achieving continuous phase‐controlled elucidating structure‐performance relationship remains significant challenge. Herein, for first time, novel class palladium‐sulphur nanosheet aerogels (Pd─S NAs) aimed at enhancing electrocatalytic waste polymer‐derived ethylene glycol oxidation reaction (EGOR) is introduced. Remarkably, benefiting from ordered arrangement, Pd 3 S NAs with 4 phase deliver superior toward EGOR, surpassing both S‐doped (Pd 9 amorphous 1 NAs. Density functional theory calculations reveal that different vital structural descriptor performance, where structure intrinsic contribution excellent Compared other Pd─S NAs, have regular arrangements, which promote carbon monoxide intermediate ( * CO), cause optimal adsorption CH₂OHCOO key intermediates during facilitate selective EG glycolic acid, lower barrier in potential determining step reaction, thus presenting EGOR performance. This study advances synthesis Pd‐based nanomaterials highlights importance phase‐dependent properties electrocatalysis.
