One‐pot selective conversion of glucose is a green approach compared with petroleum‐based processes to produce 1,2‐propylene glycol (1,2‐PG), but its realization is hindered by various side reactions. Here we demonstrate a feasible strategy of Pt/SiO 2 @Mg(OH) 2 core‐shell catalyst to achieve the 1,2‐PG yield of 53.8 % by a three‐pronged promotion, including enhancement of the glucose‐fructose isomerization and retro‐aldol condensation (RAC), as well as re‐conversion of by‐product hexitol into 1,2‐PG. We realized the in situ synthesis of the core‐shell structure using a self‐existent Mg(OH) 2 base instead of an extraneous base in the hydrothermal process and it achieved a stable performance during reuse by protecting Pt from leaching.
