MIL‐101, a chromium‐based metal–organic framework, is known for its very large pore size, large surface area and good stability. However, applications of this material in catalysis are still limited. 5‐Hydroxymethylfurfural (HMF) has been considered a renewable chemical platform for the production of liquid fuels and fine chemicals. Phosphotungstic acid, H 3 PW 12 O 40 (PTA), encapsulated in MIL‐101 is evaluated as a potential catalyst for the selective dehydration of fructose and glucose to 5‐hydroxymethylfurfural. The results demonstrate that PTA/MIL‐101 is effective for HMF production from fructose in DMSO and can be reused. This is the first example of the application of a metal–organic framework in carbohydrate dehydration.
