Due to its widely green and sustainable properties, cellulose is identified as a green and sustainable alternative for the preparation of valuable biofuels and chemicals. In this study, Poly‐Pickering HIPEs (PHs) was synthesized as the precursor by using Pickering high internal phase emulsion (HIPE) as templates and PHs‐SO 3 H was prepared after sulfonation treatment. We chemically grafted UiO‐66(Hf)‐type MOFs onto PHs‐SO 3 H in order to synthesize a novel catalyst for the transformation of cellulose into 5‐HMF, which made clear that HMF yield was improved in the presence of the catalyst. What's more, the 5‐HMF yield of 49.6% was obtained under the optimal conditions of 50 mg cellulose, 30 mg catalyst, 60 min of reaction time and 120 °C of reaction temperature. The catalyst is recyclable four cycles without crucial loss of catalytic activity.
