Efficient transformation of biomass‐derived feedstocks to chemicals and fuels remains a daunting challenge in utilizing biomass as alternatives to fossil resources. A three‐phase catalytic system, consisting of an aqueous phase, a hydrophobic ionic‐liquid phase, and a solid‐acid catalyst phase of nanostructured vanadium phosphate and mesostructured cellular foam (VPO–MCF), is developed for efficient conversion of biomass‐derived fructose to 5‐hydroxymethylfurfural (HMF). HMF is a promising, versatile building block for production of value‐added chemicals and transportation fuels. The essence of this three‐phase system lies in enabling the isolation of the solid‐acid catalyst from the aqueous phase and regulation of its local environment by using a hydrophobic ionic liquid, 1‐butyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][Tf 2 N]). This system significantly inhibits the side reactions of HMF with H 2 O and leads to 91 mol % selectivity to HMF at 89 % of fructose conversion. The unique three‐phase catalytic system opens up an alternative avenue for making solid‐acid catalyst systems with controlled and locally regulated microenvironment near catalytically active sites by using a hydrophobic ionic liquid
