The Cover Feature shows how carbon nanotubes can promote an efficient and selective production of 5‐hydroximethylfurfural (HMF) from cellulosic biomass. It is well known that HMF is an intermediate reaction product in the acid hydrolysis of sugars and cellulose. In aqueous systems, this chemical undergoes further undesired side reactions. Although these side reactions are avoided in organic media, performing this reaction in biphasic systems leads to a decrease of the overall HMF yield as the process is controlled by the interphase mass transfer. In this work, the use of carbon materials (such as carbon nanotubes) is proposed for promoting interphase mass transfer. Carbon materials can adsorb HMF in the aqueous phase and desorb it into the organic phase, thereby, increasing the overall mass transfer.
