Direct alcohol fuel cells (DAFCs) have aroused great interest for portable electronic devices and electric vehicles due to their high power density output and low pollutant emissions. Ethanol is the most attractive of the possible low-molecularweight alcohols that can be used, because it is a sustainable fuel that can be produced in large volumes by the fermentation of biomass. Furthermore, compared with methanol, ethanol is less toxic and more convenient, has a higher energy density, and appears to fulfill most fuel requirements for low-temperature fuel cells.[1] Even though platinum and platinum-based catalysts show a high efficiency towards ethanol electrooxidation,[2] the high cost and limited supply of platinum prevent the commercial development of direct ethanol fuel cells (DEFCs). Therefore, the search for efficient, durable, and most importantly, inexpensive alternative materials to Pt-based catalysts is of utmost importance.[3]Metal–organic frameworks (MOFs) show promising catalytic activities for alcohol oxidation, in hydrogenation reactions, Knoevenagel condensations, ring opening of epoxides, and epoxidation of olefins.[4] We believe the following unique properties of MOFs make them good candidates as catalysts for the above-mentioned specific reactions. First, they possess various pore sizes (3–35) and surface areas (500–6500 m2 gÀ1).[5] Second, their surface properties can be manipulated using a variety of organic ligands, affording unique functionalities on the channel surface. For example, specific
