Terrestrial plants contain B70% hemicellulose and cellulose that are a significant renewable bioresource with potential as an alternative to petroleum feedstock for carbon-based fuels. The efficient and selective deconstruction of carbohydrates to their basic components, carbon monoxide and hydrogen, so called synthesis gas, is an important key step towards the realization of this potential, because the formation of liquid hydrocarbon fuels from synthesis gas are known technologies. Here we show that by using a polyoxometalate as an electron transfer-oxygen transfer catalyst, carbon monoxide is formed by cleavage of all the carboncarbon bonds through dehydration of initially formed formic acid. In this oxidation-reduction reaction, the hydrogen atoms are stored on the polyoxometalate as protons and electrons, and can be electrochemically released from the polyoxometalate as hydrogen. Together, synthesis gas is formed. In a hydrogen economy scenario, this method can also be used to convert carbon monoxide to hydrogen.

“…Formate decomposes further to a variety of products, the dominant of which are CO, CO 2 , H 2 O and H 2 . Taking into account these products, the decomposition of formic acid on TiO 2 surfaces has been described in terms of dehydration (to CO and H 2 O) and dehydrogenation (to CO 2 and H 2 ) mechanisms [3][4][5][6][7][8]. Recent studies on single-crystal TiO 2 surfaces revealed that the production of H 2 O and CO could not be directly linked, thus the dehydration reaction can be excluded [9].…”
