Formic acid is a promising chemical fuel for fuel cell applications. However, due to the dominance of the indirect reaction pathway and strong poisoning effects, the development of direct formic acid fuel cells has been impeded by the low activity of existing electrocatalysts at desirable operating voltage. We report the first synthesis of Pt(3)Pb nanocrystals through solution phase synthesis a...

Rodents and non-rodent species metabolize methanol to formaldehyde to formic acid to carbon dioxide. There are two major differences, however. Rodents (mice and rats) metabolize methanol to formaldehyde using the enzyme catalase, whereas humans use alcohol dehydrogenase (ADH1). A byproduct of rodent methanol metabolism is hydrogen peroxide, a reactive oxygen species (ROS). ROS may be involved i...

We have investigated the effect of ice substrate on the temperature dependent structural changes of formic acid. Infrared spectra of HCOOH@KBr, HCOOH@H2Oamorphous and HCOOH@H2Ocrystalline were measured in the temperature range of 18–180 K (X@Y represents X deposited on Y). At 18 K formic acid deposited over ice exists principally as its dimer. Upon increase of temperature, the dimer gets conver...

For the binary liquid systems formic acid + acetic acid, formic acid + propionic acid, and acetic acid + propionic acid, we give the results of new calorimetric measurements of the molar excess enthalpy H at 25 °C, 30 °C, 40 °C, and 60°C, covering the entire range of compositions. H is always positive, increases linearly with the temperature, and is slightly asymmetric with respect to the mole ...

We report on the first experimental observation of formic acid dimers composed of two molecules of the higher-energy cis conformer. The cis-cis formic acid dimers are prepared in an argon matrix by selective vibrational excitation of the ground state trans conformer (deuterated form HCOOD) combined with thermal annealing of the matrix at about 30 K. Five cis-cis formic acid dimers are predicted...

Catalytic conversion of formic acid into methanol was investigated with Cu as a catalyst and Al as a reductant under hydrothermal conditions. It was found that formic acid can be converted into methanol by such means. The highest yield of methanol (30.4%) was attained with a temperature of 300 °C and a reaction time of 9 h. The AlO(OH) formed from Al oxidation may also play a catalytic role in ...

The chemical equilibria concerning formic acid are computationally investigated in water over a wide range of thermodynamic conditions. The solvation free energies for relevant C1 compounds are evaluated in the method of energy representation, and are used to assess the solvent effect on the formic acid reactions. In the two competitive decomposition processes of formic acid, the solvent strong...
