The Impact

AbstractWe report herein the results of density functional theory calculations of the geometric and electronic structure for a series of fused heterocyclic compounds. These molecules were compared with the corresponding carbocyclic oligoacenes, which are currently being experimentally investigated for use as organic semiconductors. The impact of various structural modifications on this class of compounds on the calculated structures is examined. The results of our calculations reveal that such materials hold exceptional promise as organic semiconductors.

Formic Acid Decomposition

By performing density functional theory calculations, the adsorption configurations of formic acid and possible reaction pathway for HCOOH oxidation on PtPd(111) surface are located. Results show that CO2 is preferentially formed as the main product of the catalytic oxidation of formic acid. The formation of CO on the pure Pd surface could not possibly occur during formic acid decomposition on the PtPd(111) surface owing to the high reaction barrier. Therefore, no poisoning of catalyst would occur on the PtPd(111) surface. Our results indicate that the significantly increased catalytic activity of bimetallic PtPd catalyst towards HCOOH oxidation should be attributed to the reduction in poisoning by CO.
