An efficient CoAuPd/C catalyst for hydrogen generation from formic acid at room temperature.
Nowadays, searching for the effective hydrogen (H2) storage/ generation materials remains one of the most difficult challenges toward a fuel-cell-based H2 economy as a longterm solution for secure energy in future. Formic acid (FA, HCOOH), a major product of biomass processing with highenergy density, nontoxicity, and excellent stability at room temperature, has recently attracted tremendous re...
متن کاملHydrogen generation from formic acid decomposition with a ruthenium catalyst promoted by functionalized ionic liquids.
Hydrogen has attracted increasing attention as an important alternative secondary energy resource particularly when combined with fuel-cell technology, which may play a very significant role in power generation in the future. Currently most H2 is produced industrially by methane or alcohol reforming and by the water–gas-shift reaction at high temperatures. However, special purification steps ar...
متن کاملReaction of atomic hydrogen with formic acid.
We study the reaction of atomic hydrogen with formic acid and characterize the radical products using IR spectroscopy in a Kr matrix and quantum chemical calculations. The reaction first leads to the formation of an intermediate radical trans-H2COOH, which converts to the more stable radical trans-cis-HC(OH)2via hydrogen atom tunneling on a timescale of hours at 4.3 K. These open-shell species ...
متن کاملPd/C Synthesized with Citric Acid: An Efficient Catalyst for Hydrogen Generation from Formic Acid/Sodium Formate
A highly efficient hydrogen generation from formic acid/sodium formate aqueous solution catalyzed by in situ synthesized Pd/C with citric acid has been successfully achieved at room temperature. Interestingly, the presence of citric acid during the formation and growth of the Pd nanoparticles on carbon can drastically enhance the catalytic property of the resulted Pd/C, on which the conversion ...
متن کاملEnhanced hydrogen production from formic acid by formate hydrogen lyase-overexpressing Escherichia coli strains.
Genetic recombination of Escherichia coli in conjunction with process manipulation was employed to elevate the efficiency of hydrogen production in the resultant strain SR13 2 orders of magnitude above that of conventional methods. The formate hydrogen lyase (FHL)-overexpressing strain SR13 was constructed by combining FHL repressor (hycA) inactivation with FHL activator (fhlA) overexpression. ...
