Liquid-phase chemical hydrogen storage materials

MnOx-Promoted PdAg Alloy Nanoparticles for the Additive-Free Dehydrogenation of Formic Acid at Room Temperature

“…1−3 In this context, formic acid (HCOOH, FA), which is one of the major stable and nontoxic products formed in biomass processing, has recently attracted significant attention as a potential hydrogen carrier for fuel cells designed toward portable use. 4,5 In the presence of metal catalysts, FA can be decomposed catalytically via dehydrogenation (1) and/or dehydration (2) pathways. …”

Reversible catalytic dehydrogenation of alcohols for energy storage

“…Hydrogen, which may be used in fuel cells or internal combustion engines, is best-suited for longer-term energy storage and can be stored in the form of a compressed gas or a cryogenic liquid or chemically bonded in hydrides (1). The most attractive hydrogen storage media are liquid organic hydrogen carriers (LOHCs), because they have relatively high hydrogen content and can be transported and distributed using the existing liquid fuel infrastructure (2)(3)(4)(5).…”

Formate production through biocatalysis

“…Clostridium carboxidivorans is a member of the genus that displays acetogenic metabolism, utilizing oxides of carbon in combination with hydrogen to articLe addendum articLe addendum energy requirements for the reactions as well as the complicated distillation processes to separate the reactants and products of the methyl formate hydrolysis, 19 which therefore contributes to CO 2 emissions instead of abating them. Intense effort has been directed toward generation of metal complex catalysts for formate production from CO 2 ; 20 however, in addition to being expensive, they generally require concentrated and purified reactants and strongly basic reaction conditions and high pressures, as well as generate reduction byproducts. The superior catalytic performance of enzymes which are cheaper and operate efficiently under mild reaction conditions while displaying considerably less stringent reactant requirements makes them much more desirable catalysts for such a reaction.…”
