Kontrollierte Wasserstofferzeugung aus Ameisensäure‐Amin‐Addukten bei Raumtemperatur und direkte Nutzung in H₂/O₂‐Brennstoffzellen

Abstract

Munteres Blubbern: Bei Raumtemperatur wurde Wasserstoff aus Ameisensäure‐Amin‐Addukten freigesetzt und direkt in einer Brennstoffzelle verwendet (siehe Bild des Versuchsaufbaus). Ruthenium‐Phosphan‐Systeme dienten als Katalysatoren in dieser Transformation.

Selective Formic Acid Decomposition for High‐Pressure Hydrogen Generation: A Mechanistic Study

“…[14] Independently, Beller et al developed a method for hydrogen generation by decomposition of formic acid/amine mixture. [15] In this paper a detailed kinetic and in situ spectroscopic study of our system, leading to a tentative mechanistic cycle, is reported.…”

Decomposition of Formic Acid Catalyzed by a Phosphine‐Free Ruthenium Complex in a Task‐Specific Ionic Liquid

“…[18][19][20][21][22] FA decomposition to hydrogen and carbon dioxide can easily be catalyzed by several homogeneous [14,16,[18][19][20][21][22][23] and heterogeneous catalysts. [24] In particular, Ru phosphine complexes in the presence of a base, such as triethylamine or sodium formate, in water are quite effective catalysts for this transformation.…”

Continuous Hydrogen Generation from Formic Acid: Highly Active and Stable Ruthenium Catalysts

“…In our previous work, [8,9] the maximum hydrogen evolution was achieved by applying larger amounts of catalyst (Table 1, significantly increased catalyst activity (Table 1, entries 3, 5-7). Applying the preformed complex [RuH 2 A C H T U N G T R E N N U N G (dppe) 2 ] a similar activity is observed (Table 1, entries 3 and 4).…”

“…[7] In 2008, we and Laurenczy et al independently have demonstrated that hydrogen can be generated from formic acid under mild conditions. [8] Improved catalytic activity was obtained by applying in situ catalysts based on ruthenium and various phosphine ligands. [9] Most recently, we showed that the reaction can be triggered and accelerated by irradiation with visible light.…”
