A review of formic acid decomposition routes on transition metals for its potential use as a liquid H2 carrier

Hydrogen production from chemical hydrogen storage materials over copper‐based catalysts

“…[69][70][71][72][73][74][75] The HCOOH decomposition reaction may involve intermediates such as formates (HCOO*) or carboxylates (COOH*), which are produced by activating the O-H or C-H bond in HCOOH molecules. 410,411 Formates can appear either as a bidentate configuration on two adjacent metal atoms (HCOOB*) or as a monodentate configuration on a single metal atom (HCOOM*). 411,412 398 The dehydrogenation of HCOOH over Cu catalysts is considered to proceed through the HCOOB* pathway, as demonstrated by spectroscopic studies that detected HCOOB* species when HCOOH was exposed to Cu (100) or Cu (110) surfaces.…”

“…The reaction mechanism of FA over a pure Cu surface has been deeply studied 69–75 . The HCOOH decomposition reaction may involve intermediates such as formates (HCOO*) or carboxylates (COOH*), which are produced by activating the O‐H or C‐H bond in HCOOH molecules 410,411 . Formates can appear either as a bidentate configuration on two adjacent metal atoms (HCOOB*) or as a monodentate configuration on a single metal atom (HCOOM*) 411,412 .…”

Desalting biocrude for improved downstream processing toward marine fuel application

“…[29][30][31][32][33][34] It is also proposed for use as a hydrogen carrier in energy applications. 35,36 Following the wash studies, hydrotreating of the washed and unwashed biocrudes was compared. Preliminary TEA of a hypothetical biocrude desalting-wash process is also presented.…”

Reverse fabrication method of thin-film composite membranes for hydrogen separation

“…3 Hydrogen, with its superior combustion energy and minimal environmental impact, emerges as a promising renewable energy source, demanding efficient hydrogen separation technology for obtaining high-purity hydrogen from industrial gases. 4,5 Traditional methods for hydrogen separation, such as pressure swing adsorption and cryogenic distillation, are marked by excessive energy consumption, constituting a substantial portion of overall plant costs. 6 In response, membrane separation stands out as a next-generation gas separation method, prized for its low cost, minimal carbon footprint, ease of application, and high energy efficiency.…”
