“…The pathway of formic acid/formaldehyde dehydrogenation using various catalysts. Data obtained from [27][28][29][30][31][32][33][34][35][36]44,45]. Recently, Singh and colleagues reported the ruthenium-catalyzed dehydrogenation of aqueous formaldehyde and paraformaldehyde to produce hydrogen [45].…”

“…For efficient hydrogen production from formaldehyde, in situ-generated ruthenium catalyst was prepared using [(η 6 -C10H14)RuCl2]2 Ru-4 with various monodentate nitrogen-based ligands at 95 °C in aqueous solution. Based on the experiments, using these ligands, Ru-4 with imidazole was the best catalyst system (initial TOF of 850 h -1 and TON of 515 after 3 h) (Table 1, Entry L), producing 438 mL of hydrogen gas in 7 h, although Ru-4 without any ligands (initial TOF of 560 h -1 and TON of 380 in 3 h) was more effective than substituted imidazole Recently, Singh and colleagues reported the ruthenium-catalyzed dehydrogenation of aqueous formaldehyde and paraformaldehyde to produce hydrogen [45].

Selective Hydrogen Production from Glycerol over Ruthenium Catalyst

“…[3][4][5] Hydrogen is being produced at an industrial scale by electrolysis of water, [6] methane reforming, [7] enzymatic pathway, [8,9] gasification of biomass waste, [10] steam reforming, [11] aqueous phase reforming [12] and catalytic dehydrogenation of liquid hydrogen carriers. [13][14][15][16][17][18][19] However, globally efforts are also being made to explore alternate and effective ways to produce hydrogen gas, and therefore the selection of the sustainable resources and mild reaction conditions for hydrogen production are few of the crucial factors which need specific attention.…”
