Hydrogen storage presents {a major|a significant} difficulty {in the|within the|inside the} {development|improvement} of hydrogen economy. Herein, we report {a new|a brand new} electrochemical ethylamine/acetonitrile redox {method|technique|approach|strategy|system|process} for hydrogen storage with an {8|eight}.9 wt.% theoretical storage capacity {under|below|beneath} ambient {conditions|circumstances|situations}. This {method|technique|approach|strategy|system|process} exhibits low onset overpotentials of 0.19 V in CH3CH2NH2 dehydrogenation to CH3CN and 0.09 V in CH3CN hydrogenation to CH3CH2NH2 {using|utilizing|making use of|employing|working with|applying} {commercial|industrial} Pt black catalyst. By assembling a {full|complete} cell that couples CH3CH2NH2/CH3CN redox reactions with hydrogen evolution and oxidation reactions, we demonstrate a {complete|total|full|comprehensive} hydrogen storage cycle at {fast|quick|quickly|rapidly|rapid|speedy} {rates|prices}, with only 52.{5|five} kJ/mol {energy|power} consumption for H2 uptake and release at a {rate|price} of 1 L/m2·h. This {method|technique|approach|strategy|system|process} {provides|offers|gives|supplies|delivers} a viable hydrogen storage {strategy|technique|method|approach|tactic} that meets the 2025 {Department|Division} of {Energy|Power} onboard hydrogen storage target. 2832911-62-1 Purity Price of 2-(4-Nitrophenyl)ethanol PMID:23756629
