“…An FTIR spectroscopy study confirmed that antiferromagnetic LaFeO 3 accelerated the nucleus spin conversion of ortho liquid hydrogen (composed of two antiparallel nucleus spins) to para liquid hydrogen (composed of two parallel nucleus spins) to reach equilibrium. 18 Furthermore, Galces-Pineda et al 19 observed that an external magnetic field accelerated oxygen evolution during the electrolysis of water.…”

“…The use of a catalyst generally requires a higher cooling load, and thus an efficiency penalty because the heat of conversion must be removed. Some catalysts include diamagnetic solids, such as germanium or silver [51], copper [52], oxides, including Fe 2 O 3 , Cr 2 O 3 , Gd 2 O 3 , Nd 2 O 3 [53], aluminasupported perovskites (LaFeO 3 /Al 2 O 3 ) [54] or gold nanoparticles [55] among others.…”

Moreover, burning fossil fuels intensifies the emission of greenhouse gases causing catastrophic climatic change. [1] Therefore, an alternative renewable energy with no greenhouse gases emission is highly needed. In this framework, hydrogen (H 2 ) is considered as a promising candidate for carbon-free energy production. [2] Additionally, H 2 is inexhaustibly abundant in nature and endowed with the intriguing features such as the lightest weight in the periodic table and generates high chemical energy of 142 MJ kg −1 per unit mass; about three times greater than the energy produced (47 MJ kg −1 ) by burning hydrocarbons. [3,4] Therefore, continuous efforts are being devoted to replace the conventional liquid hydrocarbon-driven socioeconomic system to hydrogen economy, which embraces the generation of H 2 , its storage, and ultimately energy transfer. [5] However, finding the efficient and economical means of H 2 storage is still a major challenge to be addressed before the practical implication of hydrogen economy. Generally, H 2 can be stored by different strategies including liquefaction method, [6] compression in gas cylinders, [7] adsorption on solid-state materials, [8] solid form as chemical hydrides, [9] and using metastable alloys which can absorb/desorb H 2 with faster kinetics at low temperature. [10] For the onboard applications, H 2 storage capacities should fulfill the goals set by the
