Research progress on the catalytic conversion of ortho-to para-hydrogen
Hydrogen energy is an important renewable energy source with the advantages of high energy density,high calorific value and environmental friendliness.The catalytic conversion of ortho-hydrogen(ortho-H2)to para-hydrogen(para-H2)is an essential step in hydrogen liquefaction which is generally regarded as the critical issue for the massive use of hydrogen energy.Many advances have been achieved regarding mechanism understanding as well as catalyst applications in ortho-to para-H2 conversion,however,a comprehensive and systematic summary is still lacking.We have conducted a comprehensive review of research progress concerning catalytic conversion of ortho-to para-H2,with emphasis on the catalyst technology,catalytic mechanisms,and reaction kinetics.Finally,a brief outlook and prospect on future research is outlined.
