Strategic structure modulation of novel quinoxaline-derived liquid organic hydrogen carriers for enhanced dehydrogenation kinetics

We strategically modified methyl groups and N atoms within 2-methylquinoline and present 2-methylquinoxaline and 2,3-dimethylquinoxaline as potential LOHCs with hydrogen storage densities of 6.49 wt% and 5.95 wt%, respectively.
