Organic chemical hydrides are one of the most potential methods for hydrogen storage, however, aromatic compound remains unreacted after the hydrogenation process due to equilibrium limitations. To address this, a solid-state adsorbent which could selectively adsorb toluene from methylcyclohexane - toluene mixture was developed. Several La-based oxides were tested and La0.8Ba0.2CoO3-d (LBCO) exhibited high adsorption and selectivity for toluene. Analyses of the electronic state and adsorption state of toluene found part of the Co ions in the LBCO lattice were Co4+. The high oxidation state of Co4+ in the LBCO lattice and surface lattice oxygen mediates the selective adsorption of toluene.
