Adsorption and activation of molecular oxygen over atomic copper(I/II) site on ceria

Adsorption and activation of molecular oxygen over atomic copper(I/II) site on ceria

Precise control over the energy of atomic metal sites is key to unlocking novel reaction pathways. Here, the authors achieve selective oxygen activation by the isolated copper site on ceria, due to its reduced 3d orbital energy via cerium induced electron withdrawing effect.
