Room-Temperature Activation of Molecular Oxygen Over a Metal-Free Triazine-Decorated sp(2)-Carbon Framework for Green Synthesis

摘要

Additive-free activation of oxygen molecules under ambient conditions has been a great challenge for the green organic synthesis. To make it happen, the design of highly efficient catalyst is the key to make it happen. In this work, we report a simple method to prepare an atomic-scale carbocatalyst via decorating sp(2)-carbon framework with triazine (TA-G), which can activate molecular oxygen for highly efficient organic synthesis. Both theoretical and experimental results reveal that TA-G has a Fermi level lied in the middle of the oxygen 2p antibonding orbital of the absorbed O-2 to weaken the O-O bond for room-temperature and additive-free activation of oxygen molecules.
