Amine-Functionalized ZnO Nanosheets for Efficient CO(2) Capture and Photoreduction

Amine-functionalized ZnO nanosheets were prepared through a one-step hydrothermal method by using monoethanolamine, which has a hydroxyl group, for covalent attachment on ZnO and a primary amine group to supply the amine-functionalization. We demonstrate that the terminal amine groups on ZnO surface...

description Amine-functionalized ZnO nanosheets were prepared through a one-step hydrothermal method by using monoethanolamine, which has a hydroxyl group, for covalent attachment on ZnO and a primary amine group to supply the amine-functionalization. We demonstrate that the terminal amine groups on ZnO surfaces substantially increase the capability of CO(2) capture via chemisorption, resulting in effective CO(2) activation. As a result, the photogenerated electrons from excited ZnO can more readily reduce the surface-activated CO(2), which thereby enhances the activity for photocatalytic CO(2) reduction.
