Strongly coupling of Co9S8/Zn-Co-S heterostructures rooted in carbon nanocages towards efficient oxygen evolution reaction

The design of efficient and nonprecious electrocatalysts towards oxygen evolution reaction (OER) is extremely essential for a wide range of renewable energy technologies but remains a grand challenge. Herein, a novel hybrid composite constructed from Co9S8/Co-doped ZnS (Zn0.8Co0.2S) nanorods with the atomic-level coupled nanointerface rooted in porous carbon polyhedra (Co9S8/Zn0.8Co0.2[email protected]) have been fabricated and investigated as a...
