Design of earth-abundant Z-scheme g-C 3 N 4 /rGO/FeOOH ternary heterojunctions with excellent photocatalytic activity
Iron is one of the most abundant elements on the surface of the earth (5.1%), but is rarely used for photocatalytic hydrogen production due to its unsuitable band structure. Herein, a ternary Z-scheme g-C 3 N 4 /rGO/FeOOH heterostructure photocatalyst for hydrogen production was designed and fabrica...

This work could expand the usage of the earth-abundant element for solar energy conversion and provide a new viewpoint for the development of high-performance photocatalysts through a rational design of the component of the heterostructure. |
