Abstract
The development of effective, low-cost, and stable photocatalysts for visible-light-driven hydrogen production is desired but challenging. Herein, in the presence of a ternary eutectic salt mixture, poly(heptazine imide) with a crystalline–amorphous interface, is synthesized, which endows improved transfer of charge carriers and enhanced photocatalytic activity for hydrogen production.
