Novel 3-D nanoporous graphitic-C3N4 nanosheets with heterostructured modification for efficient visible-light photocatalytic hydrogen production

Phosphorus-doped g-C₃N₄ (P-C₃N₄) nanosheets with unique 3-D nanoporous structures are synthesized for the first time in this work; such functional porous architectures coupled with BiPO₄ nanorods can exhibit superior photocatalytic activity for hydrogen production.
