摘要：
A novel crystalline hexagonal prism g-C3N4 (HPCN) was synthesized through hydrothermal recrystallization of flaky g-C3N4 . HPCN exhibits higher-efficiency separation of photocarriers and faster photoelectron transfer along the (002) crystal facet than calcination-formed flaky g-C3N4 (UCN). This significantly shortens the average lifetime of photogenerated carriers in HPCN to 6.0 ns compared with UCN of 15.5 ns. Under visible-light irradiation, the photocatalytic hydrogen evolution of HPCN reaches 1846 mu mol g(-1 )h(-1), and demonstrates excellent photocatalytic stability.
