摘要
Synergetic effects were observed in an oriented-NaNbO3/g-C3N4 heterostructure system synthesized from in situ pyrolysis of urea with hydrothermally prepared NaNbO3 microcuboids. Chemically wrapping NaNbO3 with an appropriate amount of g-C3N4 forms an efficient heterojunction which separates photoexcited charges, and the internal electric field produced by oriented NaNbO3 grains facilitates their transfer. The mechanism developed here is applicable to enhancing photoelectrical utilization in other perovskite systems.
