Abstract

Abstract: A facile two-step approach is employed to prepare novel Ni2 P@CNT hybrid photocatalyst, which is assembled by nickel phosphide (Ni2 P) nanoparticles on the inner wall of graphitic carbon nitride tube (CNT). This unique microstructure endows Ni2 P@CNT with close interfacial interaction, promotes efficient separation of photoexcited charge carriers and provides enriched sites for photocatalytic reaction. Moreover, the hybrid system is found to exhibit more superior photocatalytic hydrogen evolution activity than pure CNT and Pt-decorated CNT (Pt@CNT). As a consequence, the work illustrates the essential role of experimental process on the final morphology and performance, which is expected to pave a new method to construct various kind of excellent photocatalyst. Highlights: Ni2P nanoparticles are anchored on the inner wall of g-C3N4 tube (CNT). Performance of Ni2 P@CNT is much higher than that of precious metal modified CNT. Synthesis combines supramolecular self-assembly, impregnation and phosphorylation.
