In order to achieve the sustainable production of hydrogen fuel, heterogeneous photocatalysts with inimitable structure are always desired for high-efficiency and stable H2 reaction from water splitting owing perfect structure-activity relationship. this study, a novel metal-free one-dimensional/two-dimensional (1D/2D) heterojunction is constructed by series dissolution diffusion, recrystallization in-situ growth, self-assembly process 1-pyrene carboxaldehyde (PCHO) nanoribbons on surface polymeric carbon nitride (PCN) nanosheets. The obtained 1D/2D can realize fast carrier transport along 1D prevent recombination photogenerated carriers at interface. Furthermore, intrinsic Z-scheme mechanism within heterostructure also effectively inhibits electron-hole isolates reduction oxidation sites photocatalytic reaction. As result, dramatically enhanced evolution (PHE) activity achieved over 1%-PCHO/PCN sample, optimal PHE rate which approximately 5.4 times that pure PCN. This work provides deep insight into design exploitation unique applied in energy conversion field.

Optimizing charge transfer and alleviating volume expansion in electrode materials are critical to maximize electrochemical performance for energy-storage systems. Herein, an atomically thin soft-rigid Co9 S8 @MoS2 core-shell heterostructure with dual cation vacancies at the atomic interface is constructed as a promising anode high-performance sodium-ion batteries. The involving VCo VMo soft MoS2 shell afford ionic pathways rapid transfer, well rigid core acting dominant active component resisting structural deformation during charge-discharge. Electrochemical testing theoretical calculations demonstrate both excellent Na+ -transfer kinetics pseudocapacitive behavior. Consequently, delivers extraordinary sodium-storage (389.7 mA h g-1 after 500 cycles 5.0 A ), superior those of single-phase counterparts: assembled Na3 V2 (PO4 )3 ||d-Co9 /S-Gr full cell achieves energy density 235.5 Wh kg-1 0.5 C. This finding opens up unique strategy broadens horizons material design storage conversion.
