Hence, the overall electrochemical properties of the B/P heterojunction have been enhanced by combining the advantages of the individual phosphorene and borophene monolayers, which guarantees the B/P heterojunction as a good candidate for the anode material used in Li-ion batteries. 1. Introduction
To ulteriorly explore the improvement of heterojunction towards Li-S batteries in practical application, S/MnS-MoS 2 cathodes with a sulfur loading of 1.4–1.6 mg cm −2 were assembled for long-term cycling stability test. As a reference, the pure MnS-MoS 2 cathode shows a negligible capacity at 0.2 C ( Fig. S34 ).
The research of heterojunctions pays more attention to the effects brought by the intrinsic feature of the building blocks (e. g., band structures, alignment styles, semiconductor types, carrier concentration, and Fermi level difference) on the electronic structure and electric field distribution of whole materials.
In this work, the B/P heterojunction was constructed as the lattice mismatch between the borophene and the phosphorene monolayer is very small (<4%), and it's expected to show good electrochemical performance as anode materials by combining the advantage of each monolayer.
The formation of this heterojunction structure aims at broadening the solar absorption spectrum of the independent Fe 2 O 3 photoelectrode, negatively shifting the flat band potential of the photoelectrode, reducing the recombination rate of photogenerated electrons/holes.
