The combination of 1D nanotubes with 0D nanoparticles to integrate a nanocomposite structure has attracted increasing research interest, while the interfacial interaction plays an important role in such composites. This paper presents a facile and universal approach for the fabrication of hierarchical NP-NT nanocomposites with improved photocatalytic performances by mussel chemistry. Polydopamine (PDA) serves as the biomimetic adhesive layer and then connects MoS2 nanoparticles with g-C3N4 nanotubes (CNNTs). The obtained nanocomposites were characterized by FT-IR spectra, XRD, SEM, TEM, XPS, UV-vis DRS, and PL. Compared with unmodified CNNTs, the as-prepared MoS2-PDA-CNNT composites exhibited an enhanced photocatalytic properties for the degradation of methylene blue (MB) under visible light irradiation. This research would provide a green and versatile method to construct hierarchical structured nanocomposites with high catalytic activity.
