Solar-induced water splitting is a very promising approach for hydrogen production. Molybdenum disulfide (MoS₂) is an important transition metal sulfide to synthesize high-efficient photocatalysts due to its narrow bandgap. However, the low-crystallinity and serious photo-corrosion of MoS₂ generally leads to the weak structural stability, further resulting in the remarkably decreased photocatalytic performance. Herein, the MoS₂ nanostructures were embedded on the surface of 3D porous BN/rGO (BNG) skeleton to fabricate the 3D BNG-MoS₂ (BNG-M) composite. Due to the typical 3D porous structure and synergetic heterointerface, abundant active sites were exposed, and fast interfacial charge mobility and good photoresponsivity were presented, thereby the optimum 3D BNG-M catalyst presented remarkably enhanced HER rate of 1490.3 μmol?h^-1?g^-1 under simulated-solar-light (SSL), which is ~58.2 and ~12.2-fold greater of pure MoS₂ and 3D porous BNG skeleton, and is more prominent than many reported MoS₂ and BN based catalysts. Its apparent quantum yields (AQY) is basically consistent with its UV-vis absorption spectrum. Meanwhile, the prominent durability and reproducibility were achieved by this catalyst. This study provides an important insight to construct the photocatalyst with abundant active sites for achieving high-efficient SSL-induced HER activity.
