Exploring active and stable photocatalysts is an essential requirement for boosting the efficiency of photocatalytic water splitting to obtain clean hydrogen fuel. Here, a few layered black phosphorus/MoS2 (BP-MoS2) nanohybrid was successfully prepared and verified it for photocatalytic hydrogen evolution using CdS nanorods as light absorbers. The resulting nanohybrids manifest remarkable catalytic performance with high amount of H2 production (CdS/BP-MoS2: 183.24 mmol h–1 g–1) and outstanding catalytic stability. The observed amount of H2 is much higher than that of various CdS/BP and CdS/MoS2 based nanohybrids reported earlier. We expect that the demonstrated new heterostructured design strategy may bring novel insights to develop low-price noble metal free photocatalysts for hydrogen evolution.
