Abstract

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.
