In this study, a 0D/3D MoS₂/g-C₃N₄ (0D/3D-MCN) photocatalyst with a p-n heterojunction was prepared <i>via</i> a facile light-assisted deposition procedure, and the 3D spongy-like g-C₃N₄ (3D-CN) was synthesized through simple thermolysis of NH₄Cl and melamine mixture. For comparison, 2D-MoS₂ nanosheets were also embedded in 3D-CN by a solution impregnation method to synthesize a 2D/3D-MCN photocatalyst. As a result, the as-prepared 0D/3D-MCN-3.5% composite containing 3.5 wt% 0D-MoS₂ QDs exhibited the highest photocatalytic H₂ evRSC advancesDesign of a p-n heterojunction in 0D/3D MoS₂/g-C₃N₄ composite for boosting the efficient separation of photogenerated carriers with enhanced visible-light-driven H₂ evolution.PMC90540982017ZX072022177710651708356Wu LXiao KZhou BYang BWaqas MZhu CfalseDesign of a p-n heterojunction in 0D/3D MoS₂/g-C₃N₄ composite for boosting the efficient separation of photogenerated carriers with enhanced visible-light-driven H₂ evolution.Constructing a 0D/3D p-n heterojunction is a feasible strategy for accelerating photo-induced charge separation and promoting photocatalytic H₂ production.
