A MoS 2 /g‐C 3 N 4 composite was synthesized by a significantly simple method using Na 2 MoO 4 and thiourea as precursors, without the need for a hydrothermal or an ultrasound step. The photocatalytic activity of the synthesized material was evaluated by the degradation of rhodamine B (RhB) in aqueous solution under blue light. The composites with low content of MoS 2 performed better than pure g‐C 3 N 4 . Using a low‐power light‐emitting diode light source, an improvement of two orders of magnitude in the photochemical space‐time yield was achieved, proving enhanced energy efficiency and productivity compared to earlier studies. The degradation pathway of organic pollutants was confirmed by the effects of selective scavengers.
