Abstract In artificial photocatalytic hydrogen evolution, effective incident photon absorption and a high‐charge recombination rate are crucial factors influencing the overall efficiency. Herein, traditional solid‐state synthesis is used to obtain, for first time, novel samples of few‐layered g‐C 3 N 4 with vertically aligned MoS 2 loading (MoS /C ). Thiourea layered MoO chosen as precursors, they react under nitrogen atmosphere in situ produce products. According quasi‐Fourier transform infrared reflectance X‐ray diffraction measurements, detailed reaction process determined proceed through confirmed formation pathway. The two precursor units C linked by MoN bonds, which act electronic receivers/conductors hydrogen‐generation sites. Density functional theory also carried out, determines that interface sites electron‐accumulation regions. photoelectrochemical results, can achieve current 0.05 mA cm −2 , almost ten times higher than bare or ‐R reference samples. findings present work pave way not only synthesize series designated but thoroughly understand reaction.
