AbstractIn artificial photocatalytic hydrogen evolution, effective incident photon absorption and a high-charge recombination rate are crucial factors influencing the overall efficiency. Herein, a traditional solid-state synthesis is used to obtain, for the first time, novel samples of few-layered g-C3N4 with vertically aligned MoS2 loading (MoS2/C3N4). Thiourea and layered MoO3 are chosen as precursors, as they react under nitrogen atmosphere to in situ produce the products. According to the quasi-Fourier transform infrared reflectance and X-ray diffraction measurements, the detailed reaction process is determined to proceed through the confirmed formation pathway. The two precursor units MoS2 and C3N4 are linked by MoN bonds, which act as electronic receivers/conductors and hydrogen-generation sites. Density functional theory is also carried out, which determines that the interface sites act as electron-accumulation regions. According to the photoelectrochemical results, MoS2/C3N4 can achieve a current of 0.05 mA cm(-2), which is almost ten times higher than that of bare g-C3N4 or the MoS2/C3N4-R reference samples. The findings in the present work pave the way to not only synthesize a series of designated samples but also thoroughly understand the solid-state reaction.
